Method and apparatus for transmitting and receiving paging message in next generation mobile communication system

A method performed by a base station in a wireless communication system, the method comprising:

• identifying a paging frame including one or more paging occasions, based on an offset associated with the paging frame, a system frame number, and a discontinuous reception (DRX) cycle of a user equipment (UE);
• identifying an index for a paging occasion to transmit a paging message based on a number of the one or more paging occasions included in the paging frame;
• and
• transmitting, to the UE, the paging message in the paging occasion based on the index for the paging occasion,
• wherein the paging occasion includes multiple time slots for paging,
• wherein the multiple time slots for paging are associated with remaining minimum system information (RMSI), and
• wherein the paging frame is further identified based on:
• (SFN+Offset) mod T=(T div N)*(UE_ID mod N),
• where SFN is the system frame number, Offset is the offset associated with the paging frame, T is the DRX cycle of the UE, N is a number of total paging frames in the T, and UE_ID is a mobile subscriber identity mod 1024.

A user equipment (UE) in a wireless communication system, the UE comprising:

• a transceiver;
• and
• a controller configured to:
• identify a paging frame including one or more paging occasions, based on an offset associated with the paging frame, a system frame number, and a discontinuous reception (DRX) cycle of the UE,
• identify an index for a paging occasion to be monitored based on a number of the one or more paging occasions included in the paging frame, and
• monitor the paging occasion based on the index for the paging occasion, wherein the paging occasion includes multiple time slots for paging,
• wherein the multiple time slots for paging are associated with remaining minimum system information (RMSI), and
• wherein the paging frame is further identified based on:
• (SFN+Offset) mod T=(T div N)*(UE_ID mod N),
• where SFN is the system frame number, Offset is the offset associated with the paging frame, T is the DRX cycle of the UE, N is a number of total paging frames in the T, and UE_ID is a mobile subscriber identity mod 1024.

• transmit, to the UE, the paging message in the paging occasion based on the index for the paging occasion,
• wherein the paging occasion includes multiple time slots for paging,
• wherein the multiple time slots for paging are associated with remaining minimum system information (RMSI), and
