Frequency domain information indicating method and apparatus for common control resource set of remaining system information

Abstract

The present invention relates to a frequency domain information indicating method and apparatus for CORESET (common control resource set) of RMSI (remaining system information), a method and apparatusfor searching CORESET of RMSI, a base station, user equipment, and a computer readable storage medium. The frequency domain information indicating method of CORESET of RMSI includes the steps: addingindication information to a physical broadcast channel PBCH of a synchronous broadcast block SSB, wherein the indication information includes first indication information and the first indication information is used to indicate time division multiplexing or frequency division multiplexing of the CORESET of the RMSI, carrying the indication information, to the user equipment UE in a beam scanningmanner. The frequency domain information indicating method of CORESET of RMSI can use as few bits as possible to indicate the frequency domain information of the CORESET of the RMSI.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a method and device for indicating frequency domain information of a common control resource set (CORESET) of remaining critical system information (RMSI), a method and device for searching CORESET of RMSI, a base station, user equipment and a computer readable storage media. Background technique [0002] In the recent 3rd Generation Partnership Project (3GPP) discussions, it was proposed how to indicate the time-frequency location of the Common Control Resource Set (CORESET) of the Remaining Critical System Information (RMSI) in the Physical Broadcast Channel (PBCH) is one of the issues to be solved important question. Since the current PBCH only reserves the length of about 8 bits for the CORESET indication information of RMSI, and one or two bits may need to be reserved for future use, this raises the question of how to indicate the CORESET position of R...

AI Technical Summary

Problems solved by technology

Since the current PBCH only reserves the length of about 8 bits for the CORESET indication information of RMSI, and one or two bits may need to be reserved for future use, this raises the question of how to indicate the CORESET position of RMSI in the broadband system In addition, there are still conclusions that multiple simultaneous broadcast blocks (SSB) can correspond to one RMSI, which increases the difficulty of indicating the position in the frequency domain

In addition, because the time domain combination of the PBCH channel must be considered, the PBCH content of the SSB corresponding to each beam is required to be consistent, which limits the degree of freedom of the frequency domain indication of CORESET of RMSI and increases the difficulty of indication
