1> else:
2> indicate to lower layers to start operation in MIMO mode with four transmit antennas on that secondary
serving HS-DSCH cell, using the parameter values stored in the corresponding entry in the variable
SECONDARY_CELL_MIMO_MODE_WITH_FOUR_TRANSMIT_ANTENNAS_PARAMS.
1> when MIMO mode with four transmit antennas only with dual stream restriction is configured:
2> if MAC-ehs is not configured:
3> the UE behaviour is undefined.
8.5.81 Actions related to UPLINK_MIMO_TRANSMISSION variable (FDD
only)
The variable UPLINK_MIMO_TRANSMISSION shall be set to TRUE only when all the following conditions are met:
1> the UE is in CELL_DCH state;
1> the variable UPLINK _CLTD_TRANSMISSION is set to TRUE;
1> the variable HS_DSCH_RECEPTION is set to TRUE;
1> the variable E-DCH transmission is set to TRUE:
1> the UE has stored IE "Uplink MIMO info FDD";
1> the UE has stored IE "E-ROCH info FDD";
1> the UE has stored "E-TFC Boost Info";
1> the UE is configured with MAC-i/is.
If any of the above conditions is not met and the variable UPLINK_MIMO_TRANSMISSION is set to TRUE, the UE
shall:
1> set the variable UPLINK_MIMO_TRANSMISSION to FALSE;
1> indicate to lower layers to stop the uplink MIMO transmission;
1> do not configure "TSN field extension" for the MAC-i/is entity;
1> reset the MAC-i/is entity;
1> clear the stored IE "Uplink MIMO info FDD";
1> if configured, clear the stored E-HICH configuration for the secondary stream.
If all of the above conditions are met and the variable UPLINK_MIMO_TRANSMISSION is set to FALSE, the UE
shall:
1> set the variable UPLINK_MIMO_TRANSMISSION to TRUE;
1> reset MAC-i/is entity;
1> configure "TSN field extension" for MAC-i/is entity;
1> indicate to lower layers to start the uplink MIMO transmission in rank1.
Whenever the variable UPLINK_MIMO_TRANSMISSION is set to FALSE, the UE shall:
1> stop the uplink MIMO transmission.
If the variable UPLINK_MIMO_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, the UE shall instruct the physical layer to switch
to the uplink MIMO transmission in rank1.
