Hi Experts,
In DRX feature, the on duration timer is 2 pdcch subframe.
Does that means 2 ms?
What will happen if the UE in sleep cycle and paging happens?

2

Yes.

Idle mode DRX is controlled via paging.
UE knows on which PF & PO it has to wake up by reading if paging related settings.
So if UE in sleep state and enb sends paging to UE then that’s mis-configuration of paging parameters.
eNB & UE having alignment wrt paging to avoid such issues

Thanks dear!
Maybe UE in sleeping mode and receives MT from another UE, it cannot be configurable.

4

MT from another UE is still a paging message.

5

Yes, and what will happen if UE in sleeping cycle and received MT?

6

UE wakes up on paging cycle it is supposed to listen to.
eNB also knows which POs UE will wake up for.
So pages UE on those occasions.

This feature is C-DRX, discontinous receive in connected mode.
UE listen to paging in idle mode.

UE cannot listen to Paging signal while on DRX Sleep Cycle. Here is an explainer video: Energy Saving Techniques for UE in 5G: RRC States, DRX, and CDRX - YouTube
