Abstract: The present invention provides a method and device for acquiring and transmitting data by an STA in a wireless local area network. The method includes: transmitting, by the STA, a PS-Poll, and receiving downlink data returned by the AP upon receipt of the PS-Poll, in a reserved time period within a current beacon interval according to a TIM contained in a beacon, after learning that the AP has the downlink data of the STA according to the received beacon, wherein the reserved time period is a period of time interval within the beacon interval; retransmitting, by the STA, the PS-Poll after the reserved time period to acquire the downlink data, if the STA can not successfully receive the downlink data within the reserved time period. Through the above solution, a mechanism is provided to address a situation that unsuccessful receiving/transmission of data can not be handled.

Abstract: Embodiments of the present application provide an interference processing method and device. The method includes: a first access point (AP) receiving a frame sent by a second AP, the frame carrying downlink data load of the second AP, and intra-frequency interference existing between the first AP and the second AP; and the first AP adjusting, according to downlink data load of the first AP and the downlink data load of the second AP, a channel bandwidth used for performing data communication with a station (STA), so as to reduce the probability that the first AP and the second AP transmits data by using same channel. By using the method and the device for dynamically adjusting a bandwidth, intra-frequency interference of devices in OBSS can be reduced.

Abstract: Embodiments of the present invention provide a method and apparatus for receiving fragments as well as a method and apparatus for transmitting fragments. The method for receiving fragments includes: receiving a group of fragments from a transmitter through a first channel, where the transmitter suspend transmitting a next group of fragments after the group of fragments is transmitted; and transmitting one or a plurality of first acknowledgement messages to the transmitter through the first channel immediately after the group of fragments are received. According to embodiments of the present invention, the acknowledgement messages may be immediately transmitted to the transmitter through a current channel after one group of fragments are received through the current channel, thereby avoiding the delay of a fragment receiving and transmitting process, which is caused by the competition and occupation of the channel by other nodes, and thus improving transmission efficiency.
