BCCH,CCCH,DCCH、DTCH 都映射到 DL-SCH 再映射到 PDSCH,UE是如何区分这三者呢?
我知道用SI-RNTI加扰的PDCCH对应BCCH,那如何区DCCH,DTCH,它们都是用C-RNTI加扰的吧

possibly by the LCID field of MAC header
00000 CCCH
00001-01010 Identity of the logical channel
so LCID = 0 means CCCH(SRB0)
LCID = 1 means DCCH(SRB1)
LCID = 2 means DCCH(SRB2)
all other LCID corresponding to DTCH(DRB)
00000 CCCH
00001-01010 Identity of the logical channel
so LCID = 0 means CCCH(SRB0)
LCID = 1 means DCCH(SRB1)
LCID = 2 means DCCH(SRB2)
all other LCID corresponding to DTCH(DRB)
非常感谢,向大牛学习!
