Normal Frame and Compressed Frame

Compressed mode enables MAHO during hard handover

Gaps in UL and/or DL RF transmissions

Gaps (idle time) can be created by partially speed up data rate

UE performs measurements for MAHO during this idle time. Then UE can search other cell

(W-CDMA or GSM)

There are three method for compressing data

Spreading Factor Reduction

Bit Puncturing

Upper Layer Scheduling

Handover related RF Performance Test Cases

䇭 Following handover related test cases are specified in 3GPP TS

34.121

5.7 Power Setting in uplink compressed mode 䇭(*) (**)

7.7.1 Demodulation of DCH in Inter-Cell Soft Handover (*)

7.7.2 Combining of TPC commands from radio links of different radio link sets (*)

7.9 Downlink compressed modeޓ(*)

8.3.1 FDD/FDD Soft Handover (*)

8.3.2.1 FDD/FDD Hard Handover to intra-frequency cell (*)

8.3.2.2 FDD/FDD Hard Handover to inter-frequency cell (*)

8.3.3 FDD/TDD Handover

8.3.4 Inter-system Handover from UTRAN FDD to GSM

(*) : Agilent Z2195A UMTS-FDD RF Full Conformance System can test these test cases

(**) : Agilent GS-8800 RF Design Verification System will support this test case

Inter-system Handover from UTRAN FDD to GSM without compressed mode is supported by

Agilent E5515C.
