Embodiment Construction

[0020] Below in conjunction with the drawings, preferred embodiments of the present invention are given and described in detail.

[0021] Such as figure 1 As shown, the present invention, that is, a load-based device configuration method for listening first and speaking parameters, comprises the following steps:

[0022] Step S1, the base station configures the maximum number of LBE LBT executions N and / or the maximum LBE LBT execution time T for the terminal;

[0023] Among them, the maximum number of LBE LBT execution times N means that for each uplink resource allocation, the terminal can perform LBELBT 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 execute LBE LBT; if the LBT is successful, the terminal will transmit in the subsequent allocated uplink subframe; if the LBT fails, the terminal will back off for ...

Abstract

The invention relates to a listen-before-talk parameter configuration method for load-based equipment, and the method comprises the steps: enabling a base station to configure the LBE LBT maximum execution frequency N and/or the LBE LBT maximum execution duration T for a terminal; and each time when the base station executes uplink resource allocation, the frequency of executing the LBE LBT by theterminal does not exceed the maximum execution frequency N of the LBE LBT, and/or the total time length of executing the LBE LBT by the terminal does not exceed the maximum execution time length T ofthe LBE LBT. According to the invention, the LBE LBT parameters are reasonably configured for the terminal, the delay requirements of different services and the energy consumption requirements of different terminals are met, the method can adapt to a complex dynamic interference environment, and the transmission performance of the system is improved.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a load-based device configuration method for listening before speaking parameters. 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 for e...
