A.5.4d Inter-system Handover from UTRAN FDD to E-UTRAN TDD; Unknown Target Cell
25.1333GPPRelease 17Requirements for support of radio resource management (FDD)TS
A.5.4d.1 Test Purpose and Environment
This test is to verify the requirement for the UTRAN FDD to E-UTRAN TDD handover requirements for the case when the target E-UTRAN FDD cell is unknown as specified in section 5.4b.
The test parameters are given in Table A.5.0P, A.5.0Q and A.5.0R below. The test consists of two successive time periods, with time durations of T1 and T2 respectively. At the start of time duration T1, the UE does not have any timing information of Cell 2. No compressed mode patterns are configured in the test case.
The UTRAN shall send a Handover from UTRAN command with activation time "now" with a new active cell, cell 2. In the E-UTRAN Handover command contained in that message, the IE starting time shall not be included. The RRC HANDOVER FROM UTRAN COMMAND message shall be sent to the UE towards the end of the time period T1. The start of T2 is defined as the end of last TTI containing the handover command.

Note 1: OCNG shall be used such that both cells are fully allocated and a constant total transmitted power spectral density is achieved for all OFDM symbols. Note 2: Interference from other cells and noise sources not specified in the test is assumed to be constant over subcarriers and time and shall be modelled as AWGN of appropriate power for Note 3: RSRP levels have been derived from other parameters for information purposes. They are not settable parameters themselves. |

Note 2
to be fulfilled.A.5.4d.2 Test Requirements
The UE shall start to transmit the PRACH to Cell 2 less than 160 ms from the beginning of time period T2.
The rate of correct handovers observed during repeated tests shall be at least 90%.
NOTE: The handover delay is expressed as: RRC procedure delay + Tinterrupt, where:
Tinterrupt also includes time to detect E-UTRAN TDD cell; see section 5.4b.2.2.
