Method and apparatus for configuring information, base station and user equipment

A method of acquiring a common control resource set (CORESET) of remaining minimum system information (RMSI), applicable to user equipment (UE), the method comprising:

• receiving first configuration information and second configuration information sent by a base station, wherein
• the first configuration information is configured in a radio resource control (RRC) signaling and indicates, for a bandwidth part (BWP), a relative position from a frequency-domain starting position of a synchronization broadcast block (SSB) corresponding to the BWP to a frequency-domain starting position of the BWP, and
• the second configuration information is generated for index information in a physical broadcast channel (PBCH) of the SSB corresponding to the BWP, wherein the second configuration information comprises a timing pattern, half-frame indication information, and configuration information on RMSI physical downlink control channel (PDCCH) for the SSB, and the half-frame indication information indicates an identifier of a half-frame of a current radio frame carrying the SSB;
• acquiring a synchronization signal of an SSB corresponding to a new active BWP based on the first configuration information, the second configuration information, an acquired identifier of the new active BWP and the frequency-domain starting position of the new active BWP carried in the RRC signaling;
• skipping a reading to the PBCH of the SSB corresponding to the new active BWP;
• obtaining a time-frequency position of the SSB corresponding to the new active BWP based on the configuration information on the RMSI PDCCH corresponding to the new active BWP carried in the RRC signaling and the synchronization signal of the SSB corresponding to the new active BWP;
• calculating a position of the CORESET of RMSI for the new active BWP from the time-frequency position of the SSB corresponding to the new active BWP;
• and
• acquiring the CORESET of RMSI for the new active BWP based on the position of the CORESET of RMSI.
