Document Type and Number:
WIPO Patent Application WO/2022/144006
Kind Code:
A1
Abstract:
Provided are a method and apparatus for sending an acknowledgement frame, a station, and a computer-readable storage medium. The method comprises: receiving a data frame sent by a first access point, and according to the data frame, calculating the lowest transmit power of a local station sending an acknowledgement frame; using the maximum transmit power of a first station at a predetermined rate as initial transmit power; invoking a pre-established overlapping basic service set highest transmit power queue, the overlapping basic service set highest transmit power queue being the highest transmit power set which does not affect packet reception by a second station and which is obtained by calculation; traversing the overlapping basic service set highest transmit power allowed in the pre-established overlapping basic service set highest transmit power queue in sequence; and on the basis of being greater than or equal to the lowest transmit power, obtaining the minimum value among the initial transmit power and the highest transmit powers, and determining same to be the final transmit power to send the acknowledgement frame. In the present application, interference to packet reception by a node in an overlapping basic service set is reduced, and communication quality in a high-density region is improved.
