Claim of US Patent No. 10,798,717

1. A wireless communication method, wherein the method is applied to a wireless local area network, the wireless local area network comprises a first basic service set (BSS) and a second BSS, and a coverage area of the first BSS partially overlaps with a coverage area of the second BSS, and the method comprises:receiving, by a second transmit end, policy information sent by a first transmit end, wherein the second transmit end belongs to the second BSS, the first transmit end is a transmit end that is in the first BSS and that transmits data by using a first link, 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 the policy information is used to indicate whether the second transmit end is allowed to transmit data by using a second link, time domain resources corresponding to the second link are partially the same as time domain resources corresponding to the first link, and frequency domain resources corresponding to the second link are partially or completely the same as frequency domain resources corresponding to the first link, wherein a maximum allowed interference value is determined by the first transmit end based on an energy value of an input signal of a receive end of the first link and a lowest signal-to-noise ratio required for transmitting information by using the first link, wherein the input signal is a signal of the first transmit end that is received by the receive end of the first link from the second BSS and the first transmit end determines the maximum allowed interference value based on a margin used to improve robustness of spatial reuse transmission, wherein the policy information comprises indication information of the maximum allowed interference value that is the maximum interference value of a signal from the second BSS that is allowed by the receive end of the first link; and
determining, by the second transmit end based on the policy information, whether to transmit data by using the second link.
