8.5.48 Actions related to HS_DSCH_DRX_CELL_FACH_STATUS variable (FDD and 1.28 Mcps TDD only) and HS_DSCH_DRX_CELL_FACH_2CYCLE_STATUS variable (FDD only)

25.3313GPPProtocol specificationRadio Resource Control (RRC)Release 17TS

The HS-DSCH_DRX_CELL_FACH_2CYCLE_STATUS variable shall be set to TRUE only when the following conditions are met:

1> the UE supports HS-DSCH DRX operation with second DRX cycle in CELL_FACH state;

1> the UE is in CELL_FACH state;

1> the UE has a dedicated H-RNTI configured;

1> the IE’s "HS-DSCH DRX in CELL_FACH Information" and "Common E-DCH system info" have been received from System Information Block Type 5 or System Information Block Type 5bis and the IE "HS-DSCH DRX in CELL_FACH with second DRX cycle Information" has been received from System Information Block Type 22.

If any of the above conditions is not met and the HS_DSCH_DRX_CELL_FACH_2CYCLE _STATUS variable is set to TRUE, the UE shall:

1> stop any ongoing CELL_FACH HS-DSCH DRX operation with second DRX cycle;

1> set the HS_DSCH_DRX_CELL_FACH_2CYCLE _STATUS to FALSE;

1> stop the timer T328, if it is ongoing;

1> stop the timer T329, if it is ongoing.

If the HS-DSCH_DRX_CELL_FACH_2CYCLE_STATUS variable is set to FALSE, the HS_DSCH_DRX_CELL_FACH_STATUS variable shall be set to TRUE only when the following conditions are met:

1> the UE supports HS-DSCH DRX operation in CELL_FACH state;

1> the UE is in CELL_FACH state;

1> the UE has a dedicated H-RNTI configured;

1> the IE "HS-DSCH DRX in CELL_FACH Information" for FDD or IE "HS-DSCH DRX in CELL_FACH Information 1.28 Mcps TDD" for 1.28 Mcps TDD has been received from System Information Block Type 5 or System Information Block Type 5bis;

1> for 1.28 Mcps TDD, UE with dedicated H-RNTI configured, after transitting from CELL_PCH to CELL_FACH state, has detected its dedicated H-RNTI on HS-SCCH indicating HS-DSCH reception;

1> for FDD, either of the following conditions is met:

2> the value of the IE "DRX Interruption by HS-DSCH data" received from System Information Block Type 5 or System Information Block Type 5bis has been set to TRUE; or

2> the UE supports common E-DCH transmission and the IE "Common E-DCH system info" is included in System Information Block type 5 or System Information Block Type 5bis.

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

1> stop any ongoing CELL_FACH HS-DSCH DRX operation;

1> set the HS_DSCH_DRX_CELL_FACH_STATUS to FALSE;

1> stop the timer T321, if it is ongoing.
