Abstract

The invention provides a signal sending method and device and a storage medium. The method comprises the following steps: receiving a first signal in a first time domain unit, determining a CW value according to the state information of the first signal, and sending a target signal according to the CW value, wherein the first time domain unit is a preset time domain unit or a time period related to the last burst transmission bus, and the state information of the first signal comprises demodulation information of the first signal. Therefore, based on the first signal received in the first timedomain unit, the CW value is determined according to the state information of the first signal, and the CW value can be more comprehensively, accurately and dynamically adjusted.

Description

technical field [0001] The present application relates to digital communication transmission technology, in particular to a signal sending method, device and storage medium. Background technique [0002] In the fifth-generation mobile communication technology (5th-Generation mobile communication technology, 5G) system, information transmission with licensed spectrum and information transmission with unlicensed spectrum are included. Among them, for the signal transmission of the unlicensed spectrum, before each signal transmission process, especially for the random access process, data transmission process or signaling transmission process, it is almost necessary to "Listen Before Talk (LBT) "The operation of this mechanism. If the LBT operation mode of type (Category) 4 is adopted, the contention window (ContentionWindow, CW) needs to be adjusted during the uplink transmission. However, the existing CW adjustment method only adjusts the CW value based on the time slot of ...
