Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may transmit the sidelink message to a second UE via a sidelink communications channel of an unlicensed radio frequency spectrum band. The first UE or the second UE may transmit a reservation signal to retain the sidelink communication channel for corresponding feedback for the sidelink message (e.g., while the second UE generates a feedback transmission). The second UE may transmit the feedback transmission over the sidelink communication channel.

Abstract: Various aspects relate to vehicle-to-pedestrian (V2P) communication and collision avoidance using data association of data from different vehicle-to-everything (V2X) devices. In some aspects, a V2X device (e.g., a vehicle) can determine or estimate the location of a pedestrian by associating data pertaining to the pedestrian from multiple V2X devices and sensors. The association of data can reduce the uncertainties of the V2X device in the determination of the pedestrian's location. A vehicle V2X device can send out a warning indication or alert to the pedestrian or a V2X device of the pedestrian.

Abstract: Techniques described herein provide for enhanced ultra-local navigation services for V2X devices (e.g., smartphones incorporating V2X chip sets). The V2X devices can transmit vehicle information to edge network devices (e.g., roadside units). The roadside units can be deployed at intersections or along roads to collect traffic information through various sensor inputs and V2X communications with multiple vehicles. The communication between V2X devices and the edge network devices can be accomplished through wireless communication (e.g., direct PC5 interface or through local Uu interface with edge computing. The edge network devices can perform local route optimization and compute one or more recommendations (e.g., a recommend route, a recommended speed, a recommended lane). The edge network devices can transmit the one or more recommendations via a wireless communication to the V2X devices. The V2X devices can display the recommendations to a user.

Abstract: In an aspect of the disclosure, methods, a computer-readable media, and apparatus are provided. A method for wireless communication includes detecting a first object using one or more sensors. The method includes receiving one or more messages from one or more second devices indicating detection of one or more second objects. The one or more messages indicating information about the one or more second objects. The method further includes selecting information about the first object to report in a message to one or more third devices based on whether the first object corresponds to at least one object of the one or more second objects in the one or more messages.

Abstract: Certain aspects of the present disclosure provide techniques for wireless in-vehicle networking. A method that may be performed by a device in a vehicle includes wirelessly transmitting a data packet directly via a first device-to-device (D2D) communication link to another device in the vehicle; monitoring for an acknowledgment (ACK) of the data packet; deciding whether to retransmit the data packet to the other device, based on the monitoring; and wirelessly transmitting the data packet to a transmission relay, wherein an intended destination of the data packet is the other device, wherein the monitoring for the ACK comprises monitoring for a first ACK from the other device and a second ACK from the transmission relay.

Abstract: Wireless communication apparatus and methods related to wireless communication, for example, device-to-device feedback are described. In aspects, a method of wireless communication may include communicating a sidelink traffic communication using a sidelink communication structure, and communicating an allotting for sidelink feedback using at least one feedback symbol of the sidelink communication structure. In aspects, the method includes communicating, by a first wireless communication device, a sidelink feedback communication using at least one feedback symbol of the sidelink communication structure, wherein the sidelink feedback communication is associated with the sidelink traffic communication. 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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a set of resource candidates in a sidelink communication system based at least in part on a set of resource assignments for a group of other UEs in the sidelink communication system. The UE may transmit a first part of a physical sidelink control channel (PSCCH) transmission. The UE may transmit a second part of the PSCCH transmission related to the first part of the PSCCH transmission to indicate a resource candidate, of the set of resource candidates, for a transmission associated with medium access control (MAC) protocol data units (PDUs) of a particular packet. Numerous other aspects are provided.
