Abrégé

This disclosure relates to a method and an apparatus for indicating a position of a cell-defining synchronization signal block (SSB) and searching for the same, a base station, user equipment and a computer-readable storage medium. A method of indicating a position of a cell-defining SSB includes: acquiring on-off indication information set in a physical broadcast channel (PBCH) of a non-cell-defining SSB, where the on-off indication information is a first value or a second value; setting, in response to that the on-off indication information is the first value, SSB position indication information in the PBCH to indicate a position of a raster or a raster group in which a cell-defining SSB is located; setting, in response to that the on-off indication information is the second value, gap indication information in the PBCH to indicate that there is no cell-defining SSB within a range of a current frequency band, wherein the range has a length of a gap value and is centered at a position of the current SSB; and sending the SSB to user equipment (UE). The examples of the present disclosure enable the UE to reduce the searching time.
