A.5.3b TDD to E-UTRA TDD Handover
25.1233GPPRelease 17Requirements for support of radio resource management (TDD)TS
A.5.3b.1 Test Purpose and Environment
A.5.3b.1.1 3.84 Mcps TDD option
A.5.3b.1.2 1.28 Mcps TDD option
This test is to verify the requirement for UTRAN TDD to E-UTRAN TDD handover requirements specified in section 5.3b.
The test scenario comprises of 1 UTRA TDD cell and 1 E-UTRA TDD cell as given in tables Table A.5.3b.1.2-1, Table A.5.3b.1.2-2, and Table A.5.3b.1.2-3. Idle interval of 80ms period as defined in TS25.331 is configured before T2 begins to enable E-UTRAN monitoring.
The test consists of three successive time periods, with time durations of T1, T2 and T3 respectively.
A RRC message implying handover shall be sent to the UE during period T2, after the UE has reported Event 3a. The end of the last TTI containing handover message is begin of T3 duration.
