Abstract

The invention provides a communication method and device which are used for improving the accuracy of SL DRX configuration. In the application, a first communication device can receive first information from a second communication device and send an SL DRX configuration corresponding to an SL connection between the first communication device and the second communication device to the second communication device, and the second communication device receives SL transmission from the first communication device according to the SL DRX configuration. Therefore, the configuration of the SL DRX better meets the transmission requirement between the first communication equipment and the second communication equipment, and the energy-saving effect of the second communication equipment is enhanced. The first information is used for determining the SL DRX configuration.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a communication method and device. Background technique [0002] In the wireless communication system, in order to save the power consumption of the terminal under the premise of ensuring the effective transmission of data, a discontinuous reception (DRX) mechanism is introduced to control the terminal to monitor the physical downlink control channel (physical downlink control channel, PDCCH) mode. [0003] When DRX is configured, the terminal can periodically enter the sleep state (sleep mode) at certain times. In the sleep state, the terminal does not need to monitor the PDCCH, and when it needs to monitor, the terminal wakes up from the sleep state (wake up) , so that the terminal can achieve the purpose of power saving. When the terminal is not configured with DRX or the terminal is not performing DRX, the terminal will continue to monitor the P...
