1. An apparatus of a radio access network (RAN), comprising:
one or more processors; and
a memory storing instructions that, when executed by the one or more processors, cause the one or more processors to operate the apparatus to:
collect packet arrival history data for a user equipment (UE) corresponding to a buffer of the RAN;
predict, based on the packet arrival history data, whether a packet for the UE will arrive at the buffer during a prediction window spanning from a downlink control information (DCI) with a cyclic redundancy check (CRC) scrambled by a power-saving radio network temporary identifier (PS-RNTI) (DCP) occasion and an end of a connected mode discontinuous reception (CDRX) on duration window corresponding to the DCP occasion; and
send, to the UE, a DCP during the DCP occasion, the DCP indicating whether the UE is to perform PDCCH monitoring during the CDRX on duration window based on the predicting whether the packet for the UE will arrive at the buffer during the prediction window.
