7.1.6a.1.1 MAC-es/e multiplexing without RRC restrictions

7.1.6a.1.1.1 Definition and applicability

All UEs which support E-DCH and 3.84Mcps or 7.68Mcps TDD.

7.1.6a.1.1.2 Conformance requirement

From 25.321 clause 9.1.5:

In the case of E-DCH there are two MAC sublayers, MAC-e and MAC-es. MAC-es sits on top of MAC-e and receives PDUs directly from MAC-d. MAC-es SDUs (i.e. MAC-d PDUs) of the same size, coming from a particular logical channel can be multiplexed together into a single MAC-es payload. To this payload is prepended the MAC-es header (see subclause 9.2.4.1). The number of PDUs, as well as the DDI value identifying the logical channel, the MAC-d flow and the MAC-es SDU size are included as part of the MAC-e header. In case sufficient space is left in the E-DCH transport block or if Scheduling Information needs to be transmitted, an SI will be included at the end of the MAC-e PDU (see subclause 9.2.4.2). Multiple MAC-es PDUs, but only one MAC-e PDU can be transmitted in a TTI.

[…]

From 25.331 clause 8.6.5.18:

1> if the IE "E-DCH MAC-d flow multiplexing list" is included:

2> only multiplex MAC-d PDU’s from the E-DCH MAC-d flow indicated in the IE "E-DCH MAC-d flow identity" with MAC-d PDU’s from E-DCH MAC-d flows with which multiplexing in the same MAC-e PDU is allowed in accordance to the IE "E-DCH MAC-d flow multiplexing list".

7.1.6a.1.1.3 Test purpose

The purpose of this test case is to verify that the UE multiplexes data from different logical channels in the same TTI when no restriction on the multiplexing is configured by RRC.

7.1.6a.1.1.4 Method of test

Initial conditions

System Simulator:

1 cell, default parameters, Ciphering Off.

User Equipment:

The SS establishes the reference radio bearer configuration specified in TS 34.108 clause 6.11.4h using condition A15 as specified in clause 9.1 of TS 34.108. The logical channel, transport channel and queue identities are set to:

Logical Channel ID	MAC-d flow (UL)	Priority	Comment
7 (LCH1)	2	1	RB25
8 (LCH2)	3	2	RB17
Note: The RAB combination also includes SRBs on E-DCH on MAC-d flow 1 which is not used in the testcase

The following parameters are specific for this test case:

Parameter	Value
T-RUCCH	200ms (see 25.331 10.3.6.103)
E-DCH MAC-d flow multiplexing list	11111111 (See 25.331 10.3.5.1b) Note 1
Note 1: This configuration means that all MAC-d flows can be multiplexed in the same TTI

The UE is placed into UE test loop mode 1 with the UL SDU size set to 39 octets for RB25 and RB17.

Test procedure

The UE is configured with two logical channels, LCH1 (with priority 1) and LCH2 (with priority 2). LCH1 is mapped to MAC-d flow 2 and LCH2 is mapped to MAC-d flow 3.

a) The SS has not issued any scheduling grants for E-DCH to the UE

b) The SS transmits one SDU of size 40 bytes (plus 1 byte RLC length indicator) on LCH2

c) The SS transmits one SDU of size 40 bytes (plus 1 byte RLC length indicator) on LCH1

d) The SS waits for an SI to be received that indicates that data is available on both logical channels (can be identified from the content of the SI)

e) The SS issues an absolute grant that allows the UE to send with a high rate (signalling value 10, code resource related value 0 (i.e. SF1) and timeslot resource related information set to indicate all timeslots on which PUCH can be allocated for TDD only; thus allowing a rate well above 2 SDUs/TTI)

f) The SS waits until data is received and verifies that data from the two LCHs is received in the same TTI

NOTE: The UE may send an SI after step 1 but this SI would only indicate data on LCH2. This SI will be ignored.

7.1.6a.1.3.2 Conformance requirement

Extract from 25.321:

[…]

– Transmission Sequence Number (TSN):
The TSN field provides the transmission sequence number for the MAC-es PDU. This information is used for reordering purposes to support in-sequence delivery to higher layers. The length of the TSN field is 6 bits.

[…]

– Data description indicator (DDI):
The DDI field identifies the logical channel, MAC-d flow and size of the MAC-d PDUs concatenated into the associated MAC-es PDU. The mapping between the DDI values and the logical channel ID, MAC-d flow and PDU size is provided by higher layers. The length of the DDI field is 6 bits.

– For FDD: When, due to the quantization in the transport block sizes that can be supported or triggering of the Scheduling Information, the size of the data plus header is less than or equal to the TB size of the E-TFC selected by the UE minus 24 bits, the DDI value [111111] shall be appended at the end of the MAC-e header and a Scheduling Information shall be concatenated into this MAC-e PDU, where DDI value [111111] indicates that there is a Scheduling Information concatenated in this MAC-e PDU. Otherwise, if the size of the data plus header is less than or equal to the TB size of the E-TFC selected by the UE minus 18 bits, a Scheduling Information shall be concatenated into this MAC-e PDU. In any other case it is understood that another MAC-es PDU or Scheduling Information does not fit and it is therefore not necessary to reserve room in the transport block for an additional DDI field.

– For TDD: When, due to the quantization in the transport block sizes that can be supported or triggering of the Scheduling Information (due to timer expiry, see subclauses 11.9.1.4a and 11.9.1.5), the size of the data plus header is less than or equal to the TB size of the E-TFC selected by the UE minus 29bits, the DDI value [111111] shall be appended at the end of the MAC-e header and a Scheduling Information shall be concatenated into this MAC-e PDU, where DDI value [111111] indicates that there is a Scheduling Information concatenated in this MAC-e PDU. Otherwise, if the size of the data plus header is less than or equal to the TB size of the E-TFC selected by the UE minus 23 bits, a Scheduling Information shall be concatenated into this MAC-e PDU. In any other case it is understood that another MAC-es PDU or Scheduling Information does not fit and it is therefore not necessary to reserve room in the transport block for an additional DDI field.

– Number of MAC-d PDUs (N):
The number of consecutive MAC-d PDUs corresponding to the same DDI value. The length of the N field is 6 bits.

7.1.6a.2.1 Correct settings of MAC-es/e scheduling information

7.1.6a.2.1.1 Definition and applicability

All UEs which support E-DCH and 3.84Mcps or 7.68Mcps TDD.

7.1.6a.2.1.2 Conformance requirement

This control information is used by UEs to indicate to the Node B the amount of resources they require. Scheduling Information is sent via the E-PUCH in the MAC-e header when the UE is granted resource and by the E-RUCCH when no resource has been granted. Scheduling Information consists of three components as defined in subclause 9.2.6.3.3 –

– Buffer Information: This consists of:

– Highest priority Logical Channel (HLID)

– Total E-DCH Buffer Status (TEBS)

– Highest priority Logical channel Buffer Status (HLBS)

– UE Power Headroom (UPH): The UPH field indicates the ratio of the maximum UE transmission power and the calculated UE transmit power defined as in [18] that would result for _e equal to 0. The length of UPH is 5 bits.

– Serving and Neighbour Cell Pathloss (SNPL): This may be used by the Node-B to assist with its estimation of the degree of intercell interference each UE will generate and hence the absolute grant power value and physical resources to assign . The length of SNPL is 5 bits.

The length of TEBS field is 5 bits, the values taken by TEBS are shown in Table 9.2.5.3.2-1[in TS25.331]. The length of HLBS is 4 bits, the values taken by HLBS are shown in table 9.2.5.3.2-2 [in TS25.331].

[…]

If a UE has no Grant and the TEBS becomes larger than zero, the transmission of Scheduling Information shall be sent via E-RUCCH.

If the UE has a Grant then Scheduling Information may be included in the MAC-e PDU according to subclause 9.2.4.2. If the UE has a Grant and scheduling information delay timer ≥ T-SCHED then the UE shall include Scheduling Information in the next MAC-e PDU sent and the scheduling information delay timer shall be restarted. If the UE does not receive any Grant before the scheduling information delay timer > T-SCHED + T-RUCCH /2 then the UE shall send scheduling information via the E-RUCCH and shall stop and reset the scheduling information delay timer.

7.1.6a.2.3 MAC-es/e correct handling of scheduled transmissions

7.1.6a.2.3.1 Definition and applicability

All UEs which support E-DCH.

7.1.6a.2.3.2 Conformance requirement

Extract from 25.321 clause 9.2.6.2.1:

The Absolute Grant is sent on downlink on a set of configured E-AGCHs from the serving E-DCH cell and allows the Node B scheduler to directly adjust the granted rate and assigned physical resources for UEs under its control. The physical resource assignment indicates to the UE the maximum amount of uplink resources that it may use for a scheduled transmission.

[…]

The absolute grant message itself includes multiple fields that are multiplexed together into between 14 and 28 bits for 3.84/7.68 Mcps TDD and between 23 and 26 bits for 1.28 Mcps TDD (depending on the system configuration) inside the MAC-e of the Node B and then submitted to the physical layer for transmission on the E-AGCH. These fields are:

– Absolute Grant Value:
For TDD, this field indicates the maximum E-DCH traffic to reference power ratio (E-PUCH/P_e-base) per TDD resource unit that the UE is allowed to use on the E-DCH resources associated with the Absolute Grant. A TDD resource unit is defined as one sixteenth of the OVSF codespace in one timeslot. The length of the Absolute Grant Value field for TDD is 5 bits.

– Channelisation Code:
This field describes the code component of the physical resource grant. For 1.28/3.84 Mcps TDD it comprises an enumerated value of length 5 bits indicating which node on the OVSF code tree has been allocated. For 7.68 Mcps TDD it comprises an enumerated value of length 6 bits indicating which node on the OVSF tree has been allocated. The mapping between the allocated OVSF and the enumerated node 0…30 for 1.28/3.84 Mcps and 0…62 for 7.68 Mcps is as given in [19].

– Timeslot Resource Related Information:
This field describes the timeslot component of the physical resource grant and comprises a bitmap of length n_TRRI indicating which of the timeslots configured for E-DCH use by RRC have been allocated with the LSB corresponding to the lowest numbered E-DCH timeslot and the MSB corresponding to the highest numbered timeslot. The length of the TRRI field (n_TRRI) is 5 bits for 1.28 Mcps TDD and is configurable by RRC on a per-cell basis between 1 and 12 bits for 3.84/7.68 Mcps TDD.

– Resource Duration Indicator:
Optionally, RRC may configure, on a per-cell basis the presence of a resource duration indicator field on E-AGCH for TDD. If configured as present in a cell, 3 bits are used to indicate the number of TTI’s allocated and the spacing between the allocated TTIs via a single grant according to table 9.2.6.2.1-2. If the field is configured as not present on E-AGCH in the cell, a value of 0 is implicitly assumed by the UE corresponding to 1 TTI.

Table 9.2.6.2.1-2 – Resource Duration Indicator (RDI) interpretation

Resource Duration Indicator (3 bits)	TTIs allocated	TTI spacing
0	1	1
1	2	1
2	2	2
3	2	4
4	4	1
5	4	2
6	4	4
7	8	1

– E-AGCH Cyclic Sequence Number (ECSN):
The ECSN is a 3-bit field used to assist the UE with outer-loop power control of E-AGCH (cf. HCSN for HS-SCCH).

E-HICH Indicator(EI) (1.28 Mcps TDD only)
The E-HICH indicator (EI) consists of 2 bits and is used to indicate which E-HICH will convey the acknowledgement indicator for the scheduled UEs.
E-UCCH Number Indicator (ENI) (1.28 Mcps TDD only)
The E-UCCH Number Indicator (ENI) is a 3-bit field used to indicate the detailed number of E-UCCH.

[…]

The UE determines whether each TTI is available for scheduled or non-scheduled transmissions.

The parameters applicable to a transmission are timeslots, code and maximum power. In the case of non-scheduled transmission, these parameters are set by RRC and retransmissions and/or new transmissions may occur in frames at intervals set by RRC. For scheduled transmission, the parameters are received via the E-AGCH.

7.1.6a.2.5 MAC-es/e Correct handling of HARQ profile power offsets

7.1.6a.2.5.1 Definition and applicability

All UEs which support E-DCH.

7.1.6a.2.5.2 Conformance requirement

In TDD, rules for E-TFC selection shall be applied as provided below.

UEs shall apply E-TFC selection when invoked by the HARQ entity (see subclause 11.9.1.1.1).

For each MAC-d flow, RRC configures MAC-e with a HARQ profile and multiplexing list. Additionally, RRC configures MAC with a power offset in case the Scheduling Information needs to be transmitted without any higher- layer data. The HARQ profile includes the power offset and maximum number of HARQ transmissions to use for this MAC-d flow. For 1.28 Mcps TDD, the HARQ profile also includes a retransmission timer attribute. The multiplexing list identifies for each MAC-d flow(s), the other MAC-d flows for which data can be multiplexed in a transmission that uses the power offset included in its HARQ profile.

RRC can control the scheduling of uplink data by giving each logical channel a priority between 1 and 8, where 1 is the highest priority and 8 the lowest. E-TFC selection in the UE shall be done in accordance with the priorities indicated by RRC. Logical channels have absolute priority, i.e. the UE shall maximise the transmission of higher priority data.

RRC can allocate non-scheduled transmission grants to individual MAC-d flows in order to reduce the transmission delays.

The UE shall determine whether to take scheduled or non-scheduled grants into account in the upcoming transmission. If neither are supposed to be taken into account (i.e. the TTI is not available for non-scheduled transmission and no Grant for scheduled transmission has been received) then no grant shall be assumed to exist. If a grant exists then the transmission format and data allocation shall follow the requirements below.

For each configured MAC-d flow, a given E-TFC can be in any of the following states:

– Supported state;

– Blocked state.

The E-TFC states are derived according to the following:

If the transmission is a retransmission then only the E-TFC with the same block size as the original transmission may be in the supported state.
For 1.28Mcps TDD, only E-TFCs from the E-TFCS (the table of TB sizes) which are consistent with the UE’s E-DCH capability category shall be considered for the transmission;
Only E-TFCs from the E-TFCS (the table of TB sizes) which can be supported by (exactly) the number of slots assigned by the grant shall be considered for the transmission;
Only E-TFCs which result (for the granted timeslot and code physical resources) in a code rate lying between the maximum and minimum (inclusive) allowable code rates set by RRC [7] shall be considered for the transmission {note: the definition of the term “code rate” as used here is the same as that provided by [18]}. This shall be evaluated for both QPSK and 16-QAM modulation;
P_HARQ, the HARQ profile power offset is selected (the HARQ profile for the transmission shall be selected among the HARQ profiles of MAC-d flows on which the highest priority logical channels with available data are mapped; Scheduling Information power offset shall be used when Scheduling Information is transmitted without any higher-layer data.)
Only E-TFCs whose calculated transmission power requirement P_E-PUCH (see [18]) is less than or equal to the available or granted power shall be considered for the transmission (note: this requirement does not apply in the case of a retransmission on non-scheduled resources).

For 3.84Mcps/7.68Mcps TDD, from those E-TFCs in the supported state the UE determines the largest block size that it is permitted to transmit within the given constraints.

For 1.28Mcps TDD, from those E-TFCs in the supported state, UE determines a candidate set with up to 64 E-TFCs, including the largest 63 E-TFCs, in addition to the E-TFC dedicated for SI. If the number of E-TFCs in the supported state is not greater than 63, all the E-TFCs in the supported state shall be included in the candidate set. The E-TFCs in the candidate set shall then be re-indexed in an ascending order and numbered from 0 to (Nmax -1), where Nmax is the number of E-TFC in the candidate set. From the candidate set the UE determines the largest block size that is permitted to transmit within the given constraints.

The UE shall select the modulation type associated with the determined E-TFC (note: if an E-TFC is supported by both QPSK and 16-QAM then 16-QAM modulation shall be used if its power requirement (P_E-PUCH) is lower than the power requirement for QPSK, otherwise QPSK modulation shall be used).

Data allocation shall then be performed in accordance with the following:

– The data allocation shall maximise the transmission of higher priority data;

– The UE shall select the E-TFC, SF and modulation which minimises the power used (3.84/7.68 Mcps TDD only);

– The UE shall select the E-TFC and modulation which minimises the power used (1.28 Mcps TDD only);

Once an appropriate E-TFC and data allocation are found according to the rules above, the "Multiplexing and TSN Setting" entity shall generate the corresponding MAC-e PDU.

In 1.28Mcps TDD, when Scheduling Information is triggered by timer per subclause 11.9.1.5, the E-TFC selection and data-allocation process shall assume that Scheduling Information has a priority higher than any other logical channel.

The E-TFC selection function shall provide this MAC-e PDU and transmission HARQ profile to the HARQ entity. The selected E-TFC is also provided (Note: for 1.28Mcps TDD, the signalled transport block size index, i.e. E-TFCI, is the index of the selected E-TFC in the candidate set.). The maximum number of HARQ transmissions and the power offset in this profile shall be set respectively to the maximum of both the Max Number of HARQ Transmissions and of the power offset of the HARQ profiles from all the MAC-d flows from which data is multiplexed into the transmission. For 1.28 Mcps TDD, the retransmission timer shall be set to the maximum of the retransmission timer value of the HARQ profiles that are permitted to be multiplexed into the transmission. Each HARQ process which is associated with a buffer holding a MAC-e PDU for potential retransmission shall maintain the HARQ profile and the number of re-transmissions that have occurred. For 1.28 Mcps TDD, the HARQ process shall also maintain the value of RTX_TIMER.

a) The SS has not issued any scheduling grant for E-DCH to the UE

b) The SS transmits one SDU of size 40 bytes (plus 1 byte RLC length indicator) on LCH2

c) The SS transmits one SDU of size 40 bytes (plus 1 byte RLC length indicator) on LCH1

d) The SS waits for an SI to be received that indicates that data is available on both logical channels (can be identified from the content of the SI)

e) The SS issues an absolute grant that allows the UE to send 1 RLC PDU per TTI (signalling value 4)

f) The SS verifies that the first TTIs only contains data from LCH1 which have a higher priority

g) The SS verifies that data on LCH2 is only transmitted after all the data on LCH1 has been looped back

For 3.84 Mcps TDD, the normative description of the mapping between the E-TFC index and the corresponding transport block size is provided in Annex BA.

For 7.68 Mcps TDD, the normative description of the mapping between the E-TFC index and the corresponding transport block size is provided in Annex BB.

[…]

For 3.84 Mcps TDD, the mapping of transport block size L to signalled index k_i = {0,1,…127} (see Annex BA.1) is given by the formula:

In the above formula, k_i is the TBS index (0…127) and k_n is an integer selected based upon the number of timeslots allocated (n). Values for k_n are tabulated in Table 9.2.6.4.1.

NOTE 1: Applicable indexes depends on the UE capability of “Maximum number of bits of an E-DCH transport block transmitted within a 10 ms E-DCH TTI” as specified in TS 25.306 clause 5.1.

Test procedure

a) The SS establishes the reference radio bearer configuration specified in TS 34.108 clause 6.10.3.4.7.1 for 3.84Mcps and clause 6.11.6.4.7.1 for 7.68Mcps using condition A12 as specified in clause 9.1 of TS 34.108.. See note 1.

b) The SS closes the test loop using UE test loop mode 1 and configuring the UL RLC SDU size to be equal to the received DL SDU size (i.e. not setting the UL RLC SDU size parameter).

c) SS sets RLC SDU size = 312 bits which corresponds to maximum AM payload size for 1 MAC-d PDU of size 336 bits.

d) The SS removes the scheduling grant for E-DCH for the UE.

e) If N_PDUs is less than 36 the SS transmits one RLC SDU with size ((NPDUs – 1) * 320 + 312) else the SS transmits two SDUs with size ((N_PDUs – 2) * 320 + 2 * 312) / 2. See note 2.

f) The SS waits for an SI to be received that indicates that there is data available for transmission (can be identified from the content of the SI). See Note 3. The SS checks that TEBS and HLBS have the correct values.

g) The SS issues an absolute grant that allows the UE to which specifies the maximum absolute grant value (signalled value 31) together with a physical resource allocation of the whole code space (signalled value 0) and TS allocation limited to the number of timeslots defined in Table 7.1.6a.3.2 for 3.84Mcps and in Table 7.1.6a.3.4 for 7.68Mcps for the sub-test. The resource duration takes the default value of 1 TTI.

h) The SS waits until data is received and verifies that the looped back SDU data has the correct content and is sent in the same TTI.

i) The SS verifies that the received E-TFC used by the UE is correct. For Rel-7 and later release UE the SS checks that the UE has not used the transport block sizes correspondent to the E-TFCI values as listed in table 7.1.6.3.2.6, but instead used the transport block size correspondent to the next possible larger E-TFCI value.

j) The SS increments the RLC SDU payload size by 320 bits. For the case of 2 SDUs transmitted by the SS, each of the payload sizes are incremented by 320 bits. The SS calculates the new E-TFC transport block size from the relevant Transport Block Size Table. If this transport block size is supported by the UE under test, according to Table 7.1.6.3.2.5, then continue with step d else continue with step k.

k) The SS opens the UE test loop.

l) The SS release the radio bearer.

m) The SS may optionally deactivate the radio bearer test mode.

NOTE 1: The SS configures the physical channel parameters according to the actual UE category under test.

NOTE 2: Calculation of Downlink (DL) RLC SDU size:

DL SDU size = N_PDUs * 336 bits RLC PDU – headers associated with MAC and RLC.

RLC PDU = RLC 16 bits Sequence Number + 8 bits for the Optional Length Indicators + RLC pay load size. The Optional Length Indicator is present only in the delivery of the last RLC PDU.

The Optional Length Indicators consists of a 7 bits Length Indicator + 1 bit Extension Field of binary value = “0”. The 7 bit length indicator indicates the number of octets between the end of the RLC header up to and including the last octet of the (DL) RLC SDU ending within the PDU.

Therefore, the RLC payload has two different sizes of 320 bits (336 – 16 bits Sequence Number) and 312 bits (336 – 16 bits sequence Number – (7 bits Length Indicator + 1 bit extension field)).

N_PDUs = FLOOR ( (TBS size – MAC-e header size – MAC-es header size) / MAC-d PDU size) = FLOOR ( (TBS size -18) / 336).

For N_PDUs = 1

DL RLC SDU payload has size 312 bits

For 1 < N_PDUs < 36

There are (N_PDUs – 1) RLC payloads of size 320 bits with the last RLC payload size 312 bits

DL RLC SDU payload size = (N_PDUs -1) * 320 + 312

For N_PDUs ≥ 36

The test data for transport channels on HS-DSCH and E-DCH is divided into 2 RLC SDUs so that the SDU size does not exceed 1500 octets (limit of SDU size in SM)

The payload data of the MAC-d PDUs contains 2 RLC SDUs of size

((N_PDUs – 2) * 320 + 2 * 312) / 2

N_PDU = N_PDUs + 2

Calculation of E-TFC TB Size:

Select the E-TFC Index/TB Size = Number of MAC-d PDU * 336 bits RLC PDU + 336 bits UL AM ACK (status) PDU + 18 bits MAC-es and MAC-e headers (6 bits N + 6 bits TSN + 6 bits DDI) according to the E-DCH Transport Block Size Tables for FDD per 25.321 Annex B, .

As an example TBS value of 716 bits is used by the UE in the 10mS Index 0 subtest to deliver UL RLC SDU size o f 84 bytes = 672bit + 18 bits MAC headers = 690 bits

NOTE 3: Calculation of TEBS value:

Using the E-TFC TB size determined in Note 2 above, select the TEBS index according to 25.321 Table 9.2.5.3.2-1.

i) The SS waits for an SI to be received that indicates that data is available on both LCHs.

j) The SS issues an absolute grant that allows the UE to send with a rate sufficient to accommodate two RLC PDUs per TTI (signalling value 5)

k) For each received transmission, the SS sends a negative HARQ acknowledgement and verifies that exactly 4 retransmissions are made by the UE (maximum from the HARQ profiles for LCH1 and LCH2).

NOTE: The UE may send an SI after step g but this SI would only indicate data on LCH2. This SI will be ignored.
