A.5.3d.1 Test Purpose and Environment

A.5.3d.1.1 3.84 Mcps TDD option

A.5.3d.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 when the target E-UTRAN cell is unknown.

The test scenario comprises of 1 UTRA TDD cell and 1 E-UTRA TDD cell as given in tables A.5.3d.1.2-1, A.5.3d.1.2-2, and A.5.3d.1.2-3. No scheduled idle interval is configured in the test case.

The test consists of two successive time periods, with time durations of T1 and T2 respectively. During time duration T1, a RRC HANDOVER FROM UTRAN COMMAND message shall be sent to the UE with activation time "now" with a new active E-UTRA TDD cell, cell2. The end of the last TTI containing handover message is the beginning of T2 duration. At the start of time duration T2, the UE does not have any timing information of Cell 2.

Note 1: OCNG shall be used such that cell is fully allocated and a constant total transmitted power spectral density is achieved for all OFDM symbols.

Note 2: RSRP levels have been derived from other parameters for information purposes. They are not settable parameters themselves.
