Problems solved by technology

[0008] Understandably, since the trigger frame can be sent with any contention parameters, and the transmission triggered by the trigger frame involves multiple users, the station cannot determine the maximum time length that the station can occupy the channel in this case according to the existing transmission opportunities. Therefore, fairness in the use of channels between stations cannot be guaranteed

Embodiment 1

[0105] see figure 2 , which shows a multi-user parallel transmission method provided by an embodiment of the present invention, and the method can be applied to a site. The site may be an access point, and correspondingly, the peer end of the site is a non-access site; or both the site and the peer end of the site are sites in a peer-to-peer communication process, which will not be repeated in this embodiment. The method may include:

[0106] S201: The station sends a wireless frame to the opposite end, and obtains the transmission time according to the process of sending the wireless frame;

[0107] Wherein, the transmission time refers to the length of the time period during which the station and the peer exchange frames at the first inter-frame interval and / or the second inter-frame interval;

[0108] S202: The station determines the maximum length of the transmission time according to a preset determination strategy;

[0109] S203: The station exchanges frames with the...

Embodiment 2

[0149] Based on the same technical concept as the foregoing embodiments, in this embodiment, the technical solutions involved in the foregoing embodiments are described in detail through the following specific embodiments.

specific Embodiment 1

[0150] This specific example is based on figure 1 The network architecture shown is described, in which the site is an AP, and the corresponding site peer is a STA, such as image 3 As shown, the process of this specific embodiment may include:

[0151] S301: The AP sends a trigger frame to multiple STAs;

[0152] Understandably, the trigger frame is used to trigger multiple STAs to send uplink multi-user data.

[0153] It should be noted that the specific implementation process of S301 may include: the AP first sends a trigger frame to compete for the channel, and tries to obtain a transmission time, where the transmission time may be the transmission opportunity TXOP in the prior art, or similar to the transmission opportunity It involves the concept of uplink and downlink transmission time periods between the AP and multiple STAs.

[0154] During this transmission time, the AP can exchange frames with multiple STAs using SIFS or PIFS as the inter-frame interval. The shor...

Abstract

The embodiment of the present invention discloses a method, device and system for multi-user parallel transmission; the method may include: a station sends a radio frame to the opposite end, and obtains the transmission time according to the process of sending the radio frame; The set determination strategy determines the maximum length of the transmission time; the station exchanges frames with the opposite end before the maximum length of the transmission time arrives.

Description

technical field [0001] The present invention relates to wireless communication technology, and in particular, to a method, device and system for multi-user parallel transmission. Background technique [0002] With the development of wireless local area network (WLAN, Wireless Local Area Networks) technology and the increasing number of WLAN users, the efficiency of WLAN network is significantly reduced in dense network scenarios. Simply increasing the network transmission rate cannot solve the problem of reduced efficiency. Technology has become a technology to improve network efficiency, which has attracted extensive attention and research. [0003] In the multi-user parallel transmission technology in the prior art, a basic service set (BSS, Basic ServiceSet) of a WLAN includes an access point (AP, Access Point) and a plurality of non-access stations (non-access points) associated with the access point. -APstation). In a WLAN, multiple non-access point sites send data to...
