Provided are a method and device for sending and receiving a data frame. The method for sending a data frame comprises: a first access point receives a first interference power parameter fed back by an associated station of a first access point, and receives a second interference power parameter sent by a second access point; if it is determined that a channel where the first access point works is currently occupied by the second access point, determining transmitting power of a station to be scheduled and the first access point to the station to be scheduled, and sending scheduling indication signaling at the determined transmitting power, and receiving scheduling indication response signaling sent by a schedulable station; sending a data frame to a schedulable station at transmitting power corresponding to the schedulable station among the determined transmitting power. The present invention can realize simultaneous downlink transmission of multiple first access points in regions having interference to each other, improves the utilization of network spectrum resources without additional signaling overhead, and at the same time, ensures real-time power control. |
