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 comprises a plurality of RUs, and the 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: The method includes: receiving, by a second transmit end, policy information sent by a first transmit end, where the second transmit end belongs to a second BSS, the first transmit end is a transmit end that is in a first basis service set and that transmits data by using a first link, and the policy information is used to indicate a condition that the second transmit end needs to satisfy to transmit data by using a second link, or used to indicate whether the second transmit end is allowed to transmit data by using a second link; and determining, by the second transmit end based on the policy information, whether to transmit data by using the second link. According to the wireless communication method, a spatial reuse transmission policy can be adjusted dynamically based on an actual situation of a current network. This improves a system throughput.
