Abstract: Methods, systems, and devices for wireless communications are described. A communication device, which may be otherwise known as user equipment (UE), may receive a data transmission and determine a feedback timing value based on the data transmission. The communication device may determine a feedback resource set in a resource pool associated with one or more slots based on the feedback timing value, and transmit a feedback using the feedback resource set associated with the one or more slots and corresponding to the feedback timing value.

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 communications are described. Some wireless communications systems support beamforming to improve the reliability of transmissions from a transmitting device to a receiving device. In some cases, a wireless device broadcasts information using beamforming. In such cases, in order to limit the overhead and power consumption associated with the broadcast, the wireless device utilizes the techniques described herein for broadcasting information using beamforming. In particular, rather than broadcasting large amounts of data in a beam-sweep, a wireless device broadcasts a relatively lightweight signal in a beam-sweep to first identify a receiving device and/or a suitable beam for communicating with a receiving device. Once the transmitting device identifies the receiving device and/or the suitable beam, the transmitting device broadcasts the data to be received by the receiving device.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine that a profile for vehicle-based sidelink communications supports packet duplication using a set of carrier frequencies. The UE may transmit a message to a base station that identifies the profile and the set of carrier frequencies. The UE may receive a configuration message from the base station that identifies a packet duplication configuration. The UE may transmit, based on the packet duplication configuration, a request to the base station for resources to perform the vehicle-based sidelink communications, the request comprising one or more buffer status report (BSRs), wherein each BSR identifies a carrier frequency for the BSR and a logical channel group identifier that identifies the BSR as being for packet duplication.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first set of synchronization signals from a first synchronization source and may receive a second set synchronization signals from a second synchronization source, where the UE determines a first priority for the first synchronization source based on a first identification (ID) associated with the first set of synchronization signals and a second priority for the second synchronization source based on a second ID associated with the second set of synchronization signals. Accordingly, the UE may then select the first synchronization source or the second synchronization source based on which synchronization source has a higher priority and communicate with the selected synchronization source (e.g., via sidelink communications).

Abstract: In an example, a method for wireless communications by a first wireless device, is disclosed comprising obtaining information regarding an environment for wireless communications between the first wireless device and at least one second wireless device and adjusting one or more operating parameters for the wireless communications, based on the information. As described herein, information from one service or application in a first RAT is used by the first wireless device to enhance performance in another service or application in a second RAT by the first wireless device.

Abstract: The present aspects relate to device-to-device (D2D) relaying in a wireless communication system. In an aspect, a relay user equipment (UE) may receive, on a downlink channel from a network entity, at least one indication including resource allocation information for at least one of the relay UE or a remote UE. The relay UE may further transmit, on a sidelink channel to the remote UE, the resource allocation information of the remote UE. In another aspect, a remote UE may receive, on at least one sidelink channel, resource allocation information from a relay UE, the resource allocation information indicating one or more resources allocated for sidelink communication for the remote UE. The remote UE may further transmit, on one or more sidelink channels, data to the relay UE in accordance with the one or more resources allocated for sidelink communication.

Abstract: Methods, systems, and devices for wireless communications are described. In one example, a method includes receiving broadcast information from a base station that identifies types of resources for vehicle-based sidelink communications that are supported by the base station and transmitting a request to the base station for resource scheduling information to perform a vehicle-based sidelink communication based on the broadcast information. In some cases, the request includes an indication of a type of resources for the vehicle-based sidelink communication supported by the base station and a quality of service (QoS) metric associated with the vehicle-based sidelink communication. In some cases, the method further includes receiving, in response to the request, a response from the base station that comprises the resource scheduling information to perform the vehicle-based sidelink communication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a client device may receive a discovery signal from a host device; determine whether to use a receive timing from the host device, an internal timing of the client device, or a combination of the receive timing and the internal timing to configure a reference timing; configure the reference timing, for transmission of a response to the discovery signal, using the receive timing from the host device, the internal timing of the client device, or the combination of the receive timing and the internal timing based at least in part on the determination of whether to use the receive timing, the internal timing, or the combination of the receive timing and the internal timing; and transmit the response to the host device using the configured reference timing. Numerous other aspects are provided.
