Abstract: The present disclosure suggests to expand and improve the method of utilizing channel resources in the 802.11be standard by allowing the use of multiple and non-contiguous portions of a channel. Supporting multiple resource units (MRUs) and non-contiguous resource units (RUs) improves the channel utilization by making it more efficient due to enhancing the capability of leveraging the channel selectivity. To this end, a wireless network device for resource allocation is provided and configured to define a non-contiguous MRU in the bandwidth of the channel. The channel includes a plurality of RUs, and the non-contiguous MRU is defined based on non-punctured RUs after puncturing one or more of the RUs of the channel, and/or is defined by aggregating two or more non-adjacent RUs of the channel.

Abstract: This application provides a communication method and apparatus that allow retransmitted MPDUs with different retransmission versions (RVs) to be transmitted in a same transmission process. The communication method and apparatus may be applied to a data retransmission process between any two nodes in a Wi-Fi system. In the method, when a PPDU sent by a first node includes one or more retransmitted MPDUs, the first node may include RV indication information in the PPDU to indicate an RV of each retransmitted MPDU, so that a second node can properly receive each retransmitted MPDU based on the RV indication information.
