3> use STTD for these E-AGCH, E-RGCH, and E-HICH.
2> otherwise:
3> not use Tx diversity for these E-AGCH, E-RGCH, and E-HICH.
For F-TPICH, the UE shall:
1> for each radio link:
2> if the DPCH associated with the F-TPICH is using either open or closed loop transmit diversity:
3> use STTD for the F-TPICH.
2> if the F-DPCH associated with the F-TPICH is using open loop transmit diversity:
3> use STTD for the F-TPICH.
2> otherwise:
3> not use Tx diversity for the F-TPICH.
NOTE: The IE "Tx Diversity Mode" shall be ignored with respect to the radio links that are in the secondary E-
DCH active set.
8.6.6.25 Void
8.6.6.26 UL Timing Advance Control (TDD only)
If the IE "UL Timing Advance Control" is present, the UE shall:
1> if the IE "Uplink Timing Advance Control" has the value "disabled":
2> reset timing advance to 0;
2> disable calculated timing advance following handover;
2> in case of handover:
3> start uplink transmissions in the target cell without applying timing advance.
1> if the IE "Uplink Timing Advance Control" has the value "enabled":
2> in 3.84 Mcps TDD or 7.68 Mcps TDD:
3> in case of no cell change:
4> evaluate and apply the timing advance value for uplink transmission as indicated in the IE "Uplink
Timing Advance" or the IE "Extended Uplink Timing Advance" at the CFN indicated in the IE
"Activation Time".
3> in case of cell change:
4> use the IE "Uplink Timing Advance" or the IE "Extended UL Timing Advance" as TA old and apply
TA new for uplink transmission in the target cell at the CFN indicated in the IE "Activation Time" as
specified in [33];
4> include the value of the applied timing advance in the IE "Timing Advance" or the IE "Extended UL
Timing Advance" in the COMPLETE message.
2> in 1.28 Mcps TDD:
3> if the IE "Synchronisation parameters" is included:
