Direct link scheduling method, access point and terminal device

Abstract

The embodiment of the invention discloses a direct link scheduling method, an access point and terminal devices. The method of the embodiment of the invention comprises that the access point carries out multicast or broadcast to the information of multiple direct links participating in a subsequent direct link scheduled period; in the direct link scheduling period, the access point obtains voice test results sent by the both-side terminal devices of the multiple direct links, channel resources are respectively distributed to the multiple direct links according to the voice test results; the subchannels in the channel resources of every direct link do not comprise unusable subchannels or are selected from usable subchannels; and / or the subchannels or the transmission time in the channel resources of two mutually interfered direct links are different; the access point sends the information of the distributed channel resources to the both-side terminal devices of the multiple direct links. According to the embodiment of the invention, channel competition between different direct links is avoided, and the probability of generating conflict resulted from the channel competition is reduced.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a direct link scheduling method, an access point and a terminal device. Background technique [0002] In the WiFi (Wireless Fidelity, Wireless Fidelity) technical standard "IEEE802.11-2012", a direct communication method DLS (Direct-Link Setup, direct link establishment), the initiator STA (Station, refers to the terminal device in this article) )1 sends a management message requesting to establish a direct link to an access point (AccessPoint, AP), and the AP forwards the request message to STA2, and STA2 can establish a direct link with STA1 after accepting the request. After the direct link is established, when the above two STAs communicate with each other, the message can be directly sent to the other party through the air interface (English: air interface or wireless interface), without forwarding through the AP. In this way, compared to when STA1 sends a pie...

Problems solved by technology

The latest standard IEEE802.11ax uses direct connection technology to improve system throughput in some dense user scenarios. However, the existing standard does not effectively manage the direct connection link. To compete for the channel by itself, which is not conducive to improving the utilization efficiency of wireless resources
