1. A method for reducing paging in a wireless communication, comprising:
transmitting, by a network entity, a network message to a plurality of user equipment (UE), wherein the network message carries a network parameter and configuration information of a paging message scheduled to be transmitted at a predetermined time, wherein the configuration information includes a paging cycle, a paging frame (PF), a paging occasion (PO), a paging offset, a number of paging sub-groups in the cell (Nps), an indicating signal offset (ISO) and paging sub-groups information; and
transmitting, by the network entity, an indicating signal at the indicating signal offset (ISO) prior to the scheduled transmission of the paging message, wherein the indicating signal indicates if at least one of the plurality of UE will be paged in next paging occasion,
wherein transmitting the indicating signal comprises:
dividing a group of the plurality of user equipment associated with a common paging occasion (PO) into a plurality of paging sub-groups of the user equipment;
assigning each paging sub-group of the plurality of paging sub-groups, a unique paging sub-group identity; and
associating the paging sub-group identity to the indicating signal to indicate one of presence or absence of a paging Downlink Control Information (DCI) for each paging sub-group of the plurality of paging sub-groups,
wherein the paging sub-group identity is determined based on a pre-specified formula including the Nps, wherein the pre-specified formula is:
a paging_sub_group Identity=floor(User Equipment(UE)Identity(UE_ID)/(N*Ns)) mod Nps,
wherein N is number of paging frames and Ns is number of paging occasion per paging frame.
