The UE may use Discontinuous Reception (DRX) in RRC_IDLE and
RRC_INACTIVE state in order to reduce power consumption.
The UE monitors one Paging Occasion (PO) per DRX cycle.
A PO is a set of PDCCH monitoring occasions and can consist
of multiple time slots (e.g. subframe or OFDM symbol) where paging DCI can be
sent.
Different UEs based on their UE_ID are divided into the
multiple paging groups per every DRX cycle duration and each paging group is
linked to a specific Paging Frame(PF). Every Paging Frame (PF) may contain
multiple Paging Occasions (POs).
UE first should calculate its Paging Frame(PF) and then
identifies its PO within the PF.
Here is an example that 16 UEs with their IDs are going to be
paged through 5G NR Air Interface (5G NR Uu) using RRC protocol. I also use all
the necessary formulas from 3GPP specs that are vital to calculate the Paging
Frames, Paging Occasions and the paging groups.
