Description

Method and device for transmitting and receiving discovery signals, base station and user equipment Technical field

The present disclosure relates to the field of communication technologies, and in particular, to a method and device for transmitting a discovery signal (DRS), a method and device for receiving a DRS, a base station, user equipment, and a computer-readable storage medium.

Background technique

With the rapid development of wireless communication technology, the fifth generation of mobile communication technology (5th Generation, referred to as 5G) has appeared. The 3rd Generation Partnership Project (3GPP) has recently conducted research on the 5G New Radio Unlicensed Spectrum (NR-U). Most of the opinions suggest that NR-U can support independent groups. And considers that the design in 5G New Radio (NR) is to be inherited to 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, such as Listen Before Talk (LBT).

At present, 3GPP, R16, 5G, and NR-U have discussed solutions to support independent networking of unlicensed cells. Both the downlink signal and the initial access need to consider design changes caused by LBT. In the NR-U independent networking (SA), the initial access and synchronization and channel discovery cannot depend on the operator's network and need independent support.

The downlink signals such as the synchronization signal and related system information can be defined as part of the discovery signal (DRS), and the sending period of the synchronization signal (part of the discovery signal) in the initial access can start from 40ms. The NR synchronization signal transmission period is {5, 10, 20, 40, 80, 160} ms. Unlicensed spectrum may not require a period as flexible as NR, but NR-U needs to be networked independently, taking into account UE access delay and measurement, paging, etc., and directly citing the licensed spectrum-assisted access (LAA) cycle Also need to consider, need to consider more DRS transmission timing.

In the transmission of the synchronization signal, a scheme for increasing the transmission opportunity is considered, that is, transmission shifting caused by LBT is increased in one half frame (if one half frame is sufficient) of one DRS cycle. However, there may be no opportunity to send a synchronization signal in a DRS half frame, and after waiting for this opportunity, it is necessary to wait 40ms, and the waiting time is long.

In order to solve the problem of long waiting time, a 40ms minimum period scheme in LAA can be adopted, or a 20ms minimum period scheme can be defined. However, the 40ms minimum period scheme may not meet the access requirements. The 20ms minimum period scheme has a high frequency of UE monitoring, which is not conducive to power saving. Energy saving goals.
