7.1.8.1 Release of common E-DCH resource when maximum resource allocation for E-DCH expires or uplink transmission ends for CCCH transmission
7.1.8.1.1 Definition and Applicability
All UEs which support E-DCH in CELL_FACH
7.1.8.1.2 Conformance Requirement
Extract from 25.321 11.2.2A:
The allocated common E-DCH resource shall be used by MAC to carry either only CCCH transmission or only DTCH/DCCH transmission, but not both.
The E-DCH enhanced physical random access transmission procedure is completed with release of the allocated common E-DCH resource, if one of the following conditions is fulfilled:
– If the UE according to subclause 8.5.4A in [7] failed to establish the physical channels, or if the criteria for radio link failure are met as specified in subclause 8.5.6 in [7], then the timer T2 is started. After the expiry of T2 a back off timer TBO1 is started. Back off timer TBO1 is set to an integer number NBO1 of 10 ms time intervals, randomly drawn within an interval 0 NBO1min NBO1 NBO1max (with uniform distribution). NBO1min and NBO1max may be set equal when a fixed delay is desired, and even to zero when no delay other than the one due to persistency is desired. The procedure ends if timer TBO1 expires or the UE performs cell reselection while timer TBO1 is running, whatever occurs first. In case of a cell reselection, the timer TBO1 is stopped.
– In case of CCCH transmission, if the maximum E-DCH resource allocation for CCCH has been reached, then this triggers a CMAC-STATUS which informs the RRC about end of the Enhanced Uplink for CELL_FACH state and Idle mode.
– In case of CCCH transmission, if the transmission E-DCH Buffer status is 0 bytes, then the MAC-STATUS-Ind primitive indicates to RLC for each logical channel that no PDU shall be transferred to MAC. If the transmission E-DCH Buffer status is 0 bytes and no MAC-i PDUs are left for (re-)transmission in MAC, then this triggers a CMAC-STATUS which informs the RRC about the end of the Enhanced Uplink for CELL_FACH state and Idle mode.
– In case of DTCH/DCCH transmission, if no E-AGCH with UE’s E-RNTI has been received (through an E-RNTI-specific CRC attachment) within the maximum period for collision resolution phase, then this triggers a CMAC-STATUS which informs the RRC about the end of the Enhanced Uplink for CELL_FACH state and Idle mode. Then the timer T2 is started. After the expiry of T2 a back off timer TBO1 is started. Back off timer TBO1 is set to an integer number NBO1 of 10 ms time intervals, randomly drawn within an interval 0 NBO1min NBO1 NBO1max (with uniform distribution). NBO1min and NBO1max may be set equal when a fixed delay is desired, and even to zero when no delay other than the one due to persistency is desired. The procedure ends when TBO1 expires.
– Explicit common E-DCH resource release:
In case of DTCH/DCCH transmission, if an E-AGCH with UE’s E-RNTI has been received (through an E-RNTI-specific CRC attachment) with absolute grant value set to ‘INACTIVE’, then this triggers a CMAC-STATUS which informs the RRC about end of the Enhanced Uplink for CELL_FACH state and Idle mode.
– Implicit release with E-DCH transmission continuation back off
Implicit resource release is enabled only if "E-DCH transmission continuation back off" is not set to "infinity".
If implicit resource release is enabled, then in case of DTCH/DCCH transmission, the timer Tb is set to "E-DCH transmission continuation back off" value, when TEBS is 0 byte and the last generated MAC-i PDU with higher layer data is provided with the PHY-data-REQ primitive to the physical layer for transmission.
If TEBS <> 0 byte is detected while timer Tb is running, then the timer is stopped and uplink data transmission on the common E-DCH resource continues.
If a MAC-ehs PDU is received while timer Tb is running, then the timer is re-started.
At expiry of timer Tb the MAC-STATUS-Ind primitive indicates to RLC for each logical channel that no PDUs shall be transferred to MAC. TEBS = 0 byte is reported to the Node B MAC as SI in a MAC-i PDU. If the "E-DCH transmission continuation back off" value is set to "0", then the SI should be transmitted with the MAC-i PDU carrying the last DCCH/DTCH data, given the serving grant is sufficient to carry the SI in the same MAC-i PDU together with the remaining DCCH/DTCH data. Otherwise, the empty buffer status report is transmitted separately with the next MAC-i PDU.
If after the expiry of timer Tb no MAC-i PDU is left in a HARQ process for (re-)transmission, then this triggers a CMAC-STATUS which informs the RRC about end of the Enhanced Uplink for CELL_FACH state and Idle mode.
Extract from 25.321 clause 11.8.1.4:
For each MAC-d flow, RRC configures MAC with a HARQ profile and a multiplexing list. Additionally, RRC configures MAC with a power offset for "Control-only" transmissions. This power offset and a maximum number of HARQ transmissions of 8 will be used to define a HARQ profile for “Control-only” transmissions which will be used, 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. The multiplexing list identifies for each MAC-d flow(s), the other MAC-d flows from which data can be multiplexed in a transmission that uses the power offset included in its HARQ profile.
[..]
The E-TFC selection function shall provide this MAC-e PDU and transmission HARQ profile to the HARQ entity. The maximum number of HARQ transmissions and the power offset in this profile, shall be set respectively to the maximum of the Max Number of HARQ Transmissions of the HARQ profiles from all the MAC-d flows from which data is multiplexed into the transmission and to the Nominal Power Offset. The HARQ entity shall also be informed of whether the transmission includes Scheduling Information and whether this information is sent by itself or with higher-layer data.
[…]
if expiry of timer T300 occurs:
the UE shall:
1> check the value of V300; and
2> if V300 is equal to or smaller than N300:
…
3> set the IEs in the RRC CONNECTION REQUEST message according to TS 25.331 subclause 8.1.3.3;
…
3> submit a new RRC CONNECTION REQUEST message to lower layers for transmission on the uplink CCCH;
3> increment counter V300;
3> restart timer T300 when the MAC layer indicates success or failure to transmit the message.
…
2> if V300 is greater than N300:
3> enter idle mode.
3> consider the procedure to be unsuccessful;
3> Other actions the UE shall perform when entering idle mode from connected mode are specified in TS 25.331 subclause 8.5.2;
3> the procedure ends.

7.1.8.1.4 Method of test
Initial conditions
System Simulator:
1 cell, default parameters, Ciphering Off.
User Equipment:
UE: Idle state (state 3 or state 7) as specified in clause 7.4 of TS 34.108 with a CN UE identity, depending on the CN domain(s) supported by the UE.
Test procedure
- SS transmits the PAGING TYPE 1 with cause BCCH modification.
- SS transmits the changed system information SIB 1 and SIB5 / SIB5 bis. UE updates the stored SIBs. The new SIB 5 / SIB5-bis contains the common E-DCH related information.
- SS transmits the PAGING TYPE 1 with cause terminating conversational call.
- SS receives RRC CONNECTION REQ on common E-DCH resource.
- SS transmits a negative HARQ acknowledgement.
- SS transmits a HARQ NACK for each received retransmission.
- The E-DCH resource allocation timer shall expire in UE side which would lead to release of the common E-DCH resource before the specified number of retransmissions.
- SS receives the RRC CONNECTION REQ sent by UE after the expiry of T300
- SS transmits a HARQ ACK for the received transmission.
- UE does not have to send any data ( MAC buffer empty ) which leads to release of the common E-DCH resource. As RRC CONNECTION SETUP is not sent by SS, the UE acquires a common E-DCH resource to transmit RRC CONNECTION REQUEST after expiry of T300.
NOTE 1: There should not be any transmission from UE for the period of T300 after the expiry of E-DCH resource allocation timer.

The SS establishes the reference radio bearer configuration specified in TS 34.108 clause 9.1 using condition “AM Packet to Enhanced CELL_FACH from Enhanced CELL_FACH in PS with SRBs mapped on common E-DCH/HS-DSCH”.
The radio bearer is placed in UE loop-back mode 1 with the UL SDU size set to 10 bytes.
System Simulator
1 cell, default parameters, Ciphering Off
Test procedure
a) UE has common E-DCH resource and allocated E-RNTI to allow data transmission on DTCH. SS sends absolute grant with value of 4 which is sufficient for the UE to transmit data.
b) The SS sends 1 RLC SDU of size 10 bytes on the downlink.
c) The SS receives looped back data on the common E-DCH channel.
d) SS sends Explicit Release on E-AGCH to release the common E-DCH resource.
e) The SS sends 1 RLC SDU of size 10 bytes on the downlink.
f) The SS checks that original common E-DCH channel has been explicitly released by checking that UE initiates a PRACH preamble and Acquisition Indication for a new common E-DCH channel which is used to loop back the data. SS checks the loop back data.

7.1.8.5.1 Definition and Applicability
All UEs which support E-DCH in CELL_FACH
7.1.8.5.2 Conformance Requirement
Extract from 25.211 5.3.3.7.
The use of acquisition indicators is described in [5]. The meaning of acquisition indicators depends on whether a UE sends an access preamble signature corresponding to a PRACH message or corresponding to an E-DCH transmission. Furthermore, if a UE sends an access preamble signature corresponding to an E-DCH transmission, the meaning of the acquisition indicator depends on whether EAI is configured or not. The following rules apply for one PRACH preamble scrambling code. If multiple PRACH preamble scrambling codes are defined in a cell, then for each of them the following rules are used independently.
– If the UE sends an access preamble signature corresponding to a PRACH message, then;
– if an Acquisition Indicator is set to +1, it represents a positive acknowledgement,
– if an Acquisition Indicator is set to -1, it represents a negative acknowledgement.
– If the UE sends an access preamble signature corresponding to an E-DCH transmission, then;
– if the corresponding Acquisition Indicator is set to +1, it represents a positive acknowledgement and the associated default E-DCH resource configuration is allocated to the UE,
– if the corresponding Acquisition Indicator is set to -1 and EAI is not configured, then it represents a negative acknowledgement,
– if the corresponding Acquisition Indicator is set to -1 and EAI is configured, then the UE detects which one of the Extended Acquisition Indicator signatures is present.

7.1.8.6.1 Definition and applicability
Applicable for all UEs supporting Enhanced UL in Cell_FACH.
7.1.8.6.2 Conformance Requirement
[..]
- Implicit release with E-DCH transmission continuation backoff
Implicit resource release is enabled only if "E-DCH transmission continuation back off" is not set to "infinity".
If implicit resource release is enabled, then in case of DTCH/DCCH transmission, the timer Tb is set to "E-DCH transmission continuation back off" value, when TEBS is 0 byte and the last generated MAC-i PDU with higher layer data is provided with the PHY-data-REQ primitive to the physical layer for transmission.
If TEBS <> 0 byte is detected while timer Tb is running, then the timer is stopped and uplink data transmission on the common E-DCH resource continues.
If a MAC-ehs PDU is received while timer Tb is running, then the timer is re-started.
If the "E-DCH transmission continuation back off" value is set to "0" or if timer Tb expires the MAC-STATUS-Ind primitive indicates to RLC for each logical channel that no PDUs shall be transferred to MAC. TEBS = 0 byte is reported to the Node B MAC as SI in a MAC-i PDU. If the "E-DCH transmission continuation back off" value is set to "0", then the SI shall be transmitted with the MAC-i PDU carrying the last DCCH/DTCH data, given the serving grant is sufficient to carry the SI in the same MAC-i PDU together with the remaining DCCH/DTCH data. Otherwise, the empty buffer status report is transmitted separately with the next MAC-i PDU.
CMAC-STATUS-Ind which informs the RRC about the Enhanced Uplink in CELL_FACH state and Idle mode process termination is triggered when the empty buffer status has been reported and no MAC-i PDU is left in any HARQ process for (re-)transmission.
[..]
When "E-DCH transmission continuation back off" is set to "infinity", the Scheduling Information with empty buffer status report shall be transmitted with the MAC-i PDU carrying the last DCCH/DTCH data, given the serving grant is sufficient to carry the SI in the same MAC-i PDU together with the remaining DCCH/DTCH data. Otherwise, the Scheduling Information with empty buffer status report is transmitted separately with the next MAC-i PDU.
[..]
If the UE is sending DTCH or DCCH data, the UE shall release the common E-DCH resource under following conditions:
[..]
– "E-DCH transmission continuation back off" is not set to "infinity", the empty buffer status (TEBS = 0 byte) has been reported and no MAC-i PDU is left in a HARQ process for (re-)transmission.

UE is in Enhanced CELL_FACH state with DTCH/DCCH on common E-DCH / HS-DSCH.
The radio bearer is placed in UE loop-back mode 1 with the UL SDU size set to 10 bytes.
Test procedure
a) UE has common E-DCH resource and allocated E-RNTI to allow data transmission on DTCH. SS sends absolute grant with value of 4 which is sufficient for the UE to transmit data.
b) The SS sends 1 RLC SDU of size 10 bytes on the downlink.
c) The SS receives looped back data on the common E-DCH channel.
NOTE: Data should be looped back before E-DCH-transmission continuation back off period expires.
d) The SS waits sufficient time for the “E-DCH transmission continuation back off” period to expire after loop back data transfer.
e) The SS sends 1 RLC SDU of size 10 bytes on the downlink.
f) The SS checks that original common E-DCH channel has been implicitly released by checking that UE initiates a PRACH preamble and Acquisition Indication for a new common E-DCH channel which is used to loop back the data. SS checks the loop back data.
g) SS checks that all the data is looped back on common E-DCH channel.
h) SS sends Explicit Release on E-AGCH to release the common E-DCH resource.
i) The SS commences required actions for acquisition indication and assignment of a common E-DCH resource for RACH preamble phase.
j) The SS issues an absolute grant on E-AGCH with the UE’s E-RNTI and a signalling value of 4 during the collision resolution phase to allow the UE to transmit data. SS ensure that E-AGCH is received by UE within Maximum period for collision resolution time interval.
k) UE performs PRACH preamble and Acquisition Indication for a common E-DCH resource allocation.
l) After 120TTI, the SS checks that common E-DCH has not been released by checking that there is still transmission on UL DPCCH assigned to that resource.
m) After 120TTI, the SS checks that common E-DCH has not been released by checking that data can be looped back on the existing common E-DCH without PRACH preamble and AICH procedure for acquiring a common E-DCH resource. The SS also checks that the UE includes the SI with TEBS=0 in the same MAC-i PDU together with the DCCH/DTCH data.

a) UE has common E-DCH resource and allocated E-RNTI to allow data transmission on DTCH. SS sends absolute grant with value of 30.
b) The SS sends 1 RLC SDU of size 12 bytes on the downlink.
c) The UE has enough resources to transmit all data and SI with TEBS=0. The SS receives looped back data and a SI with TEBS=0 in the same MAC-i PDU on the common E-DCH channel.
d1) After UE has received the HARQ ACK then is the UE performing an implicit release.
NOTE 1: UE is performing an implicit release as “E-DCH transmission continuation back off" value is set to "0" in broadcasted SIB5 and all data have been transmitted.
d2) The SS sends 1 RLC SDU of size 12 bytes on the downlink.
e) The SS checks that original common E-DCH channel has been implicitly released by checking that UE initiates a PRACH preamble and Acquisition Indication for a new common E-DCH channel which is used to loop back the data. SS sends absolute grant with value of 10 allowing UE to return data only.
NOTE 2: An absolute grant of 10 corresponds to AG Index 5, E-TFCI = 1. TBS = 120 bits. With 24 bits for MAC-i/is header of 24 bits this allows 96 bits for data (12 bytes).
f) The SS receives looped back data only in a MAC-i PDU on the common E-DCH channel.
g) The SS receives a MAC-i PDU with SI with TEBS=0 on the common E-DCH channel.
h) After UE has received the HARQ ACK then is the UE performing an implicit release.
NOTE 3: UE is performing an implicit release as “E-DCH transmission continuation back off" value is set to "0" in broadcasted SIB5 and all data have been transmitted.
i) The SS sends 1 RLC SDU of size 12 bytes on the downlink.
j) The SS checks that original common E-DCH channel has been implicitly released by checking that UE initiates a PRACH preamble and Acquisition Indication for a new common E-DCH channel which is used to loop back the data. SS sends absolute grant with value of 30 allowing UE to return data and SI on the same MAC-i PDU.
k) The UE has enough resources to transmit all data and SI with TEBS=0. The SS receives looped back data and a SI with TEBS=0 in the same MAC-i PDU on the common E-DCH channel.

7.1.8.7 Physical Channel Failure for EUL in CELL-FACH during initial access preamble
7.1.8.7.1 Definition and Applicability
All UEs which support E-DCH in CELL_FACH
7.1.8.7.2 Conformance Requirement
– If the UE according to subclause 8.5.4A in [7] failed to establish the physical channels, or if the criteria for radio link failure are met as specified in subclause 8.5.6 in [7], then the timer T2 is started. After the expiry of T2 a backoff timer TBO1 is started. Backoff timer TBO1 is set to an integer number NBO1 of 10 ms time intervals, randomly drawn within an interval 0 NBO1min NBO1 NBO1max (with uniform distribution). NBO1min and NBO1max may be set equal when a fixed delay is desired, and even to zero when no delay other than the one due to persistency is desired. The procedure ends if timer TBO1 expires or the UE performs cell reselection while timer TBO1 is running, whatever occurs first. In case of a cell reselection, the timer TBO1 is stopped.
[…]
When the physical channel establishment for Enhanced Uplink in CELL_FACH state and Idle mode is initiated by the UE, the UE shall considered the physical channel being immediately established.
If the physical layer considers the post-verification of procedure AA failed [29, section 4.3.2.3A], the UE shall consider this as a "physical channel failure".
NOTE: The criteria defined in this subclause only apply in case the UE performs synchronisation procedure AA (FDD only).
[…]
d) The UE shall start transmission on uplink at the time defined for the Enhanced Uplink in CELL_FACH state and IDLE mode in [1] and shall use a post-verification period for confirming the establishment of the downlink physical channel as follows: During the first 40 ms period of the first phase of the downlink synchronisation procedure the UE shall control its transmitter according to a downlink F-DPCH quality criterion as follows:
– When the UE estimates the F-DPCH quality over the first 40 ms period of the first phase of the downlink synchronisation status evaluation to be worse than a threshold Qin, the UE shall shut its transmitter off and consider post-verification failed. Qin is defined implicitly by the relevant tests in [7].
If the post-verification has failed, the UE shall not transmit on uplink and await higher layer orders.

7.1.8.7.3 Test purpose
To verify that UE detects physical channel failure in the RACH preamble procedure for enhanced uplink in CELL_FACH and ends that access attempt.
7.1.8.7.4 Method of test
Initial conditions
Test case shall be attempted on E-DCH TTI 10msec, irrespective of the device E-DCH category.
System Simulator:
1 cell, default parameters, Ciphering Off.
SS shall broadcast SIB5/SIB5bis with condition B3 “Only for cells which configure common E-DCH and HS-DSCH reception in CELL_FACH”.
User Equipment:
UE: Idle state (state 3 or state 7) as specified in clause 7.4 of TS 34.108 with a CN UE identity, depending on the CN domain(s) supported by the UE.
Test procedure
a) SS does not send F-DPCH.
b) SS transmits the PAGING TYPE 1 with cause terminating conversational call.
c) UE sends an access preamble.
d) SS responds with positive E-AI but does not send F-DPCH.
e) UE detects Physical channel failure
f) UE should end the RACH attempt
g) UE waits for T2 expiry (10ms) + Tbo1 expiry (<= UE shall not attempt another RACH transmission while in waiting for the timer to expire.)
h) UE takes 40 ms to detect the Physical Channel failure at step (d ) after SS has stopped F-DPCH transmission. During this period the UE is not allowed to transmit on uplink, since the additional e-dch transmission back off is set to 5, which means ( (1+5)*10msec tti = 60 msec). Therefore the SS shall not receive the uplink RLC SDU. As in the MAC layer, the check for physical channel failure is done after the data is passed to the physical layer, MAC considers the RRC Connection Request sent although it is actually lost at the physical layer.
i) UE then sends another access preamble. The preamble should be triggered by MAC upon receiving RRC connection request from RRC after T300 expiry.
j) SS responds with E-AI and sends F-DPCH as per normal RACH attempt.
k) The UE sends an RRC connection request
l) SS sends RRC Connection Reject to terminate the procedure

a) The SS establishes the reference radio bearer configuration specified in TS 34.108 clause 6.11.5.4.7.2 using condition A11 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) The SS transmits one RLC SDU of size 320 bits,
d) The SS waits for an E-RUCCHwith SI to be received that indicates that the one RLC SDU is available for transmission (can be identified from the content of the SI)
e) The SS issues an absolute grant that allows the UE to send
f) The SS waits until data is received and verifies that the looped back SDU has correct content
g) The SS opens the UE test loop.
h) The SS release the radio bearer.
i) The SS may optionally deactivate the radio bearer test mode.
