AI Technical Summary

Problems solved by technology

Multiple first sites use competition to initiate the end-to-end communication site discovery process, resulting in competitive conflicts between multiple first sites
[0005] Especially in a site-intensive scenario, using the existing end-to-end communication site discovery mechanism, since the first site can only discover at most one site at the same time each time it initiates an end-to-end communication site discovery request, the end-to-end communication site The problem of low discovery efficiency is more obvious, and the probability of competition conflicts between multiple first sites that initiate the discovery process is greatly increased

Embodiment 1

[0155] Such as figure 1 As shown, on the side of the first site, the embodiment of the present invention provides an end-to-end communication site discovery method, including:

[0156] S101. The first station obtains a discovery resource from an access point, where the discovery resource is used for end-to-end link transmission;

[0157] S102. The first station broadcasts a discovery trigger frame on the discovery resource. The discovery trigger frame is used to trigger the second station to send a discovery response frame for replying to the discovery trigger frame to the first station. Both the first station and the second station have end-to-end Terminal communication capability;

[0158] S103. The first station receives the discovery response frame sent by the at least one second station, and determines the at least one second station as its own peer-to-peer communication station.

[0159] In this embodiment, the first station acquires discovery resources from the access...

Embodiment 2

[0199] Based on the above embodiments, the present invention also provides a first site, which can adopt figure 1 For the method provided by the corresponding embodiment, refer to Figure 13 As shown, the first station 1300 includes: a transceiver unit 1301 and a processing unit 1302 .

[0200] The transceiver unit 1301 is configured to obtain a discovery resource from the access point, and the discovery resource is used for end-to-end link transmission; broadcast a discovery trigger frame on the discovery resource, and the discovery trigger frame is used to trigger the second station to send a message to the transceiver unit 1301 for Replying the discovery response frame of the discovery trigger frame, both the first station and the second station have end-to-end communication capabilities; receiving the discovery response frame sent by at least one second station;

[0201] The processing unit 1302 is configured to determine at least one second station as a peer-to-peer comm...

Abstract

The present invention provides a device-to-device communication station discovery method, a first station, a second station, and access points so as to improve device-to-device communication station discovery efficiency and avoid contention between multiple stations which respectively initiate a device-to-device communication station discovery process. The method of the present invention comprises: a first station obtains a discovery resource from an access point, the discovery resource being used for the device-to-device link transmission; the first station broadcasts a discovery trigger frame on the discovery resource, the discovery trigger frame being used to trigger the second station to send to the first station a discovery response frame used to respond to the discovery trigger frame, and the first station and the second station both having device-to-device communication capacities; the first station receives the discovery response frame sent by at least one second station, and identifies at least one second station as its own device-to-device communication station.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method for discovering an end-to-end communication station, a first station, a second station and an access point. 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. [0003] The end-to-end communication site discovery process refers to the process of a site discovering a site that can communicate with itself end-to-end. The end-to-end communication site discovery process is necessary for the establishment of an end-to-end communication link and data transmi...
