Abstract

The present disclosure relates to a method and apparatus for transmitting a DRS, a method and apparatus for receiving a DRS, a base station, user equipment, and a computer readable storage medium. Themethod for transmitting the DRS includes: transmitting the DRS in the first transmission sub-period, where the transmission period of the DRS includes the first transmission sub-period and the secondtransmission sub-period; if the DRS is not successfully sent in the first transmission sub-period, the DRS is sent in the second transmission sub-period; according to the method for transmitting theDRS, when the DRS is sent in the first transmission sub-period and the DRS is not successfully sent in the first transmission sub-period, the DRS is sent in the second transmission sub-period to increase the transmission opportunity of the DRS, which can meet the requirements of the network and bring more access opportunities to the UE.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a discovery signal (DRS) sending method and device, a DRS receiving method and device, a base station, user equipment, and a computer-readable storage medium. Background technique [0002] With the rapid development of wireless communication technology, the fifth generation of mobile communication technology (5th Generation, 5G for short) has emerged. The 3rd Generation Partnership Project (3GPP) has recently conducted research on the 5G New Radio Unlicensed Spectrum (NR-U), and most of them believe that NR-U can support independent groups. network, and believes that the design in 5G New Radio (NR) should be inherited into NR-U as much as possible. In the design of unlicensed spectrum, the first thing to consider is that there are relevant regulations in various regions of the world, for example, Listen before Talk (LBT for short). [0003] At present, 3G...
