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; wherein the method comprises: receiving (S210), 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, wherein the policy information comprises indication information of a maximum allowed interference value, wherein the maximum allowed interference value is a maximum interference value that is of a signal from the second BSS and that is allowed by a first receive end, and the first receive end is a receive end of the 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 the policy information is used to indicate whether the second transmit end is allowed to transmit data by using the 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, and determining (S220), by the second transmit end, whether to transmit data by using the second link; characterised in that : the maximum allowed interference value is determined by the first transmit end based on an energy power of an input signal of the first 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 first receive end of the link. receiving (S210), 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, wherein the policy information comprises indication information of a maximum allowed interference value, wherein the maximum allowed interference value is a maximum interference value that is of a signal from the second BSS and that is allowed by a first receive end, and the first receive end is a receive end of the 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 the policy information is used to indicate whether the second transmit end is allowed to transmit data by using the 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, and determining (S220), by the second transmit end, whether to transmit data by using the second link; characterised in that : the maximum allowed interference value is determined by the first transmit end based on an energy power of an input signal of the first 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 first receive end of the link. <EOS>
