8.5.69 Actions related to UPLINK_CLTD_TRANSMISSION variable (FDD only)

25.3313GPPProtocol specificationRadio Resource Control (RRC)Release 17TS

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

1> the UE is in CELL_DCH state;

1> the UE has stored IE "Uplink CLTD info FDD";

1> the UE has stored IE "F-TPICH info" for the radio link transmitted from the serving HS-DSCH cell if HS-DSCH is configured or from the cell identified by the IE "Primary CPICH info" in the IE "Uplink CLTD info FDD" if only DCH is configured;

1> the UE is configured with MAC-i/is if E-DCH is configured;

1> the variable SECONDARY_CELL_E_DCH_TRANSMISSION is set to FALSE if the UE supports Dual Cell E-DCH operation.

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

1> set the variable UPLINK_CLTD_TRANSMISSION to FALSE;

1> stop the F-TPICH reception procedure;

1> trigger lower layers to stop the uplink CLTD transmission;

1> clear the stored IE "Uplink CLTD info FDD".

If all of the above conditions are met and the variable UPLINK_CLTD_TRANSMISSION is set to FALSE, the UE shall:

1> set the variable UPLINK_CLTD_TRANSMISSION to TRUE;

1> instruct the physical layer to switch to the uplink CLTD activation state as indicated by the IE "Initial CLTD activation state" (see [27]).

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

1> perform the F-TPICH reception procedure;

1> trigger lower layers to perform the uplink CLTD transmission.

Whenever the variable UPLINK_CLTD_TRANSMISSION is set to FALSE, the UE shall:

1> not perform the F-TPICH reception procedure;

1> not perform the uplink CLTD transmission.

If the variable UPLINK_CLTD_TRANSMISSION is set to TRUE and the serving HS-DSCH cell was changed as a result of the received message or HS-SCCH order from the target cell, and the IE "Initial CLTD activation state" is included, the UE shall instruct the physical layer to switch to the uplink CLTD activation state as indicated by the IE "Initial CLTD activation state" (see [27]).

If the variable UPLINK_CLTD_TRANSMISSION is set to TRUE, and the serving HS-DSCH cell was changed as a result of the received message or HS-SCCH order from the target cell, and the IE "Uplink CLTD info FDD" is included, and the IE "Initial CLTD activation state" is not included, the UE shall instruct the physical layer to remember the received uplink CLTD activation state switching HS-SCCH orders.

If the variable UPLINK_CLTD_TRANSMISSION is set to TRUE, and the value of IE "Configuration info" contained in the IE "Uplink CLTD info FDD" is set to either "Continue" or "New configuration", and the serving HS-DSCH cell was not changed as a result of the received message, the UE shall instruct the physical layer to remember the received uplink CLTD activation state switching HS-SCCH orders.
