Abstract

A method and apparatus (900) for wake-up signal (WUS) detection. The method may include receiving user equipment (UE) grouping information and WUS alternate information (402); determining an initial WUS sequence based on the UE grouping information (404); and monitoring a WUS sequence based on the initial WUS sequence and the WUS alternating information (406).

Description

technical field [0001] Embodiments of the present application relate generally to wireless communication technologies, and more particularly to methods and apparatus for wake-up signal (WUS) detection in Narrowband Internet of Things (NB-IoT) technology. Background technique [0002] In NB-IoT technology, for power saving in Long Term Evolution (LTE) Release (R) 15, a WUS mechanism is introduced, wherein WUS indicates whether there is a paging procedure in a predefined paging occasion (PO). [0003] Specifically, when the WUS mechanism is disabled, the UE always monitors the paging messages on the PO. When the WUS mechanism is enabled, the UE monitors in the PO for possible subsequent paging messages in response to the UE detecting WUS, so that blind detection of the Physical Downlink Control Channel (PDCCH) can be performed. On the other hand, when the WUS mechanism is enabled, the UE will not monitor subsequent paging messages in the PO in response to the UE not detecting...
