Problems solved by technology

This method leads to a longer M-BA frame length, which causes the M-BA frame to occupy the air interface for a longer time, so that it is vulnerable to surrounding interference and becomes very unrobust, and the unrobustness of the M-BA frame will cause more serious problems. The retransmission of the MPDU, thereby reducing the communication reliability

Embodiment Construction

[0111] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0112] Usually, when the AP or STA receives the data correctly, it will reply an acknowledgment frame to the sender of the data to tell the sender that the data has been received correctly. In the 802.11 system, there are several different acknowledgment frames as follows.

[0113] Acknowledge (ACK for short) frames are used to confirm non-ag...

Abstract

Provided are a data transmission method, an access point and a station. The method comprises: an access point (AP) sending indication information to at least one station (STA), wherein the indication information is used for indicating the maximum number of traffic identifiers (TIDs) corresponding to a first A-MPDU sent by the STA to the AP in one transmission opportunity (TXOP); the AP receiving at least one MPDU sent by the STA according to the indication information, wherein the at least one MPDU comprises a first MPDU and can further comprise at least one of the following: at least one second A-MPDU, at least one third A-MPDU and at least one S-A-MPDU, so that the at least one MPDU sent by each different STA is aligned; and the AP sending a first M-BA frame to the at least one STA, wherein the first M-BA frame comprises: BA information corresponding to the first A-MPDU. Thus, the reliability of communication is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a data transmission method, access point, and station. Background technique [0002] With the development of Orthogonal Frequency Division Multiple Access (OFDMA for short) technology, the current wireless communication system has been able to support multiple stations (Station, STA for short) to perform data transmission at the same time. When multiple STAs send information to an access point (Access Point, AP for short) through the OFDMA technology, the information may be a control frame, a management frame, or a data frame. The AP may reply acknowledgment information to multiple stations in the form of a Multi-User Block Acknowledgment (Multi-User Block Acknowledgment, M-BA for short) frame. [0003] figure 1 A schematic diagram of data transmission between an AP and an STA provided in the prior art, such as figure 1 As shown, the AP se...
