ABSTRACT:
Congestion control provides congestion control for one or more shared resources in a wireless communication network. In one exemplary embodiment, a congestion controller manages congestion of shared packet data channels by under-serving selected ones of the data connections sharing the packet data channel. Such selective under-serving may be effected by biasing scheduling of service on the packet data channel toward maximum throughput scheduling such that connections associated with poor radio conditions are naturally under-served. Further, the controller may manage congestion of other shared resources, such as shared transmit power resources, wherein congestion of the shared power resource is managed by under-allocating transmit power to selected ones of the connections. Congestion is sensed, for example, by monitoring transmit buffer occupancy levels, and/or reserve power levels. In either case, congestion relief may be amplified where operation of the controller “triggers” flow control on the intentionally under-served ones of the active data connections.
