METHOD AND SYSTEM FOR SOFT HANDOFF IN MOBILE BROADBAND SYSTEMS
First Claim
1. A method for communication in a mobile broadband system in which a mobile device coordinates communication with a plurality of base station transceiver systems by reserving communication resources from the plurality of base station transceiver systems, the method comprising:
- transmitting a resource request to at least one of the plurality of base station transceiver systems;
receiving resource availability data from the at least one of the plurality of base station transceiver systems; and
selecting a common set of available resources for transmission based on the received resource availability data.

Abstract
The present invention provides a method and system for facilitating efficient handoff and data throughput in mobile broadband communication systems. Methods implemented by a system constructed in accordance with the principles of the present invention include selectively enabled soft handoff, performing Layer 2 bearer functions at the base station and using the mobile device to coordinate soft handoff and interference avoidance without the need for a centralized coordination function.
