Problems solved by technology

[0005] In the above content, regardless of whether the AP requires the STA to obtain resources for sending data frames through the contention mode or the scheduling mode, the STA needs to continuously listen to each trigger frame sent by the AP, thus causing energy consumption problems

Embodiment approach

[0404] Mode c1. Optionally, when the AP only generates the first indication information in this embodiment of the present invention, before the AP generates the first indication information, the AP sends a source trigger frame to the STA, and the source trigger frame includes the STA allocated by the AP for the STA. The identifier of the source resource used when sending the data frame and the identifier of the STA; if the AP fails to receive the data frame transmitted by the STA within the set time period after sending the source trigger frame, the AP will carry the first indication information in the non-acknowledgment frame, and send a non-acknowledgment frame to the STA.

[0405] In the embodiment of the present invention, when the AP can generate the second indication information, before the AP generates the first indication information, the AP sends a source trigger frame to the STA, and the source trigger frame includes the information allocated by the AP for the STA to ...

Abstract

The embodiments of the present invention relate to the communication field, and in particular to a data transmission method, access point and station in a wireless local area network, which are used to reduce energy consumption during data transmission. In the embodiment of the present invention, when the STA has a data transmission requirement and accepts the data transmission requirement, the AP generates the first indication information; the first indication information includes information used to indicate the first target wake-up time; the first target wake-up time does not Later than the sending time of the target trigger frame that the STA needs to listen to next time, and not earlier than the sending time of the first beacon frame in the beacon frame period to which the target trigger frame belongs; the AP sends the first indication information to the STA, In this way, the STA may not listen to the trigger frame after receiving the first indication information until the first target wakes up, and will not delay the time to listen to the target trigger frame after waking up, thereby reducing the data transmission process. energy consumption.

Description

technical field [0001] The embodiment of the present invention relates to the communication field, and in particular to a data transmission method, access point and station in a wireless local area network. Background technique [0002] Wireless Local Area Network (WLAN for short) technology is a wireless local area network based on the IEEE802.11 standard, which allows the use of 2.4 in the Industrial Scientific Medical (ISM) frequency band that does not require authorization in a local area network environment. GHz or 5GHz radio frequency band for wireless connection, due to its flexible mobility and easy expansion, it has been widely deployed in homes and enterprises. [0003] With the rapid growth of user data, the deployment of WLAN has increased significantly. If the original distributed point coordination based on Carrier Sense Multiple Access with Collision Avoidance (CSMA / CA) is used Function (Distributed Coordination Function, DCF for short) or Enhanced Distribute...
