A parameter configuration method of listen first and talk based on interference level

Abstract

The present invention relates to a listen-before-talk parameter configuration method based on interference levels, which includes: step S1, a base station sends an interference level configuration command to a terminal device, wherein the interference level configuration command includes thresholds corresponding to different interference levels information; step S2, the terminal device sets or updates the first mapping table according to the threshold information corresponding to different interference levels included in the interference level configuration command; step S3, the terminal device sets or updates the first mapping table in a subband Before performing data transmission on the Internet, evaluate the interference level of the subband according to the first mapping table; step S4, the terminal device selects the corresponding LBT parameter in the second mapping table according to the interference level of the subband, And use the LBT parameter to transmit data on the sub-band. The invention improves the data transmission efficiency of the whole network and reduces the interference with different systems.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a parameter configuration method of listen first and talk based on interference level. Background technique [0002] With the rapid development of wireless mobile communication technology, the demand for wireless communication in all walks of life is increasing. However, due to the limited available wireless spectrum resources, multiple communication systems and multiple communication systems coexist for a long time in the same frequency band. For example, many frequency points in the 223-235MHz frequency band are irregularly occupied by multiple departments, including: the power department is used to deploy power wireless communication systems to promote the construction of smart grids; the Ministry of Geology and Mineral Resources is used to remotely measure water levels instrument; the Ministry of Water Resources for hydrological telemetry; the Ministry of Light Industry f...

Problems solved by technology

[0005] However, the 3GPP standard does not include the definition of interference level and interference level configuration command, and the method of LBT parameter selection based on interference level

At the same time, the existing LBT parameter optimization scheme mainly adjusts LBT parameters based on the quality of service priority, but does not involve the LBT parameter optimization method based on the interference level, and the design of the interference level configuration command between the base station and the terminal equipment

For example, a method for exchanging LBT parameters between sites is proposed in the patent application "Listen First, Talk Before Parameter Processing Method, Competition Window Adjustment Method and Device" (Application No.: 201510715706.0), which is used to solve the The problem of interference; this patent application involves the method of performing LBT on unlicensed carriers according to the LBT level corresponding to the quality of service priority, but does not involve the LBT parameter selection method based on the interference level
