Embodiment Construction

[0044] Some wireless communication systems (e.g., New Radio (NR) systems, millimeter wave (mmW) systems, etc.) may support (a or more) User Equipment (UE). A base station (eg, eNodeB (eNB), Next Generation NodeB, or Gigabit NodeB (any of which may be referred to as a gNB)) may serve a large number of UEs within a cell. In order to effectively use the wake-up signal, the base station may transmit the wake-up signal to a UE with which wireless communication is to be performed. Generally, a UE monitors a wake-up signal during a wake-up signal monitoring period, and when the wake-up signal is detected, performs wireless communication through a wireless medium during an active period. By convention, the on-duration (eg, active period) and the start position between the wake-up signal are fixed on the timeline.

[0045] However, such conventional techniques can be problematic when wireless networks operate on shared or unlicensed radio spectrum bands. Communication in the unlicen...

Abstract

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a signal to a base station indicating a UE capability configuration. The EE may receive, over an unlicensed radio frequency spectrum band, a wakeup signal during a monitoring period, the wakeup signal indicating that wireless communications are to be performed between the EE and the base station during an active time period. The EE may identify a guard time period upon receiving the wakeup signal, wherein the guard time period is based at least in part on the EE capability configuration. The EE may perform, after an expiration of the guard time period, the wireless communications with the base station during the active time period.

Description

[0001] cross reference [0002] This patent application claims U.S. Provisional Patent Application No. 62 / 808,224, entitled "Wakeup Signaling in an Unlicensed Radio Frequency Spectrum Band," filed February 20, 2019, by Nam et al. and U.S. Patent Application No. 16 / 781,878, filed February 4, 2020, by Nam et al., entitled "Wakeup Signaling in an Unlicensed Radio Frequency Spectrum Band," both of which Each of the priority applications has been assigned to the assignee herein. technical field [0003] The following relates generally to wireless communications, and more specifically to wake-up signaling in unlicensed radio spectrum bands. Background technique [0004] Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and others. These systems are capable of supporting communication with multiple users by sharing available system resources (eg, time, frequency, and power...
