7.1.4.1 Control of CPCH transmissions for FDD
7.1.4.1.1 Definition and applicability
All UEs which support CPCH.
7.1.4.1.2 Conformance requirement
1. If counter M is not less than N_access_fails, the UE shall execute an access failure error procedure and the CPCH access procedure ends.
2. If the sum of the Frame Count Transmitted counter plus the number of frames in the next TTI is larger than NF_max, the UE shall exit the CPCH transmission procedure.
3. If the CSICH information indicates no PCPCH is available, the UE shall not attempt CPCH access.
4. If the CPCH Persistency levels are all set to 8, the UE shall not attempt CPCH access.
5. If the SS issues an immediate Emergency Stop command in the DL-DPCCH for CPCH, the UE shall abort CPCH access.
