摘要： Systems and methods of MIMO wireless communication system with partial feedback are disclosed. In one embodiment, a base station estimates the channel matrices of the K mobile units and transmits an index value corresponding to each of the estimated channel matrix. Each mobile unit selects a power control matrix and beam-forming matrix based on the received index value and transmits its data stream to the base station using the selected power control and beam-forming matrix. A method for generating the sets of power control matrices, beam-forming matrices, and partitions of the channel matrix space is disclosed.

摘要： A method of processing, in parallel fashion, messages from a User Equipment (UE) in soft handoff with a plurality of base stations of a wireless communication system. Measurement Messages from the User Equipment are received and stored in a message buffer for a defined period of time. Later arriving messages replace previous messages during the defined period of time. When the defined period of time elapses, the latest stored message is processed in parallel fashion in a processing pipeline with other messages for the UE and other UEs. The latest message is processed by first converting it to soft handoff actions and inserting such actions into a processing pipeline. A conflict table is generated during the parallel processing of the soft handoff actions to avoid the processing of messages that conflict with each other. Conflicting messages are put into a pending state and remain in such state until they are canceled by subsequent messages or the conflict no longer exists.

摘要： Systems and methods which control communications in a carrier sense multiple access environment to provide a balance between communication sensitivity and transmission availability are shown. Adaptive interference control techniques of embodiments operate to determine a media error time metric representing the time associated with receiving interfering signals. The media error time metric of embodiments is used to adjust operation of various network systems in order to adjust communication sensitivity and/or transmission availability. Desensitizing thresholds and sensitizing thresholds may be used to define operating boundaries, such that desensitizing thresholds are used to control network desensitize actions which result in decreased error times and sensitizing thresholds are used to control network sensitizing actions which result in increased error times. Error time metrics and corresponding desensitizing and sensitizing thresholds may be utilized with respect to a plurality of radios. Embodiments provide for adjustment of control parameters based upon historical operation.
