Embodiment 1
[0169] Embodiment 1: Determine the starting position of the paging time window under the extended DRX.
[0170] Step 1: AMF or RAN side node configures one or more of the following parameters:
[0171] PTW_start_offset: The offset to determine the start position of the paging time window. This parameter can be the PF_offset in the aforementioned paging parameters, or it can be an offset specially configured for the starting position of the paging time window under extended DRX, so that the UE side can start as soon as possible after the starting position of the paging time window Can listen to paging;
[0172] This parameter can be applied to all paging time windows in each paging superframe PH; it can also be only applicable to a certain paging time window in a paging superframe PH. Each paging time window under the paging superframe PH is configured with an offset;
[0173] k: the number of starting positions of evenly distributed paging time windows in the next paging su...
Embodiment 2
[0193] Embodiment 2: Determine the duration or cut-off position of the paging time window under the extended DRX.
[0194] Multiple determination methods are provided in this embodiment.
[0195] Mode 1: Determine the paging times n within the paging time window directly configured by the AMF or the RAN side node, specifically including:
[0196] Step 1: The AMF or RAN side node configures the number of paging n=4 in the paging time window, that is, when the UE configures extended DRX, there are 4 PFs (paging frames) or 4 in a paging time window that need to be monitored by the UE The PO (paging opportunity).
[0197] Step 2: For the UE configured with extended DRX, the duration of the paging time window under each paging superframe is the time occupied by n PFs (paging frames) or n POs (paging occasions).
[0198] Wherein, n=4 in this embodiment; PF or PO can be determined according to the existing NR paging mechanism. For example, PF_offset=0, T=32, N=T; UE_ID=33, Ns=2, a...

Abstract
The invention discloses an information determination method and device, and a parameter configuration method and device, which are used for providing a paging time window determination scheme under the condition that a DRX period is expanded in an NR system. At any node, which can be a network side or a terminal side, the information determination method provided by the embodiment of the invention comprises the following steps: determining a paging time window configuration parameter set under the condition that a discontinuous reception (DRX) period is expanded; and determining paging time window information according to the configuration parameters.
Description
technical field [0001] The present application relates to the field of communication technologies, and in particular to methods and devices for information determination and parameter configuration. Background technique [0002] In order to save terminal power consumption, a relatively long discontinuous reception (DRX) cycle may also be introduced into the new radio (NR) system, similar to extended discontinuous reception (Extended DRX, eDRX). Beam sweeping (beamsweeping) is introduced into NR, which has its own paging mechanism, such as the starting position of the paging frame and the position occupied by the paging slot. [0003] However, there is currently no relevant solution on how to determine the paging time window when an extended discontinuous reception (DRX) cycle is introduced in the NR system. Contents of the invention [0004] The embodiment of the present application provides a method and device for information determination and parameter configuration, so...
