Void.
A.5.7.1.2 1.28Mcps TDD option
The purpose of this test is to verify the requirement for the delay when performing the serving HS-DSCH cell change in CELL_DCH state specified in section 5.9.
The test parameters are given in Table A.5.7.1 and A.5.7.2 below. The test consists of 3 successive time periods, with a time duration of T1, T2, T3 respectively. At the start of time duration T1 the UE have cell 1 in active set and cell 1 as the serving HS-DSCH cell.
Data shall be transmitted continuously to the UE on the HS-DSCH channel.

1) The test is started at the beginning of T1.
2) During time period T2 an Event 1G triggered measurement report shall be sent by the UE.
3) During time period T2 UTRAN shall send a Physical Channel Configuration command with activation time now changing serving HS-DSCH from cell 1 to cell 2.
4) T3 is defined as the end of the last TTI of Physical Channel Configuration command.

A.5.7.2.2 1.28Mcps TDD option
The UE shall start to transmit the CQI to cell 2 less than 175 ms from the beginning of time period T3.
The UE shall also start to receive the first HS-SCCH message from cell 2 less than 175 ms from the beginning of time period T3 and transmit the ACK or NAK which corresponds to the HS-SCCH message.
NOTE: The delay TDell change = TRRC + Tul/dl sync + Ths-sich/hs-scch interval = 80 + 80 +15 = 175ms.
TRRC RRC procedure delay is defined in TS25.331 Section 13.5.2.
Tul/dl sync Defined as Uplink and Downlink synchronisation time, specified as 80ms.
Ths-sich/hs-scch interval Defined as interval time between HS-SCCH and the corresponding HS-SICH, for 1,28Mcps option specified as 15ms.
