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: Methods, systems, and devices are described for vehicle-to-everything (V2X) communication over one or more determined transmission time intervals (TTIs) in an unlicensed (shared) radio frequency spectrum band. A user equipment (UE) such as a vehicle may perform one or more listen-before-talk (LBT) mechanisms on the shared radio frequency spectrum and contend for access to available system resources. Upon gaining access, the UE may determine a data payload for transmission. The data type or payload may exceed a threshold and as a result, the UE may bundle a multiple TTIs for continuous data transmission. The UE may send control information, indicating a TTI bundling implementation as well as modification to the control or LBT symbols of subsequent TTIs of the data transmission, and subsequently perform data transmission over a plurality of TTIs.

Abstract: Methods, systems, and devices for wireless communication are described. A transmitting device may select an orthogonal metric based at least in part on at least one of each direction of a plurality of directions to transmit millimeter wave discovery signals or a location parameter associated with the transmitting device. The transmitting device may transmit, in the each direction of the plurality of directions, the millimeter wave discovery signals, where the each transmitted millimeter wave discovery signal has a different orthogonal metric applied that was selected based at least in part on the at least one of the each direction or the location parameter.

Abstract: Methods, systems, and devices for wireless communication are described. A 5G device may decode a control channel transmission of a safety message in a vehicle-to-everything system during a first portion of a time period. The 5G device may identify, based at least in part on the decoding, a pool of resource blocks (RBs) that are available for the time period. The 5G device may select a subset of RBs from the available pool of RBs for a transmission during a second portion of the time period.

Abstract: Various aspects of the disclosure relate to facilitating multiple hybrid automatic repeat request (HARQ) transmissions. For example, the teachings herein may be used for multiple HARQ transmissions in vehicle-to anything (V2X) communication or some other type of communication. The disclosure relates in some aspects to sending information indicative of the number of scheduling assignment (SA) symbols being sent by a device in conjunction with HARQ transmissions. The disclosure relates in some aspects to reserving resources for multiple HARQ transmissions and communicating an indication of the reserved HARQ resources.

Abstract: Wireless communication systems and methods related to signaling line-of-sight (LOS) vehicle information for improving vehicle positioning accuracy are provided. A first vehicle receives, via a sensor, sensor data indicating a line-of-sight (LOS) vehicle. The first vehicle receives, via a wireless communication device, one or more ranging signals. The first vehicle determines that a first ranging signal of the one or more ranging signals is transmitted by the LOS vehicle. The first vehicle determines a position of the LOS vehicle based on at least the sensor data and the first ranging signal. Other aspects, embodiments, and features are also claimed and described.

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: The disclosure relates in some aspects to sharing wireless communication resources. For example, a first type of device allocated to use a first resource pool may dynamically use a second resource pool allocated for a second type of device. The first type of device may use an entry criteria to determine whether to use the second resource pool. In some aspects, the entry criteria may specify that resource sharing is permitted if a ratio of resources used by devices of the second type (relative to the total resources in the second resource pool) is less than a threshold. In addition, the first type of device may use an exit criteria to determine whether to stop using the second resource pool. In some aspects, the exit criteria may specify that resource sharing should stop if a ratio of resources used by devices of the second type is greater than a threshold.

Abstract: Methods, systems, and devices for wireless communication are described. A transmitting device may identify resource blocks (RBs) used to transmit data in a data transmission. The transmitting device may determine a frequency width of a data channel in a frequency domain that is used to transmit the data based at least in part on the identified RBs. The transmitting device may dynamically determine an allocation of RBs used to transmit control information in a control channel. The allocation of RBs may be based on the frequency width of the data channel and may cause a frequency width of the control channel to match the frequency width of the data channel in the frequency domain. The transmitting device may transmit the control information in the control channel to indicate a location of the data channel.

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.
