Abstract: Methods and techniques are described for supporting location services for a user equipment (UE) using a location server and service based interfaces (SBIs) and SBI service operations in a Fifth Generation wireless network. The location server may be, e.g., a Location Management Function (LMF). The LMF may be in either a serving Public Land Mobile Network (PLMN) for a UE or in a Home PLMN for a roaming UE. The LMF may receive a location service request for the UE using an SBI and may communicate with another entity in the network, through a second entity and using an SBI, to obtain location information for the UE measured by the other entity. The LMF may determine a location for the UE based on the location information.

Abstract: Methods, systems, and devices for wireless communication are described. One method for wireless communication at a first device includes receiving a multicast packet from a second device, decoding control header information in the received multicast packet, determining that a decoding procedure associated with a payload of the received multicast packet is unsuccessful and transmitting a negative acknowledgement (NACK) based at least in part on the determining. The method also includes retrieving a list of transmitter identifiers. In some cases, transmitting the NACK is based at least in part on the list of transmitter identifiers. The method further includes determining a transmitter identifier associated with the multicast packet and determining that the transmitter identifier is present in the list of transmitter identifiers.

Abstract: A station (STA) receives a schedule from a reference device in a wireless network. The schedule provides a measurement time for each of one or more wireless channels. The STA tunes to a first channel of the one or more wireless channels in accordance with the schedule. While tuned to the first channel in accordance with the schedule, the STA receives a first message from a first access point (AP). The first message, which includes a time-of-departure timestamp from the reference device, is time-stamped with a time-of-arrival timestamp. The STA receives an indication of a time at which the reference device received the first message from the first AP. The STA determines its position based in part on the time-of-departure timestamp, the time-of-arrival timestamp, and the time at which the reference device received the first message.

Abstract: Various aspects of the disclosure relate to sharing vehicle sensor information. In some aspects, a requestor (e.g., a first vehicle) may transmit a request for vehicle sensor information. A responder (e.g., a second vehicle) may then respond with information sensed by the responder. For example, a requestor may unicast a vehicle-to-anything (V2X) message that requests a particular responder to share specified sensor information. As another example, a requestor may broadcast a vehicle-to-anything (V2X) message that requests any responder that meets a response criterion (or response criteria) to share specified sensor information.

Abstract: Techniques are described for wireless communication. A method for wireless communication at a first base station (e.g., corresponding to, associated with, or included in a first cell) includes receiving location information from a vehicle; identifying, based at least in part on the location information, a plurality of cells from which to broadcast a location message associated with the vehicle, where the plurality of cells include at least a cell of a second base station; and communicating with at least the second base station regarding a broadcast of the location message. A method for wireless communication at a vehicle include transmitting location information from the vehicle to a base station on an access stratum (AS) layer, and transmitting location message information to the base station. 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 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: Example methods and apparatuses for managing polling in devices implementing proximity services are presented. For instance, an example method of polling management in a ProSe system is presented, which includes receiving, at a network entity, a polling message from a first UE. In addition, the example method may also include receiving, at the network entity and after receiving the polling message, one or both of a first location report associated with the first UE and a second location report associated with a second UE. Furthermore, the example method may include determining whether to generate a polling response message upon receiving one or both of the first location report and the second location report, wherein the polling response message includes a next polling time for the first UE that is based on a location reporting schedule associated with one or both of the first UE and the second UE.

Abstract: Methods, systems, and devices are described for utilization of an unlicensed radio frequency spectrum band for performing a ranging procedure. Performance of the ranging procedure may be triggered by a signal transmitted in a licensed radio frequency spectrum band. While conventional ranging in Long Term Evolution (LTE) communications, for example, using the licensed radio frequency spectrum band may be limited to a 10 MHz bandwidth, using the unlicensed radio frequency spectrum band for ranging may allow use of a wider bandwidth, such as 100 MHz or greater. Use of the wider bandwidth may result in more accurate ranging measurements (e.g., time-of-arrival estimation).

The UE may determine a discontinuous reception configuration for the group of UEs based at least in part on the transmission schedule. The discontinuous reception configuration may include a discontinuous reception schedule for the group of UEs. The UE may transmit, to the group of UEs, the discontinuous reception configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure one or more user equipments (UEs) with one or more timers, such that the UEs may switch directions for a communication mode for the duration of a timer and during a discontinuous cycle. The UEs may activate the timers and may perform the switching operation during the active duration of a discontinuous cycle. A UE may transmit a sidelink message during a transmission on duration (TX-On). The UE may activate a timer and switch to a receive mode. Similarly, the second UE may receive the sidelink message during a reception on duration (RX-On) and may activate the timer. The second UE may switch to a TX-On mode for an on duration of a TX-On cycle to transmit a sidelink response.
