Huawei LTE Compulsory channels

[T_ADD]

Hi, for those guys who do Huawei LTE, can you please state what channels are compulsory and what channels are optional ones. I've marked them in brackets. Are they correct?

For eg., in CDMA, the compulsory channels are PCH, SYNCH, and PICH on DL and ACH on UL. Optional are QPCH, BCCH, DCCH.

LTE CHANNELS:

DL

PBCH (compulsory)
PDSCH (compulsory)
PMCH (optional?)

PDCCH (compulsory)
PCFICH (optional?)
PHICH (optional?)

UL

PUSCH (compulsory)
PUCCH (compulsory)
PRACH (compulsory)
