1. A method, performed by a network node in a radio access network (RAN), for selective paging of a plurality of user equipment (UEs) operating in a cell served by the network node, the method comprising:
assigning the plurality of UEs to a plurality of paging subgroups based on one or more operating parameters of the respective UEs, wherein the paging subgroups are associated with a first sequence of paging occasions (POs) to which all of the UEs are assigned;
transmitting a paging indicator in downlink control information (DCI) on a physical downlink control channel (PDCCH), wherein the paging indicator indicates which of the plurality of paging subgroups associated with a PO of the first sequence should receive a paging message from the network node; and
transmitting the paging message within the cell on a physical downlink shared channel PDSCH).
