Schemes for SSB to paging coreset mapping in NR

A base station for transmitting and/or receiving data to/from a user equipment (UE) in a communication system, comprising:

• circuitry which, in operation,
• determines a paging region in which user equipments (UEs) are paged,
• determines an offset with respect to a starting location of the paging region, the offset indicating a location of paging information for paging the UE relative to the starting location of the paging region, and the offset indicating a frequency position in a paging location indication indicative of locations of the paging information within the paging region,
• determines an ordinal value of a location of a synchronization signal block (SSB) in a synchronization bitmap, and
• allocates the paging information for paging the UE to a resource on the location indicated by the offset, and
• a transmitter which, in operation, transmits the paging information on the resource indicated by the offset to the UE.

A data transmission and/or reception method to be performed by a user equipment (UE) transmitting and/or receiving data to/from a base station in a communication system, the method comprising:

• calculating a starting location of a paging region comprising resources in which user equipments (UEs) are paged, the paging region including paging information for paging the UE;
• receiving, from the base station, an indication of an offset with respect to the starting location of the paging region;
• determining, based on the indication, the offset with respect to the starting location of the paging region to obtain a location of the paging information for paging the UE, the offset indicating the location of the paging information for paging the UE relative to the starting location of the paging region, and the offset indicating a frequency position for a corresponding in a paging location indication indicative of locations of the paging information within the paging region;
• and
• determining an ordinal value of a location of a synchronization signal block (SSB) in a synchronization bitmap.
