摘要

对于可穿戴设备和物联网终端来说，设备的功耗至关重要。低功耗唤醒接收机和唤醒信号技术能够实现微瓦级的终端待机功耗，大幅度提升终端设备的电池寿命，可广泛适用于智能可穿戴设备、物联网设备、智能手机等终端类型。该技术已经被3GPP标准组织立项研究，有望成为5G-Advanced中终端侧的标志性技术之一。对低功耗唤醒接收机和唤醒信号技术进行了初步探讨，包括低功耗唤醒接收机的应用场景和需求、电路结构、唤醒信号设计、移动性和测量、与现有系统共存、干扰抑制等方面。

Abstract

Power consumption is critical for wearable and IoT (Internet of things) devices.Device standby with micro-watt level power consumption can be enabled by using low-power wake-up receiver/wake-up signal technology

which can increase the device battery life and are widely applicable to smart wearables

Internet of things

smart phones

etc.Study item on low power wake-up receiver and wake-up signal technology has been approved in 3GPP

and was considered as one of the iconic technologies for mobile devices in 5G-Advanced.Preliminary discussion on low power wake-up receiver and wake-up signal technology were provided

including use case and requirements

low power wake-up receiver structure

wake-up signal design

mobility and measurement aspects

co-existence with legacy system

anti-interference design.
