3GPP TS 25.331 version 12.3.0 Release 12<br />

ETSI TS 125 331 V12.3.0 (2014-10)<br />

1> the UE shall determine the value for the HS_SCCH_LESS_STATUS variable.<br />

The variable HS_SCCH_LESS_STATUS shall be set to TRUE only when all the following conditions are met:<br />

1> the UE is in CELL_DCH state;<br />

1> the variable HS_DSCH_RECEPTION is set to TRUE;<br />

1> no DPDCH is present in uplink and F-DPCH is configured in downlink;<br />

1> the UE is not configured in MIMO mode;<br />

1> the UE is not configured in MIMO mode with four transmit antennas;<br />

1> the variable HS_SCCH_LESS_PARAMS is set;<br />

1> the IE "HS-SCCH less information" is included in the received message.<br />

If any of the above conditions is not met and the variable HS_SCCH_LESS_STATUS is set to TRUE the UE shall:<br />

1> set the variable HS_SCCH_LESS_STATUS to FALSE;<br />

1> clear the variable HS_SCCH_LESS_PARAMS;<br />

1> stop all HS-SCCH less related activities.<br />

If variable HS_SCCH_LESS_STATUS is set to TRUE and the serving HS-DSCH cell was changed as a result of the<br />

received message or HS-SCCH order from the target cell, the UE shall instruct the physical layer to consider that the<br />

HS-SCCH orders from the serving cell were never received.<br />

If the variable HS_SCCH_LESS_STATUS is set to TRUE, the value of IE "HS-SCCH less information" included in the<br />

message is not "Continue HS-SCCH less operation" and the serving HS-DSCH cell was not changed as a result of the<br />

received message, the UE shall instruct the physical layer to consider that the HS-SCCH less related HS-SCCH orders<br />

were never received.<br />

If the variable HS_SCCH_LESS_STATUS is set to TRUE, the value of IE "HS-SCCH less information" included in the<br />

message is "Continue HS-SCCH less operation" and the serving HS-DSCH cell was not changed as a result of the<br />

received message, the UE shall instruct the physical layer to consider that the HS-SCCH less related HS-SCCH orders<br />

were received.<br />

Whenever the variable HS_SCCH_LESS_STATUS is set to TRUE, the UE shall:<br />

1> configure the physical and MAC layers to operate according to the HS_SCCH_LESS_PARAMS;<br />

1> configure the physical layer to use a virtual IR buffer size of at least 4536 bi<strong>ts</strong> for HS-SCCH less HS-DSCH<br />

transmissions.<br />

8.5.36 Actions related to HS_DSCH_RECEPTION_CELL_FACH_STATE<br />

variable (FDD and 1.28 Mcps TDD only)<br />

The variable HS_DSCH_RECEPTION_CELL_FACH_STATE shall be set to TRUE only when all the following<br />

conditions are met:<br />

1> the UE is in CELL_FACH;<br />

1> the UE suppor<strong>ts</strong> HS-DSCH reception in CELL_FACH state;<br />

1> the variable H_RNTI is set;<br />

1> the variable C_RNTI is set;<br />

1> the UE has stored the IE "Added or reconfigured MAC-ehs reordering queue";<br />

1> System Information Block type 5 or System Information Block type 5bis includes IE "HS-DSCH common<br />

system information";<br />
