Abstract:
1. An Orthogonal Frequency Division Multiplexing (OFDM) symbol distributing method for Multimedia Broadcast multicast service Single Frequency Network (MBSFN) sub-frame, the method comprising: according to uniform configuration rules, an OFDM symbol distributing system distributing OFDM symbols in all MBSFN sub-frames bearing transmission of multi-cell transmission Multimedia Broadcast Multicast Service (MBMS) in a MBSFN area; wherein, the MBSFN sub-frames in each cell involved in the transmission of the MBMS in the MBSFN area are uniformly segmented, and then the OFDM symbols of the MBSFN sub-frames in each segment are uniformly configured, wherein the MBSFN sub-frames are segmented according to a size of a Broadcast Control Channel (BCCH) modification period; wherein, an OFDM symbol distributing system distributing OFDM symbols in all MBSFN sub-frames bearing transmission of multi-cell transmission Multimedia Broadcast Multicast Service (MBMS) in a MBSFN area comprises: distributing a first OFDM symbol for non-MBMS in all the MBSFN sub-frames bearing transmission of multi-cell transmission MBMS for each cell in the MBSFN area, or distributing first two OFDM symbols for non-MBMS in all the MBSFN sub-frames bearing transmission of multi-cell transmission MBMS for each cell in the MBSFN area, thus making all the MBSFN sub-frames use same OFDM symbol for the non-MBMS.
