A method of scheduling a plurality of subscriber equipment based on sets of channel conditions and calculated power allocations for downlink channels of an air interface of a wireless communication system to satisfy a desired system requirement. A set of subscriber requesting access to the communication system or being provided access to the communication are selected by a scheduler based on their channel conditions and power allocation calculation. The scheduler then schedules the selected set of subscribers to achieve the desired system requirement whereby the subscribers simultaneously receive information from a multiple of antennas which are typically located at a base station.

Method of allocating power for the simultaneous downlink conveyance of information between multiple antennas and multiple destinations

A method of providing a plurality of schedulers for independently scheduling multiple subscribers to increase the capacity and/or throughput of an HDR wireless communication system. Each scheduler is associated with base station equipment and an antenna that receive channel conditions on which the scheduling of subscribers are based.

Method for multi-antenna scheduling of HDR wireless communication systems

A wireless communication system () includes using multiple antennas () for simultaneous transmissions to multiple mobile stations (). A distributed multiple antenna scheduling (DMAS) technique includes selecting a plurality of mobile stations for at least receiving simultaneous transmissions on at least one selected subcarrier from within a carrier bandwidth having orthogonal frequency division multiplexing (OFDM). In a disclosed example, a plurality of mobile stations are selected for each subcarrier within the carrier bandwidth. A disclosed example includes grouping subcarriers together into subsets to reduce computation complexity for determining which mobile stations to select for the simultaneous transmission.

Distributed multiple antenna scheduling for wireless packet data communication system using OFDM

The present invention provides a method for reducing transmitted energy based on early decoding. The method includes accessing a first portion of a block including a plurality of symbols indicative of an encoded message. The first portion has been transmitted at a first transmission power and having less than all of the plurality of symbols. The method also includes attempting to decode the encoded message using the first portion of the block, determining whether the encoded message was decoded, and providing an indication of a second transmission power in response to determining that the encoded message was decoded.

Method and apparatus for reducing transmitted energy in power-controlled systems based on early decoding

A method of transmitting information over a feed back channel of a communication system that has multiple antenna systems is provided. Long term channel condition information is obtained from received measured and/or calculated channel parameter values. The obtained long term channel condition information is arranged in a particular manner and transmitted over a defined time period during which the long term channel condition information varies relatively slowly. Because the long term information remains relatively constant for one or more defined time periods, the amount of bandwidth needed to communicate this value is small because it need only be communicated occasionally. Thus only a small bandwidth needs to be allocated for transmitting this long term information.

Method for improved performance and reduced bandwidth channel state information feedback in communication systems

A wireless data communication system simultaneously transmits data signals from more than one antenna with a deterministic, time-dependent phase difference between the signals. In one example, more than one antenna transmits the same data signal with a phase difference between the transmitted signals. In another example multiple users' data signals are simultaneously transmitted using a corresponding plurality of beams that each use at least two transmitting antennas. Transmissions to multiple users on a shared packet data channel can be scheduled at the same time. In one example, the phase difference is periodic and the beams are orthogonal to maximize system throughput even when one or more users is stationary or slowly moving.

Multiple antenna transmissions with deterministic phase differences

A flexible communications systems provides users with additional communication channels without requiring additional transmitters or receivers by using variable rate Walsh coding. Additionally, the assignment of these additional communication channels is easily managed at the base station by monitoring data backlog and receiver error rates.
