8.5.40a HS_DSCH Reception in CELL_PCH and URA_PCH (1.28 Mcps TDD only)

25.3313GPPProtocol specificationRadio Resource Control (RRC)Release 17TS

When the IE "HS-DSCH paging system information" is included in System Information Block type 5 and the UE is in CELL_PCH or URA_PCH state, the UE shall:

1> if variable H_RNTI and variable C_RNTI are set:

2> if the UE is in CELL_PCH state:

3> set the variable HS_DSCH_RECEPTION_GENERAL to TRUE;

3> use the value of the variable H_RNTI as UE identity in the HS-SCCH reception procedure in the physical layer for DCCH or DTCH reception; and

3> for BCCH reception perform HS-DSCH reception procedures by listening to the first indexed HS-SCCH code listed in the IE "HS-SCCH channelisation code" for FDD or first instance in the IE "HS-SCCH Set Configuration" for 1.28 Mcps TDD with "BCCH specific H-RNTI" as received in IE "HS-DSCH common system information" from System Information Block type 5 or System Information Block type 5bis;

3> if the UE detects the value of the variable H_RNTI in the HS-SCCH reception procedure:

4> initiate the enhanced uplink synchronization procedure;

4> move to CELL_FACH;

4> stop timer T319 if it is running.

3> if the UE has uplink RLC data PDU or uplink RLC control PDU on RB1 or upwards to transmit:

4> move to CELL_FACH state;

4> stop timer T319 if it is running.

2> if the UE is in URA_PCH state:

3> clear the variable H_RNTI;

3> clear the variable C_RNTI;

3> clear any stored IE "HARQ Info";

3> reset the MAC-ehs entity [15];

3> if the IE "PICH info" isn’t included in IE "Secondary CCPCH system information" in System Information Block type 5 or System Information Block type 6:

4> set the variable HS_DSCH_RECEPTION_GENERAL to TRUE;

4> perform the HS-DSCH reception procedure according to IE "HS-DSCH paging system information" as received in System Information Block type 5:

5> receive the HS-PDSCH applying the configuration according to 8.5.41 in "Paging Sub-Channel Size" * 2 consecutive TTIs and use the Transport block sizes indexed in the IE "Transport Block Size List" for demultiplexing of upper layer PDUs from transport blocks delivered from the physical layer on HS-DSCH, as described in [33].

1> else:

2> if variable H_RNTI or variable C_RNTI are set:

3> clear the variable H_RNTI;

3> clear the variable C_RNTI;

3> clear any stored IE "HARQ Info";

3> reset the MAC-ehs entity [15].

2> if the IE "PICH info" isn’t included in IE "Secondary CCPCH system information" in System Information Block type 5 or System Information Block type 6:

3> set the variable HS_DSCH_RECEPTION_GENERAL to TRUE;

3> perform the HS-DSCH reception procedure according to IE "HS-DSCH paging system information" as received in System Information Block type 5, receive the HS-PDSCH applying:

4> HS-PDSCH configuration selected according to 8.5.41 in "Paging Sub-Channel Size" * 2 consecutive TTIs;

4> the Transport block sizes indexed in the IE "Transport Block Size List" for demultiplexing of upper layer PDUs from transport blocks delivered from the physical layer on HS-DSCH, as described in [33].

NOTE : When performing HS-DSCH reception in CELL_PCH and URA_PCH state, the UE shall use the table of transport block size for the HS-DSCH physical layer category 9 as specified in [15].
