8.5.40 HS_DSCH Reception in CELL_PCH and URA_PCH (FDD 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 or System Information Block type 5bis and the UE supports HS-DSCH reception in CELL_PCH and URA_PCH state and the UE is in CELL_PCH or URA_PCH state, the UE shall:

1> set the variable HS_DSCH_RECEPTION_GENERAL to TRUE;

1> use the octet aligned HS-DSCH transport block table [15] in the MAC-ehs entity;

1> if variable H_RNTI and variable C_RNTI are set and UE is in CELL_PCH state:

2> determine the "Total number of soft channel bits" (defined in Table 5.1a of [35]) according to subclause 8.1.6.2 and use it in the physical layer;

2> for DCCH or DTCH reception:

3> use the value of the variable H_RNTI as UE identity in the HS-SCCH reception procedure in the physical layer.

2> for BCCH reception:

3> perform HS-DSCH reception procedures by listening to the first indexed HS-SCCH code listed in the IE "HS-SCCH channelisation code" 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.

2> if the UE detects the value of the variable H_RNTI in the HS-SCCH reception procedure; and

2> if the value of the variable READY_FOR_COMMON_EDCH has not been changed due to a system information modification:

3> move to CELL_FACH and initiate the measurement report procedure as specified in subclause 8.4.2;

3> start to receive HS-DSCH according to the procedure in subclause 8.5.36;

3> stop timer T319 if it is running;

3> restart the timer T305 if it is set to any value other than "infinity".

2> if the UE has uplink RLC data PDU or uplink RLC control PDU on RB1 or upwards to transmit; and

2> if the value of the variable READY_FOR_COMMON_EDCH has not been changed due to a system information modification:

3> move to CELL_FACH and initiate the measurement report procedure as specified in subclause 8.4.2;

3> start to receive HS-DSCH according to the procedure in subclause 8.5.36;

3> stop timer T319 if it is running;

3> restart the timer T305 if it is set to any value other than "infinity".

1> else:

2> if variable H_RNTI or variable C_RNTI are set, or if the UE is in URA_PCH state and variable H_RNTI or variable C_RNTI or E-RNTI is not 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> perform the HS-DSCH reception procedure according to IE "HS-DSCH paging system information" as received in System Information Block type 5 or System Information Block type 5bis, receive the HS-PDSCH applying:

3> a scrambling code as received in the IE "DL Scrambling code";

3> a channelisation code selected according to 8.5.41 in "Number of PCCH transmissions" consecutive TTIs;

3> 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 [29]; and

3> configure the physical layer to use the "Total number of soft channel bits" (defined in Table 5.1a of [35]) for category 12 for HS-DSCH reception.
