Embodiment Construction

[0021] Below in conjunction with the drawings, preferred embodiments of the present invention are given and described in detail.

[0022] like figure 1 As shown, the present invention, that is, a method for configuring parameters of a frame-based device that listens first and then talks, comprises the following steps:

[0023] Step S1, the base station configures the FBE LBT execution times N for the terminal, or configures the FBE LBT execution times N and the FBE LBT time slot length for the terminal;

[0024] Among them, the number of FBE LBT execution times N means that for each uplink resource allocation, the terminal can perform FBE LBT at most N times; assuming that the base station allocates one or more consecutive subframes for the terminal to perform uplink transmission, the terminal starts from the first uplink subframe The frame starts to perform FBE LBT; if the LBT is successful, the channel is detected to be idle, the terminal will transmit in the subsequent all...

Abstract

The present invention relates to a method for configuring parameters of a listen-before-talk frame-based device, wherein the base station configures the number of FBE LBT executions N for the terminal, or configures the number of FBE LBT executions N and the length of the FBE LBT time slot for the terminal; When performing uplink resource allocation for the first time, the number of times the terminal executes FBE LBT does not exceed the number of times N of FBE LBT executions; the terminal configures FBE LBT time slots based on the length of the FBE LBT time slot, and performs Perform FBE LBT channel detection in . The invention satisfies the time delay requirements of different services and the energy consumption requirements of different terminals by rationally configuring FBE LBT parameters for the terminals, and can adapt to complex and dynamic interference environments, thereby improving the transmission performance of the system.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a parameter configuration method of a frame-based device for listening before talking. 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...
