    Abstract: 一种无线通信系统,其中接入点(AP)发送下行链路信号给一个或多个用户单元(SU)接收,而用户单元(SU)发送上行链路信号给AP接收。来自接入点(AP)的下行链路信号在预定的时刻携带同步突发(2),和在所述同步突发之间交织的帧内包含的数据。每个同步突发都包括一个指向后续下行链路帧的开始的偏移指示符(4)。

    Abstract: Techniques for acknowledging communications from multiple devices are described herein. For example, a device may broadcast a group acknowledgement message indicating that communications from multiple devices have been received by the device. Each acknowledgement in the group acknowledgement message may include a device identifier for a device that sent a communication (e.g., a Medium Access Control (MAC) address of the device, a hash of the MAC address of the device, etc.) and a communication identifier for the communication (e.g., a sequence number of the communication, a Cyclic Redundancy Check (CRC) code for the communication, etc.).

    Abstract: A method for retransmitting data includes a transmitter receiving a retry request, where the retry request includes a sequence number of a first to-be-retransmitted flit. The transmitter reads data in a retry buffer based on the sequence number of the first to-be-retransmitted flit and retransmits the data, where the retry buffer includes flits of at least two types of data packets, and retransmission manners of the at least two types of data packets are different.
