10.2 Demodulation of MTCH
25.1023GPPRelease 17TSUser Equipment (UE) radio transmission and reception (TDD)
The receive characteristic of the MTCH is determined by RLC SDU error rate (RLC SDU ER). RLC SDU ER is specified for each individual data rate of the MTCH. The requirement is valid for all RRC states for which the UE has capabilities for MBMS.
