Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of U.S. Patent Application No. 17/308,860, entitled, "VEHICLE-TO-EVERYTHING (V2X) MESSAGE MONITORING," filed on May 5, 2021, and the benefit of U.S. Provisional Patent Application No. 63/020,867, entitled, "VEHICLE-TO-EVERYTHING (V2X) MESSAGE MONITORING," filed on May 6, 2020, which is expressly incorporated by reference herein in its entirety. TECHNICAL FIELD Aspects of the present disclosure relate generally to wireless communication systems, and more particularly, to vehicle-to-everything (V2X) message monitoring. INTRODUCTION Wireless communication networks are widely deployed to provide various communication services such as voice, video, packet data, messaging, broadcast, and the like. These wireless networks may be multiple-access networks capable of supporting multiple users by sharing the available network resources. Such networks, which are usually multiple access networks, support communications for multiple users by sharing the available network resources. A wireless communication network may include a number of base stations or node Bs that can support communication for a number of user equipments (UEs). A UE may communicate with a base station via downlink and uplink. The downlink (or forward link) refers to the communication link from the base station to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the base station. A base station may transmit data and control information on the downlink to a UE and/or may receive data and control information on the uplink from the UE. On the downlink, a transmission from the base station may encounter interference due to transmissions from neighbor base stations or from other wireless radio frequency (RF) transmitters. On the uplink, a transmission from the UE may encounter interference from uplink transmissions of other UEs communicating with the neighbor base stations or from other wireless RF transmitters. This interference may degrade performance on both the downlink and uplink. As the demand for mobile broadband access continues to increase, the possibilities of interference and congested networks grows with more UEs accessing the long-range wireless communication networks and more short-range wireless systems being deployed in communities. Research and development continue to advance wireless technologies not only to meet the growing demand for mobile broadband access, but to advance and enhance the user experience with mobile communications. Vehicle-to-everything (V2X) technology enables sharing of information from a vehicle to another device or entity that may affect the vehicle, and vice versa. V2X technology is associated with a vehicular communication system that can include one or more aspects or types of communication, such as vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-network (V2N), vehicle-to-pedestrian (V2P), vehicle-to-device (V2D), and vehicle-to-grid (V2G), as illustrative, non-limiting examples. V2X technology can utilize cellular based communication or wireless local area network communication. In some implementations, messages and communication for the V2X technology are at an application and use an underlying radio as pipe (a communication path). V2X-capable vehicles periodically broadcast their current status using application-layer messages such as the Basic Safety Message (BSM) or Cooperative Awareness Messages (CAM), nominally transmitted at a 100 milliseconds (ms) periodicity. These transmissions constitute the V2X basic safety capability, and at a minimum include vehicle identity, location, and motion state. In addition to basic safety, standards bodies, such as Society of Automotive Engineers (SAE), European Telecommunications Standards Institute (ETSI)-European Telecommunication Standard (ETS), and Chinese Standards Association, Society of Automotive Engineers of China (CSAE), are developing application-layer standards for advanced features including sensor-sharing (such as dissemination of detected vehicles or objects) and coordinated driving (such as sharing and negotiating intended maneuvers). Such messages may be detected may on or more UEs and used to alert a vulnerable road users (VRU), such as pedestrians, cyclists, and other micro-mobility user (e.g., scooter, Segway, etc.), to the presence of one or more vehicles. As compared to a roadway vehicle, such as a car, truck, or other vehicle that includes an alternator, a UE typically includes a storage device, such as a battery, which can be sensitive to power consumption. Frequent or continuous monitoring of V2X application-layer messages can present an unacceptable power drain (battery drain) for the UE. SUMMARY The following summarizes some aspects of the present disclosure to provide a basic understanding of the discussed technology. This summary is not an extensive overview of all contemplated features of the disclosure and
