25.3313GPPProtocol specificationRadio Resource Control (RRC)Release 17TS

The variable COMMON_E_DCH_TRANSMISSION shall be set to TRUE only when all the following conditions are met:

1> the UE is in CELL_FACH state or Idle mode;

1> one radio link is configured as the serving E-DCH radio link, and for this radio link the UTRAN has configured the IE "E-HICH info" and the IE "E-AGCH info", and for 1.28Mcps TDD the IE "E-RUCCH Info" and "E-PUCH Info";

1> all logical channels are mapped to E-DCH, and for each of which there is:

2> one E-DCH MAC-d flow is configured, i.e. the IEs "E-DCH MAC-d flow power offset", "E-DCH MAC-d flow maximum number of retransmissions", and for 1.28 Mcps TDD, the IEs "E-DCH MAC-d flow retransmission timer".

If any of the above conditions is not met and the variable COMMON_E_DCH_TRANSMISSION is set to TRUE, the UE shall:

1> set the variable COMMON_E_DCH_TRANSMISSION to FALSE;

1> if not in CELL_DCH state:

2> stop any E-AGCH, E-RGCH (FDD only) and E-HICH reception procedures;

2> for 1.28 Mcps TDD, stop any E-RUCCH and E-PUCH tranmission procedure;

2> act as if the IE "MAC-es/e reset indicator" was received and set to TRUE;

2> release all E-DCH HARQ resources;

2> no longer consider any radio link to be the serving E-DCH radio link.

For FDD, whenever the variable COMMON_E_DCH_TRANSMISSION is set to TRUE, the UE shall:

1> perform uplink DPCCH transmission;

1> if a CCCH message is submitted for transmission on the uplink:

2> no E-AGCH and E-RGCH reception procedure is performed in the physical layer.

1> if a DCCH and/or DTCH message is submitted for transmission on the uplink; or

1> for NodeB triggered HS-DPCCH transmission:

2> use the value stored in the variable E_RNTI as UE identity in the E-AGCH reception procedure in the physical layer;

2> perform E-RGCH reception procedure for the serving radio link if an E-RGCH configuration has been provided with the common E-DCH resource.

2> if variable READY_FOR_COMMON_ERGCH is set to TRUE:

3> determine up to three common E-DCH RL(s) using the procedure specified in subclause 14.1.7 and perform E-RGCH reception on those radio links according to the performance requirements as specified in [19].

1> perform E-HICH reception procedures for the serving E-DCH radio link;

1> perform E-DPCCH transmission procedures for the serving E-DCH radio link;

1> perform E-DPDCH transmission procedures for the serving E-DCH radio link;

1> perform the inclusion of MAC-d PDUs or MAC-c PDUs in a MAC-i PDU for logical channels belonging to the MAC-d or MAC-c flows in accordance with the serving grant (see [15]);

1> if the transmission is a result of receiving an HS-SCCH order for NodeB triggered HS-DPCCH transmission:

2> at the allowed start time of the E-DCH transmission, provide ACK/NACK feedback in accordance with [29] in the physical layer on the serving HS-DSCH radio link, using the information in the IE "Uplink DPCH power control info";

2> at the allowed start time of the E-DCH transmission, use the information for the channel quality indication (CQI) procedure in the physical layer on the serving HS-DSCH radio link, to provide feedback using the information in the IE "Measurement Feedback Info".

1> else:

2> if transmitting DCCH or DTCH data:

3> if IE "ACK/NACK support on HS-DPCCH" is set to TRUE:

4> after collision resolution provide ACK/NACK feedback in accordance with [29] in the physical layer on the serving HS-DSCH radio link, using the information in the IE "Uplink DPCH power control info";

4> after collision resolution use the information for the channel quality indication (CQI) procedure in the physical layer on the serving HS-DSCH radio link if the IE "Measurement Feedback Info" has been provided with the common E-DCH resource.

1> if the UE received the "Enhanced Uplink in CELL_FACH and Idle mode process termination" by MAC with the CMAC-STATUS primitive; or

1> if the UE according to subclause 8.5.4A failed to establish the physical channels; or

1> if the criteria for radio link failure are met as specified in subclause 8.5.6:

2> set the variable COMMON_E_DCH_TRANSMISSION to FALSE;

2> stop any E-AGCH, E-RGCH and E-HICH reception procedures;

2> stop any E-DPCCH and E-DPDCH transmission procedures;

2> act as if the IE "MAC-es/e reset indicator" was received and set to TRUE;

2> release all E-DCH HARQ resources;

2> no longer consider any radio link to be the serving E-DCH radio link;

2> if variable READY_FOR_COMMON_ERGCH is set to TRUE:

3> not consider any radio link to be a Common E-RGCH radio link.

For 1.28 Mcps TDD, whenever the variable COMMON_E_DCH_TRANSMISSION is set to TRUE, the UE shall:

1> if CCCH message is submitted for transmission on the uplink and if the variable E_RNTI is not set:

2> select a common E-RNTI according to subclause 8.5.50;

2> perform E-RUCCH transmission procedure, using the selected common E-RNTI as UE identity;

2> use the selected common E-RNTI as UE identity in the E-AGCH reception procedure in the physical layer in the common E-RNTI scheduling window according to subclause 8.5.50.

1> else:

2> perform E-RUCCH transmission procedure according to the stored PRACH configuration (see [60]), using the value stored in the variable E_RNTI as UE identity;

2> use the value stored in the variable E_RNTI as UE identity in the E-AGCH reception procedure in the physical layer.

1> perform E-HICH reception procedures for the serving E-DCH radio link;

1> perform E-PUCH transmission procedures according to the stored E-PUCH configuration;

1> perform the inclusion of MAC-d PDUs and MAC-c PDUs in a MAC-i PDU for logical channels belonging to the MAC-d flows in accordance with the received scheduling grant on E-AGCH (see [15]).

NOTE: For 1.28 Mcps TDD, when performing E-DCH transmission in CELL_FACH state and Idle mode, the UE shall use the tables of transport block size for the E-DCH physical layer category 3 as specified in [15].

Whenever the variable COMMON_E_DCH_TRANSMISSION is set to FALSE, the UE shall:

1> if not in CELL_DCH state:

2> for FDD, not perform uplink DPCCH transmission;

2> not perform E-AGCH, E-RGCH (FDD only) and E-HICH reception procedures;

2> for FDD, not perform E-DPCCH and/or E-DPDCH transmission procedures;

2> for 1.28 Mcps TDD, not perform E-RUCCH and E-PUCH transmission procedures.

1> for FDD, if variable READY_FOR_COMMON_ERGCH is set to TRUE:

2> not consider any radio link to be a Common E-RGCH radio link.

NOTE: For FDD, if according to subclause 8.5.45, the TTI applied on E-DPDCH is different from the TTI signalled in the IE "E-DCH Transmission Time Interval", then the IE’s "Uplink DPCH power control info" and "Measurement Feedback Info" in fact refer the IE’s "Uplink DPCH power control info for Concurrent TTI" and "Measurement Feedback Info for Concurrent TTI" respectively if present in the IE "Common E-DCH system info parameters for Concurrent TTI" of System Information Block type 22.
