Patent ID: 7058407

Claim:
A controller for adapting a diversity transmission mode to provide point-to-multipoint transmission diversity of packet data derived from an information stream in a fixed network of a wireless data communication system, the controller comprising: at least one communication interface for receiving the information stream and for communicating with a base station of the communication system; and a processor coupled to the at least one communication interface for processing the information stream and for controlling the base station; wherein the processor is programmed to transmit an indication that a diversity transmission of the information stream is available; and wherein, when predetermined capabilities of a user equipment (UE) and the fixed network are sufficient to allow soft combining of a primary transmission and a diversity transmission of bits of the information stream in the UE, the processor is further programmed to: transmit the primary and diversity transmissions in a manner that facilitates soft combining in the UE, and transmit a group identity of the information stream to indicate that the information stream is in the primary and diversity transmissions.
