Abstract

The invention relates to a low-power consumption wake-up signal paging process. Systems, methods, apparatuses, and computer program products are provided for informing a core network/base station of LP-WUS support by a UE for paging procedures on different frequency bands. For example, a method may include transmitting, to a network entity, LP-WUS capability information including information regarding one or more frequencies or frequency bands in which the LP-WUS is supported by the device, and receiving, from the network entity, the LP-WUS over frequencies or frequency bands included among the one or more frequencies or frequency bands in the transmitted LP-WUS capability information.

Description

Low power wake-up signal paging procedure Technical Field Certain example embodiments may relate generally to mobile or wireless telecommunication systems, such as third generation partnership project (3 GPP) Long Term Evolution (LTE), fifth generation (5G) Radio Access Technology (RAT), new Radio (NR) access technology, sixth generation (6G) systems, and/or other communication systems. For example, certain example embodiments may relate to systems and/or methods for informing a core network/base station of LP-WUS support by a UE for paging procedures on different frequency bands. Background Examples of mobile or wireless telecommunications systems may include Radio Frequency (RF) 5G RAT, universal Mobile Telecommunications System (UMTS) terrestrial radio access network (UTRAN), LTE evolved UTRAN (E-UTRAN), LTE-Advanced (LTE-a), LTE-a Pro, NR access technology, and/or MulteFire alliance. The 5G wireless system refers to the Next Generation (NG) radio system and network architecture. The 5G system is typically built on 5G NR, but a 5G (or NG) network may also be built on E-UTRA radio. NR is expected to support service classes such as enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC), and large-scale machine-type communications (mMTC). NR is expected to implement extremely broadband, ultra-robust, low latency connections and large scale networking to support internet of things (IoT). The next generation radio access network (NG-RAN) represents a 5G Radio Access Network (RAN) that can provide radio access for NR, LTE and LTE-a. Notably, a node in 5G that provides radio access functionality to user equipment (e.g., similar to a node B in UTRAN or an evolved node B (eNB) in LTE) may be referred to as a next generation node B (gNB) when built on an NR radio and a next generation eNB (NG-eNB) when built on an E-UTRA radio.
