R4-021485 Fading test case for cell identification requirement (Nokia)

It is noted that different speeds should be considered also. Edgar Fernandes (Motorola) pointed out also that the 800ms figure coming from the general requirements might not be applicable to this particular situation, non-general values should be considered. Mitsubishi commented that some frequency error (ppm drift) has to be introduced in this test case to reflect realistic scenario where the 2 cells have not the same frequency sources and Doppler shifts.

R4-021580 On cell identification in multipath fading conditions (Siemens)

Information paper. It was felt that no problem is identified so far with regards to the intra-frequency cell measurements.

R4-021664 Simulation assumptions for inter FDD cell identification with compressed mode (Mitsubishi)

Siemens thanked Mitsubishi and wondered about the RF noise factor, noticed a typo in the ppm equation and insisted onto the minimum gap density which has to be set a bit lower. Mitsubishi clarified that the RF noise factor was taken for inclusion on top of the implementation margin. Nokia noticed that consideration of these assumptions needs more time, especially from network side. Nokia also commented that the proposed simulation assumptions include very implementation related parameters and there are also other means but simulations to evaluate the performance of the UE. Mitsubishi requested a deadline for the next meeting, particularly:

- What is the lower bound of the gap density into the core requirements in Release 99?

- What are the test cases to be included in Release 5 ?

It was agreed to further discuss this onto e-mail reflector.

Chairman concluded that, as Release 99 may be impacted by this topic, this will be reported to RAN plenary.
