Patent ID: 11388652

Abstract:
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. In response to that the on-off indication information is the first value, the base station sets 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. In response to that the on-off indication information is the second value, the base station sets gap indication information in the PBCH to indicate that there is no cell-defining SSB within a range of a current frequency band. 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).
