Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a counter value and a correlation threshold parameter associated with a wake-up signal for tracking (WUT) to be received by a wake-up receiver (WUR) of the UE. The UE may count WUR failure occurrences based at least in part on the correlation threshold parameter. The UE may initiate a beam recovery process in accordance with a quantity of WUR failure occurrences being greater than or equal to the counter value. In some aspects, the UE may receive an indication of a set of transmission configuration indication (TCI) states to be monitored. The UE may monitor, for each TCI state of the set of TCI states, a wake-up signal for tracking (WUT) using a wake-up receiver (WUR) of the UE. Numerous other aspects are described.

Description

WAKE-UP SIGNAL FOR TRACKING PROCESSING CROSS-REFERENCE TO RELATED APPLICATION [0001] This Patent Application claims priority to Israel Patent Application No. 304079, filed on June 27, 2023, entitled “WAKE-UP SIGNAL FOR TRACKING PROCESSING,” and assigned to the assignee hereof. The disclosure of the prior Application is considered part of and is incorporated by reference into this Patent Application. FIELD OF THE DISCLOSURE [0002] Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for wake-up signal fortracking processing. BACKGROUND [0003] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, or the like). Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single -carrier frequency division multiple access (SC- FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE/LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP). [0004] A wireless network may include one or more network nodes that support communication for wireless communication devices, such as a user equipment (UE) or multiple UEs. A UE may communicate with a network node via downlink communications and uplink communications. “Downlink” (or “DL”) refers to a communication link from the network node to the UE, and “uplink” (or “UL”) refers to a communication link from the UE to the network node. Some wireless networks may support device-to-device communication, such as via a local link (e.g., a sidelink (SL), a wireless local area network (WLAN) link, and/or a wireless personal area network (WPAN) link, among other examples). [0005] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate on a municipal, national, regional, and/or global level. New Radio (NR), which may be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the 3GPP. NR is designed to better support mobile broadband internet access by improving 1 SUBSTITUTE SHEET (RULE 26) spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink, using CP-OFDM and/or single-carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink, as well as supporting beamforming, multiple-input multiple -output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain useful. SUMMARY [0006] Some aspects described herein relate to a method of wireless communication performed by a user equipment (UE). The method may include receiving an indication of a counter value and a correlation threshold parameter associated with a wake-up signal for tracking (WUT) to be received by a wake-up receiver (WUR) of the UE. The method may include counting WUR failure occurrences based at least in part on the correlation threshold parameter. The method may include initiating a beam recovery process in accordance with a quantity of WUR failure occurrences being greater than or equal to the counter value. [0007] Some aspects described herein relate to a method of wireless communication performed by a UE. The method may include receiving an indication of a set of transmission configuration indication (TCI) states, of a plurality of TCI states, to be monitored by the UE. The method may include monitoring, for each TCI state of the set of TCI states, a WUT using a WUR of the UE. [0008] Some aspects described herein relate to a method of wireless communication performed by a network node. The method may include transmitting an indication of a counter value and a correlation threshold parameter associated with a WUT to be received by a WUR of a UE. The method may include receiving an indication of a beam recovery process in accordance with a quantity of WUR failure occurrences being greater than or equal to the counter value.
