Abstract
A novel and useful apparatus for and method of multicast and broadcast service (MBS) macro-diversity based information processing for use in MBS enabled wireless communication systems. MBS allocations and transmissions from base stations are not coordinated and independent of each other. The characteristics of the MBS signal, such as waveform, modulation, timing and frequency domain, used for transmissions in one or more MBS zones by a base station are uncoordinated and unsynchronized with respect to transmissions in other base stations or MBS zones. They all, however, contain the same information content and relate to the same CID (MCID and/or SA). The MS, using multiple detection techniques, uses time and frequency diversity reception techniques to combine MBS transmissions received from multiple base stations. Base stations and/or the network inform mobile stations of whether or not uncoordinated MBS data transmission is supported on the network via a TLV transmitted during the MBS connection setup process. If supported, mobile stations can receive multiple MBS data signals, combining them to generate a single MBS data output stream.
