Kind Code:
A1
Abstract:
A service multiplexing method of MBMS system includes: in the MBMS system of OFDM
and in the region area which is overlapped by at least two MBMS services, processing
the two MBMS services with TDM; based on service coverage area being in direct
proportion to the inserted CP length in each OFDM symbol in TDM time slots which
bear MBMS service, and according to size relation of coverage area between at
