Problems solved by technology

[0004] Due to the NR-U (5G NR in Unlicensed Spectrum, 5G NR operating in unlicensed spectrum) system, all channel transmission must be performed before LBT (Listen Before Talk) detection, if the UE can receive the paging message only after receiving the SIB1 message, It may cause the transmission of paging messages to be blocked due to LBT failure or COT (Channel Occupied Time) failure, resulting in a large delay in receiving paging messages, and it is also not conducive to the effective allocation of SIB1 resources

Abstract

The embodiment of the invention provides an NR-U system paging message transmission method, a base station and a terminal. The method comprises the following steps: determining to send a paging message, and sending the paging message and a synchronization signal block (SSB) message bearing a master information block (MIB) message to a terminal in the same time slot, so that the terminal receives the paging message in a public search space configured in the MIB. According to the NR-U system paging message transmission method, the base station and the terminal provided by the embodiments of the present invention, the transmission of the MIB is performed in the SSB, so that the terminal directly receives the paging message in the public search space configured in the MIB, and the terminal does not need to receive the paging message after receiving the SIB1 message, thereby saving the resource configuration of the SIB1, reducing the receiving time delay of the paging message, and simultaneously improving the user experience. The probability that transmission of paging messages is blocked due to LBT failure or COT failure can be reduced.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a transmission method, a base station and a terminal of an NR-U system paging message. Background technique [0002] The paging of the 5G NR (New Radio) system has two main application scenarios: one is the paging initiated by the core network, and the other is the paging initiated by the gNB (5G base station). The purpose of the paging initiated by the gNB is to notify the UE of system information updates. This kind of paging of the NR system can store the indication of the system message update on the control channel that sends the paging, that is, the PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel), instead of the data channel PDSCH (Physical Downlink Shared Channel, physical Downlink shared channel), the main purpose is to improve the downlink spectrum efficiency. [0003] The method of sending the paging message is very s...
