Embodiment 1

[0091] Embodiment 1 of the present application provides a method for confirming an idle state reference signal. The method is executed by a UE. The technical scenario of the embodiment of the present application is that the paging indication (Paging Indication, PI) is at the paging occasion (Paging Occasion, PO). Previously, PI was used to indicate whether the UE needs to monitor PO. PI is also called Paging Early Indication (PEI) or WakeUp Signal (WUS). The embodiment of this application assumes that the UE needs to process a total of 3 SS bursts (for AGC, time-frequency synchronization, etc.) before PO, and the embodiment of this application assumes that the UE needs to process 1 SS burst plus 1 reference signal before PO. methods such as image 3 As shown, it can specifically include:

[0092] Step S301, the UE determines that one reference signal after one SS burst or SS block closest to the PO is valid.

[0093] Specifically, the above-mentioned valid reference signals...

Embodiment 2

[0099] The second embodiment of the present application provides a method for confirming an idle state reference signal. The method is executed by the UE. The technical scenario of the embodiment of the present application is that the paging indication is before the paging occasion, and the PI is used to indicate whether the UE needs to monitor the PO. . PI is also known as paging advance indication or wake-up signal. In this embodiment of the present application, it is assumed that the UE needs to process a total of 2 reference signals (such as TRS) before PO. In this embodiment of the present application, there are reference signals for assistance, and 2 reference signals can replace 2 SS bursts, so it is equivalent to need to process 2 SS burst, the method is as follows Figure 4 As shown, it can specifically include:

[0100] Step S401, the UE determines that the two reference signals after the one SS burst closest to the PO are valid.

Embodiment 3

[0107] The third embodiment of the present application provides a method for confirming an idle state reference signal. The method is executed by the UE. The technical scenario of the embodiment of the present application is that the paging indication is before the paging occasion, and the PI is used to indicate whether the UE needs to monitor the PO. . PI is also known as paging advance indication or wake-up signal. In this embodiment of the present application, it is assumed that the UE needs to process a total of 3 reference signals (such as TRS) before PO. In this embodiment of the present application, there are reference signals for assistance, and 3 reference signals can replace 3 SS bursts, so it is equivalent to need to process Three SS bursts are different from the second embodiment in that the UE determines that the three reference signals after one SS burst closest to the PO are valid.

Abstract

The embodiment of the invention provides an idle state reference signal confirmation method and related products, the method is applied to UE, and the method comprises the following steps: the UE confirms that a reference signal before paging opportunity (PO) is valid. According to the technical scheme provided by the invention, the common optimization of UE energy conservation and system overhead is achieved.

Description

technical field [0001] The present application relates to the technical field of communication processing, and in particular, to a method for confirming an idle state reference signal and related products. Background technique [0002] When the UE is in an idle state (Idle mode, RRC IDLE), the UE needs to monitor the paging PDCCH (paging Physical Downlink Control Channel). Generally speaking, the UE needs to determine the paging PDCCH monitoring occasion (paging PDCCH monitoring occasion) through PF (Paging Frame, paging frame), PO (Paging Occasion, paging occasion) and paging search space set configuration. In 5G NR, the UE relies on the synchronization signal block to perform AGC (automatic gain control, automatic gain control) adjustment / time-frequency tracking (channel tracking) / measurement. Since synchronization signal block bursts do not exist in every subframe or every time slot, synchronization signal block bursts are sent at a certain time period, such as 5 ms, 10 ...
