A.7.1 Timing Advance
A.7.1.1 3.84 Mcps TDD option
A.7.1.1.1 Test Purpose and Environment
The purpose of this test is to verify the requirements on timing advance adjustment accuracy and timing advance adjustment delay in section 7.1.1.
The test parameters are given in table A.7.1 and table A.7.1A. The test consists of two successive time periods, with a time duration of T1and T2 respectively. At the start of time duration T1, the UE shall transmit with the Uplink Timing Advance value set to zero, i.e. Timing Advance disabled.
During time period T1, UTRAN shall send an Uplink Physical Channel control message with activation time at the beginning of T2. The Uplink Physical Channel Control message shall be sent to the UE such that the delay between the end of the last received TTI containing the message and the beginning of T2 is greater than or equal to the RRC procedure delay as defined in [16].

A.7.4.2.2 Uplink synchronization control during handover
A.7.4.2.2.1 Scenario 1: Handover to intra-frequency cell
This test case is applicable for UE handovers in single frequency network and UE handovers from primary frequency to primary frequency in multi-frequency network.
A.7.4.2.2.1.1 Test Purpose and Environment
The purpose of this test is to verify the requirement for the uplink synchronization control during intra-frequency handover in CELL_DCH state as reported in section 7.5.2.2.
The test parameters are given in Tables A.7.4.4 and A.7.4.5 below. The test consists of three successive time periods, with a time duration of T1, T2 and T3 respectively. At the start of time duration T1, the UE may not have any timing information of cell 2.
UTRAN shall send a Physical Channel reconfiguration with activation time "now" at the beginning of T3 with a new active cell, cell 2, after the UE has reported event 1G. The starting point of T3 is defined as the end of the last TTI containing the physical channel reconfiguration message.
UTRAN measures the initial uplink synchronization timing position of the first uplink DPCH on the target cell and compares it with the desired position. If the difference dose not exceed the accuracy requirements in section 7.5.2.2, it is recorded as success once.
