Abstract: In a wireline or wireless telecommunications system or data network, which employs a Selective Repeat Automatic Repeat Request (ARQ) to convey data packet reception status for a sequence of data packets grouped together into a number of blocks of data packets, partial bit mapping is employed to improve efficiency, particularly with respect to bandwidth. This may be accomplished, more specifically, by including in the ARQ message that is sent from the receiver to the sender, a number of partial bitmaps, along with a corresponding number of bitmap block numbers, where a first bitmap block number identifies a particular one of the blocks of data packets and the corresponding bitmap defines the reception status of the data packets in that block. Each of the remaining bitmap block numbers identify an additional block of data packets relative to the first block of data packets. Accordingly, the remaining bitmap block numbers require fewer bits to identify their corresponding data packet blocks.
Abstract translation: 在有线或无线电信系统或数据网络中，其使用选择性重复自动重传请求（ARQ）来将分组在一起的数据分组序列的数据分组接收状态传送到多个数据分组块，采用部分比特映射 以提高效率，特别是在带宽方面。 这可以更具体地通过将从接收器发送到发送器的ARQ消息中包括多个部分位图以及对应数量的位图块号码来实现，其中第一位图块号码标识特定的一个 的数据分组块和相应的位图定义了该块中的数据分组的接收状态。 剩余的位图块号码中的每一个标识相对于第一数据包块的附加数据包块。 因此，剩余的位图块号需要较少的比特来标识它们对应的数据分组块。
