If the UE receives RRC CONNECTION SETUP, CELL UPDATE CONFIRM, or any reconfiguration message:

1> the UE shall determine the value for the HS_DSCH_SPS_STATUS variable.

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

1> the UE is in CELL_DCH state;

1> the variable HS_DSCH_RECEPTION is set to TRUE;

1> the IE "HS-DSCH SPS information" is included in the received message and the UE has stored the following IEs in variable HS_DSCH_SPS_PARAMS:

2> IE "Transmission Pattern List";

2> IE "Reception Pattern List";

2> IE "HARQ Info for Semi-Persistent Scheduling".

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

1> set the variable HS_DSCH_SPS_STATUS to FALSE;

1> clear the variable HS_DSCH_SPS_PARAMS;

1> stop all HS-DSCH SPS related activities.

Whenever the variable HS_DSCH_SPS_STATUS is set to TRUE, the UE shall:

1> configure the physical and MAC layers to operate according to the HS_DSCH_SPS_PARAMS.

If variable HS_DSCH_SPS_STATUS is set to TRUE and the serving HS-DSCH cell was changed as a result of the received message and the value of IE "HS-DSCH SPS information" included in this message is "Continue HS-DSCH SPS operation", then UE behaviour is unspecified.
