Problems solved by technology

Stations with end-to-end communication capabilities and stations without end-to-end communication capabilities can participate in channel competition after determining that the station is idle, resulting in a certain amount of competition overhead during channel competition
[0004] Especially in scenarios with dense sites, the demand for end-to-end communication and traditional uplink / downlink communication will be relatively large, which will greatly increase the competition overhead of sites participating in channel competition and affect system throughput.

Abstract

The invention provides an end-to-end communication method to reduce the channel competition overhead under the end-to-end communication and improve the system throughput. The method includes: the access point determines a time window for peer-to-peer communication between stations; the access point sends a downlink frame including the time window, and the downlink frame is used to indicate a station with peer-to-peer communication capability The stations communicate end-to-end within said time window.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to an end-to-end communication method, an access point and a first station. Background technique [0002] End-to-end (Device-to-Deceive, D2D) communication technology is a technology that allows direct communication between terminals. It can increase the spectrum efficiency of the communication system, reduce the transmission power of the terminal, and solve the spectrum resource problem of the wireless communication system to a certain extent. The lack of problems can significantly improve the performance of the entire network system. A link used for end-to-end communication between two sites is called a site-to-site communication link (Direct STA-to-STA Link, DSSL). [0003] The existing end-to-end communication adopts a carrier sense multiple access (Carrier Sense Multiple Access, CSMA) mechanism, the core of which is carrier sense. All stations participate in chan...
