Problems solved by technology

In related technologies, the base station selects an RB offset value from the corresponding minimum set and sends it to the UE, so that the UE can find the corresponding RMSI CORESET according to the RB offset value, but the network configuration flexibility in this way is poor

Abstract

The present invention relates to an information indicating method and device, a method and device of searching RMSI of CORESET, a base station, user equipment, and a computer readable storage medium.The information indicating method includes the steps: adding time-frequency indication information which is configured for CORESET of RMSI (remaining system information) in PBCH (Physical Broadcast Channel) of SSB (Synchronization Signal Block); if the time-frequency indication information indicates time division multiplexing of CORESET of RMSI and SSB, according to the current frequency band, SCSof SSB and SCS of CORESET of RMSI, inquiring the pre-stored corresponding relationship, and obtaining a minimum set of RB (Resource Block) deviation values of the extended resource block, corresponding to the current frequency band; selecting an RB deviation value from the obtained minimum set of the extended RB deviation values, and adding the deviation index corresponding to the selected RB deviation value into the time-frequency indication information; and transmitting the SSB carrying the time-frequency indication information to the UE in a beam scanning manner. The information indicatingmethod increases flexibility of configuration.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to an information indication method and device, a method and device for searching a common control resource set (CORESET) of remaining key system information (RMSI), a base station, user equipment, and a computer-readable storage medium. Background technique [0002] In the recent 3rd Generation Partnership Project (3GPP) discussions, it is necessary to propose how to indicate the common control resource set (CORESET) information of the remaining key system information (RMSI) in the physical broadcast channel (Physical Broadcast Channel, referred to as PBCH) An important problem to be solved, wherein, the CORESET information of the RMSI includes frequency domain information and time domain information. For frequency domain information, in addition to indicating frequency division multiplexing (FDM) and time division multiplexing (TDM), frequency offset informat...
