Embodiment Construction

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0046] see figure 1 A schematic flowchart of a method for coordinating an unlicensed channel disclosed by an embodiment of the present invention is shown.

[0047] Depend on figure 1 It can be seen that the method includes:

[0048] S11: Obtain a list of neighbor relations of nodes to be coordinated.

[0049] In this embodiment, firstly, each competing node (Wi-Fi AP and LAA base station) establishes a neighbor relationship list in advance, so...

Abstract

The invention discloses an unlicensed channel coordination method and device. According to the method, a neighbor relation list of to-be-coordinated nodes is obtained, so that the channel competition parameters of each adjacent node and each to-be-coordinate node in the neighbor relation list are obtained, and thus the back-off time of the adjacent nodes and the to-be-coordinate nodes is computed. When the adjacent node having the same back-off value time as the to-be-coordinate node is determined to exist in the neighbor relation list, all nodes with the same back-off time are controlled to modify the respective back-off values, so that collision of the nodes is avoided when data is sent.

Description

technical field [0001] The present application relates to the technical field of communications, and more specifically, to an authorization-free channel coordination method and device. Background technique [0002] With the rapid development of mobile smart devices, the rapid emergence of high-definition multimedia streaming services, and the penetration of the Internet into all walks of life, etc., the traffic of mobile data services has exploded, and the existing licensed frequency bands are not enough to provide sufficient network capacity. Meet user needs. Offloading data services to unlicensed frequency bands (such as 5GHz) can relieve network pressure. How to use unlicensed spectrum resources with the assistance of licensed spectrum has become one of the important research topics of 3GPP. [0003] Existing unlicensed access technologies, such as Wi-Fi technology and LAA (Licensed Assisted Access, Authorized Assisted Access) technology, use unlicensed spectrum based on...
