摘要： A wireless communication system (20) includes a wireless network (30) that selectively modifies an aggregation of voice over internet protocol wireless transmissions. In one example, a mobile station geometry provides an indication whether modification of the aggregation is desirable. For example, a mobile station with a better geometry allows for a higher level of aggregation. Another disclosed example includes determining a current cell load condition and increasing the amount of aggregation and the level of aggregation as cell load conditions increase. Another disclosed technique includes staggering the scheduling of aggregated packets to avoid delays at a scheduler. One or more of the disclosed techniques may be used to efficiently transmit voice over internet protocol communications.

摘要： 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.

摘要： A wireless communication system (20) includes using multiple antennas (30, 32) for simultaneous transmissions to multiple mobile stations (24, 26). 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.
