Wireless communication method and apparatus

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:

• determining, by a first transmit end, policy information, wherein the first transmit end is a transmit end that is in the first BSS and transmits data by using a first link, the policy information is used to indicate a condition that a second transmit end needs to satisfy to transmit data by using a second link or the policy information is used to indicate whether a second transmit end is allowed to transmit data by using the second link, the second transmit end belongs to the second BSS, 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 the policy information comprises indication information of a maximum allowed interference value;
• determining the maximum allowed interference value based on an energy value of an input signal of a receive end of the first link, wherein the first transmit end determines the maximum allowed interference value of the receive end of the first link based on a depth gap value, wherein the depth gap value is a difference between a first interference value and a second interference value, the first interference value is an energy value of a signal from the second BSS that is received by the receive end of the first link, and the second interference value is an energy value of a signal from the second BSS that is received by a device, in the first BSS, nearest to the second BSS;
• and
• sending, by the first transmit end, the policy information.

A wireless communications apparatus, the apparatus being configured in a wireless local area network, the wireless local area network comprising 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, the apparatus comprising:

• a transceiver configured to receive policy information sent by a first transmit end, wherein the first transmit end is a transmit end that is in the first BSS and transmits data by using a first link, the policy information is used to indicate a condition that a 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, the second transmit end belonging to the second BSS, 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 the policy information comprises indication information of a maximum allowed interference value, wherein the maximum allowed interference value is determined based on an energy value of an input signal of a receive end of the first link, wherein the first transmit end determines the maximum allowed interference value of the receive end of the first link based on a depth gap value, wherein the depth gap value is a difference between a first interference value and a second interference value, the first interference value is an energy value of a signal from the second BSS that is received by the receive end of the first link, and the second interference value is an energy value of a signal from the second BSS, in the first BSS, nearest to the second BSS;
• and
• a processor configured to determine, based on the policy information received by the transceiver, whether to perform transmission.
