Method and apparatus for indicating transmitting power difference, and method and apparatus for compensating power

A method of compensating a power, the method comprising:

• receiving, by a user equipment (UE), a synchronization signal block (SSB) transmitted by a base station;
• parsing, by the UE, a preset number of successive SSBs which are successively received so as to obtain primary synchronization signal (PSS) transmitting powers of the preset number of successive SSBs, wherein the successive SSBs are transmitted successively based on a beam scanning manner;
• deciding, by the UE, whether the PSS transmitting powers of the preset number of successive SSBs conform to a preset fixed pattern;
• in response to determining that the PSS transmitting powers of the preset number of successive SSBs conform to the preset fixed pattern, determining, by the UE, that a transmitting power difference between the SSB and a physical downlink control channel (PDCCH) of remaining minimum system information (RMSI) corresponding to the SSB is greater than a preset threshold;
• and
• compensating, by the UE, a transmitting power of the PDCCH in response to receiving the PDCCH.

A base station, comprising:

• a processor;
• and
• a memory for storing processor executable instructions;
• wherein the processor is configured to:
• in response to determining that a transmitting power difference between a synchronization signal block (SSB) and a physical downlink control channel (PDCCH) of remaining minimum system information (RMSI) corresponding to the SSB is greater than a preset threshold, set primary synchronization signal (PSS) transmitting powers of a preset number of successive SSBs in a preset fixed pattern, wherein the preset fixed pattern indicates that the transmitting power difference is greater than the preset threshold, wherein the successive SSBs are transmitted successively based on a beam scanning manner;
• and
• transmit the SSB to a user equipment (UE) in the beam scanning manner.
