A.5.2 FDD/FDD Hard Handover
25.1333GPPRelease 17Requirements for support of radio resource management (FDD)TS
A.5.2.1 Handover to intra-frequency cell
A.5.2.1.1 Test Purpose and Environment
The purpose of this test is to verify the requirement for the hard handover delay in CELL_DCH state in the single carrier case reported in section 5.2.2.1.
The test parameters are given in Table A.5.0 and A.5.0A below. In the measurement control information it is indicated to the UE that event-triggered reporting with Event 1A and 1B shall be used, and that CPICH Ec/Io and SFN-CFN observed timed difference shall be reported together with Event 1A. 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" with a new active cell, cell 2. The Physical Channel reconfiguration message shall be sent to the UE during period T2, after the UE has reported event 1A. T3 is defined as the end of the last TTI containing the physical channel reconfiguration message.

Note 1: The DPCH level is controlled by the power control loop Note 2: The power of the OCNS channel that is added shall make the total power from the cell to be equal to Ior . Note 3: The DPCH may not be power controlled by the power control loop. |
A.5.2.1.2 Test Requirements
The UE shall start to transmit the UL DPCCH to Cell 2 less than 190 ms from the beginning of time period T3.
The rate of correct handovers observed during repeated tests shall be at least 90%.
A.5.2.2 Handover to inter-frequency cell
A.5.2.2.1 Test Purpose and Environment
The purpose of this test is to verify the requirement for the inter frequency hard handover delay in CELL_DCH state as specified in section 5.2.2.1.
The test consists of three successive time periods, with a time duration T1, T2 and T3. The test parameters are given in tables A.5.0B and A.5.0C below. In the measurement control information it is indicated to the UE that event-triggered reporting with Event 2C shall be used. The CPICH Ec/I0 of the best cell on the unused frequency shall be reported together with Event 2C reporting. 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" with one active cell, cell 2. The Physical Channel reconfiguration message shall be sent to the UE during period T2, after the UE has reported event 2C T3 is defined as the end of the last TTI containing the physical channel reconfiguration message.
