Hi,
I want to know what parameters（<NW-provided_eDRX_value） mean.
The following figure shows parameters
A:Requested_eDRX_value
B:<NW-provided_eDRX_value
C:Paging_time_window
I can understand the parameters: A and B through the figure below
How should I understand parameter C? Can you illustrate it in a diagram
Thank you for all your assistance.
Kind regards,
Peter.Min
Hi Peter,
I am no expert but will add some things i find useful when understanding DRX.
Link to paper: Energy_efficient_tuning_of_the_NB_IoT_stack_Camera_ready_paper.pdf (uio.no)
Here is where to configure https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.6.0/nrf/include/modem/lte_lc.html#c.lte_lc_ptw_set
From this paper form Rohde & Schwarz: https://www.mobilewirelesstesting.com/wp-content/uploads/2019/07/Power-saving-methods-for-LTE-M-and-NB-IoT-devices_wp_en_3609-3820-52_v0100.pdf
"PTW is the time period configured for a UE in the I-eDRX cycle during which the UE monitors paging occasions (PO) on the PDCCH. In the remaining cycle time, the UE does not monitor the PDCCH. Thus, the network considers the UE unreachable for paging until the next paging hyperfame (PH) comes along"
From the GSMA paper under eDRX there is this description.
Link: CLP.29-v2.0.pdf (gsma.com)
"Every eDRX cycle can be configured with a paging transmission window (PTW) containing a number of paging opportunities. The eDRX cycle determines the fundamental downlink reachability and the PTW determines with what reliability the reachability can be guaranteed under, such as, varying load conditions."
And there is a section on it in the ETSI TS 136 304: https://www.etsi.org/deliver/etsi_ts/136300_136399/136304/15.05.00_60/ts_136304v150500p.pdf
"The period configured for a UE in extended DRX, during which the UE monitors Paging Occasions following DRX cycle"

Hi,
The NW-provided_eDRX_value provides info that can be found in the 3GPP TS 24.008, subclause 10.5.5.32. The eDRX value refers to bit 4 to 1 of octet 3 of the Extended DRX parameters information element.

Hope this helps.
