8.5.41 HS-PDSCH channelisation codes selection for paging reception (FDD and 1.28 Mcps TDD only)

25.3313GPPProtocol specificationRadio Resource Control (RRC)Release 17TS

For FDD, 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 is in UTRAN in CELL_PCH state with variable H_RNTI not set or in URA_PCH state, the UE shall select the channelisation code for HS-PDSCH reception according to the following rules:

1> compile a list of candidate HS-PDSCH channelisation codes from the IE(s) "HS-PDSCH Channelisation Code" in the order of appearance in System Information Block type 5 or System Information Block type 5bis;

1> select a HS-PDSCH channelisation codes from the list of candidate HS-PDSCH channelisation codes based on U-RNTI as follows:

"Index of selected HS-PDSCH channelisation codes" = U_RNTI value mod K,

where K is equal to the number of candidate HS-PDSCH channelisation codes.

For 1.28 Mcps TDD, when the IE "Paging associated HS-PDSCH info" is included in the IE "HS-DSCH paging system information" in System Information Block type 5 and the UE is in CELL_PCH or URA_PCH state, and the variable HS_DSCH_RECEPTION_GENERAL is set to TRUE, the UE shall select the HS-PDSCH according to the following rules:

1> compile a list of candidate HS-PDSCH configuration from IE(s) "Paging associated HS-PDSCH info" in the order of appearance in System Information Block type 5;

1> select an HS-PDSCH configuration from the list of candidate HS-PDSCHs based on U-RNTI as follows:

"Index of selected HS-PDSCH" = U_RNTI value mod K,

where K is equal to the number of candidate HS-PDSCH configuration.
