Method and apparatus for performing paging in a communication system

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

• determining configuration information associated with a paging early indication (PEI);
• transmitting the configuration information;
• determining downlink control information (DCI) associated with the configuration information;
• transmitting the DCI,
• wherein the DCI includes an indication field for the PEI,
• wherein each bit included in the indication field indicates one user equipment (UE) subgroup among N UE subgroups,
• wherein a plurality of UEs monitoring a same paging occasion (PO) is divided into the N UE subgroups,
• wherein a bit for a UE subgroup to which a UE belongs included in the indication field indicates whether a PO corresponding to the bit among M POs is associated with monitoring;
• and
• transmitting a paging message on the PO in case that the bit indicates the PO associated with monitoring,
• wherein the configuration information includes information associated with a value of M.

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

• a transceiver;
• and
• a controller coupled with the transceiver and configured to:
• receive configuration information associated with a paging early indication (PEI);
• receive, based on the configuration information, downlink control information (DCI) including an indication field for the PEI, wherein each bit included in the indication field indicates one UE subgroup among N UE subgroups and wherein a plurality of UEs monitoring a same paging occasion (PO) is divided into the N UE subgroups;
• and
• identify, based on the indication field, whether to monitor a PO among M POs, wherein the PO corresponds to a bit for a UE subgroup to which the UE belongs, wherein the indication field includes the bit, and wherein M is identified based on the configuration information.

• wherein a plurality of UEs monitoring a same paging occasion (PO) is divided into the N UE subgroups,
• wherein a bit for a UE subgroup to which a UE belongs included in the indication field indicates whether a PO corresponding to the bit among M POs is associated with monitoring;
• and
• transmit a paging message on the PO in case that the bit indicates the PO associated with monitoring,
• wherein the configuration information includes information associated with a value of M.
