Subframe structure for the multiplexing of unicast and multicast services

摘要

When data for MBMS is subjected to frequency-division multiplex, FDM, in a long guard interval (GI) subframe, a part of area of a frequency band is limited for use in unicast. Subframe formats of different guard interval lengths are present in a mixed manner. The long GI subframe structure is modified to allow for UE to perform initial cell search with the optimal FFT window irrespective of the multiple GI lengths.
