摘要： A method and system for using one H-ARQ process in communication systems having a Multiple Input Multiple Output antenna system. Information to be transmitted is first coded using a particular coding scheme and having a particular base coding rate. The coded information is then divided into groups of sub-blocks of coded information. Each group of sub-blocks of coded information contains one or more sub-blocks where the number of sub-blocks in a group is determined from current channel conditions of an antenna through which the group is to be transmitted. The groups are then rate matched and modulated based on the current channel conditions and transmitted through one or more antennas. For any retransmissions, the same coded information is used and is divided into groups of sub-blocks of coded information where at least one new group is associated with one of the plurality of antennas; the number of sub-blocks of coded information in a new group is based on current channel conditions experienced by the associated one antenna. Each group of sub-blocks is again rate matched and modulated before transmission. The rate matching and modulation parameters for any group of sub-blocks are determined by the channel conditions of the antenna through which that particular group is to be transmitted.

摘要： A method of data communication. The method includes transmitting a control message identifying missing data as lost by the transmitter prior to the expiration of a timer. The missing data may include at least one data packet such that the control message identifies the at least one missing data packet. The control message may include a field and/or an acknowledge sequence number for identifying the missing data packet. The control message also may include a packet data unit having a dummy payload and/or a zero payload. The control message communicates to the receiver that the transmitter has aborted the transmission and/or retransmission of the one or more missing data packets. The control message may be communicated to the receiver over the same data channel used for transmitting the data packets, or alternatively, a wholly different channel than the data channel.
