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.

A scalable satellite data communication system that provides incremental global broadband services using Earth-fixed cells may begin with a limited satellite deployment that initially serves a limited number of Earth-fixed cells. The system has the flexibility to incrementally increase the number of Earth-fixed cells that are served, with minimal constraints on the relative locations of the cells on the Earth, by adding satellites of potentially greater complexity to the system. Backward compatibility with existing user terminals is achieved by maintaining the same satellite communication interface as with the already-deployed satellite constellation. Continuous and / or non-continuous service may be provided to selected Earth-fixed cells. Scheduled non-continuous service is particularly advantageous for bulk data transport services. Satellites may use simple mechanically-steered antennas. Communication links may be handed from one satellite to another when one satellite moves out of range and is no longer able to cover a selected Earth-fixed cell.
