Abstract: In an aspect, an apparatus, e.g., a base station of a first network, maybe configured to receive UE capability information from each UE of a plurality of UEs, the UE capability information indicating a number of different carrier synchronization timings that the UE can track within a plurality of carriers. The carriers maybe associated with multiple different networks including the first network. The apparatus maybe configured to determine, based on the received UE capability information, a set of synchronization-timing priorities indicating a priority for timing synchronization types for use within each carrier of a set of carriers of the plurality of carriers, and broadcast the set to the UEs. In an aspect, a UE may determine and send the UE capability to a base station. The UE may receive the set of synchronization-timing priorities and perform timing synchronization based on the received set of synchronization-timing priorities.

Abstract: Various aspects of the disclosure relate to a request-response mechanism for sharing sensor information. For example, sensor devices (e.g., in vehicles, fixed structures, or a combination thereof) may selectively share information acquired by the sensor devices. The disclosure relates in some aspects to avoiding redundant transmissions of sensor information. For example, a sensor device of a set of sensor devices may determine which sensor device should transmit information and/or the time(s) at which that sensor device should transmit the information.

Abstract: Methods, systems, and devices are describe for signaling protocols for device-to-device discovery operations in a wireless communication system. A user equipment (UE) may be communicating with a serving base station using a first frequency in a first frequency band. The UE may transmit, to the serving base station, information associated with performing a discovery scan procedure on a second frequency in a second frequency band during a discovery scan interval. The first frequency may be different from the second frequency. The UE may identify a capability to skip one or more downlink transmissions from the serving base station during the discovery scan interval.

Abstract: Methods, systems, and devices are described for signaling protocols for proximity service functions in a wireless communication system. A first wireless device may identify a wireless relay requirement associated with the first wireless device. A proximity service protocol may be initiated between the first wireless device and a second wireless device based at least in part on the identified wireless relay requirement. The proximity service protocol may be initiated prior to an initiation of a communication data exchange between the first wireless device and the second wireless device. A relay link may be established, via the ProSe protocol, between the first wireless device and the second wireless device based at least in part on the identified wireless relay requirement.

Abstract: Wireless communications systems and methods related to sharing of sensor data among vehicles are provided. A first vehicle receives, from a second vehicle, first sensing information associated with a first object. The first vehicle detects sensor data associated with a second object. The first vehicle transmits second sensing information associated with the second object based on at least the sensor data, the first sensing information, and a transmission latency budget for the second sensing information. The first sensing information includes geographical location information of the first object. The second sensing information includes geographical location information of the second object. Other aspects, embodiments, and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter user equipment may determine a beam to be used to transmit a vehicle-to-everything (V2X) communication to a receiver UE; may determine one or more eligible resource blocks of the beam that are candidates for the V2X communication based at least in part on a schedule associated with the beam; may transmit, to the receiver UE, a proposed schedule that indicates the one or more eligible resource blocks of the beam that are candidates for the V2X communication; and may transmit the V2X communication to the receiver UE via the beam based at least in part on transmitting the proposed schedule. Numerous other aspects are provided.

Abstract: Methods, systems, and devices are describe for signaling protocols for proximity service functions in a wireless communication system. A first wireless device may identify a group identity parameter associated with a multicast transmission of multimedia content. The first wireless device may map the identified group identity parameter to an identification parameter associated with at least one proximity service (ProSe) relay wireless device. The first wireless device may receive the multicast transmission of the multimedia content via the at least one ProSe relay wireless device based on the mapping of the identified group identity parameter to the identification parameter.

Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, some user equipment (UEs) may be configured for sidelink communications using a first radio access technology (RAT) (e.g., via a cellular network) and other wireless devices may be configured for sidelink communications using a second RAT (e.g., via a wireless local area network (WLAN)). In order to mitigate interference between communications using the first and second RAT, when a first UE is scheduled to transmit or receive a data transmission on a set of resources using the first RAT, the first UE may transmit a message using the second RAT indicating that the data transmission is to occur on the set of resources. Accordingly, the second device may receive the message and determine to refrain from communicating on the set of resources.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may identify a configuration for transmitting ranging signals in a vehicle-based communication system. The configuration may identify a plurality of channels to be used for the ranging signals and timing for the ranging signals. The wireless device may transmit the configuration to a receiver and transmit ranging signals based at least in part on the configuration. The receiver may use the ranging signals to determine a distance between the receiver and the wireless device. The receiver may use the determined distance to update positioning information or operate a motor vehicle.
