    摘要: A method in a communication system (100) includes transmitting from a source user (101) a first data packet (111) over a first time frame (121) having a finite time period (131), transmitting from source user (101) a second data packet (112) over a second time frame (122) immediately subsequent to first time frame (121), detecting an acknowledgment of acceptable reception of data packet associated with either first or said second data packets (111 and 112), repeating transmission of first and second data packets (111 and 112) in a sequence of first and second time frames (121 and 122) in a time frame sequence (190) until the detection.

    摘要: A base station (101) will request the transmission of quality information from a particular remote stations (102, 103) only when data is queued to be transmitted to the remote stations. Once a remote station begins the transmission of channel quality information, the transmission of such information continues until the data transmission is successfully delivered to the remote station. The base station receives the channel quality information and adjusts the modulation and coding of the remote stations accordingly. Where data is transmitted simultaneously to a plurality of remote stations, a set of queues (303) for the multiple remote stations is maintained, and based on queue status, a channel quality request messages is sent to a sub-set of remote stations with data queued.

    摘要: A method and apparatus for performing H-ARQ transmission is described herein. Bits received on a first transmission are stored and combined with the bits received on later transmissions thereby increasing the likelihood of a correct decoding on later transmissions. Additionally, a plurality of coding schemes (e.g., Convolutional Codes, Block Turbo Codes, Convolutional Turbo Codes, Low Density Party Check Codes, . . . , etc.) are utilized, with an information element being reserved to signal what form of H-ARQ is being utilized.

    摘要: A method and apparatus for control channel transmission and reception is provided herein. In particular, the use of a partitioned and structured control channel is provided that leverages the benefits of common control while maintaining favorable aspects of dedicated control. During operation, control information is distributed over a number of partitions (201). Each Pi is encoded (607) with monotonically non-increasing reliability level. Control information for a given remote unit can be distributed on one or several partitions, from P1 to Pk, where Pk is encoded with the lowest reliability level that can be decodable by the remote unit at an acceptable error rate.
