Abstract: Methods, apparatuses, and computer-readable mediums for wireless communication are disclosed by the present disclosure. In an example, a relay node may determine a first predicted motion of a first vehicle including a first wireless communication device having a first established communication channel with the relay node. The relay node may determine that the first predicted motion will trigger a communication condition for the first vehicle and a second wireless communication device having a second established communication channel with the relay node. The relay node may reserve radio resources for a third communication channel between the first wireless communication device and the second wireless communication device.

Abstract: Methods, systems, and devices for wireless communications (e.g., vehicle to everything systems) are described relating to an adaptive design of demodulation reference signals (DMRS) density based on user equipment (UE) velocity. A UE may send assistance information to a transmitting UE to help identify a DMRS pattern based on the relative speed between the two UEs. Also, the transmitter may determine the adaptive DMRS pattern based on its speed without information of the receiver's speed. The transmitter may indicate the adaptive DMRS pattern in control information to the receiver. A base station may receive assistance information, and the base station may determine the adaptive DMRS pattern to be used by the transmitting UE based on the received assistance information and then indicate the adaptive DMRS pattern to the transmitting UE. A UE may determine an adaptive DMRS pattern to use based on feedback from the receiving UE.

Abstract: A method, apparatus, and computer-readable medium at a transmitting user equipment (UE) in a distributed cellular vehicle-to-everything environment are disclosed to achieve communications between the distributed UEs with high reliability and low latency. A transmitting UE can configure an ultra-reliable low-latency communication (URLLC) transmission unit by configuring a URLLC channel indicator, a URLLC transmission indicator, a URLLC control channel, and URLLC data portion. The UE can transmit the configured URLLC transmission unit in punctured OFDM symbols within a regular subframe to a receiving UE in the distributed C-V2X environment.

Abstract: Methods, systems, and devices for wireless communications are described in which a receiving device, such as a receiving user equipment (UE) or vehicle, may provide channel state information (CSI) in which two or more parameters associated with the CSI are provided in a single joint indication. A transmitting device may transmit one or more reference signals and the receiving device may perform one or more measurements on the received reference signal(s). Based on the one or more measurements, the receiving device may determine one or more CSI parameters, such as a rank indicator, channel quality indicator, precoding matrix indicator, or combinations thereof, that may be provided to the transmitting device in a joint indication.

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.

Abstract: Methods, systems, and devices for wireless communications are described. A device, which may be otherwise known as user equipment (UE) may support sidelink communications, for example, such as device-to-device (D2D) communications, vehicle-based communications, which may also be referred to as vehicle-to-everything (V2X) communications, vehicle-to-vehicle (V2V) communications, and the like. To mitigate or decrease collisions or other interference on resources (e.g., time and frequency resources) used by other UEs in sidelink communications, a UE may determine a blind retransmission of a packet, determine that the packet satisfies one or more conditions based in part on the blind retransmission, and transmit feedback signal relating to the blind retransmission of the packet.

Abstract: Methods, systems, and devices for wireless communications are described in which a transmitting user equipment (UE) may determine a data packet to transmit to another UE and determine a set of candidate resources for transmission of the data packet based on a set of time-frequency resources that are allocated for UE-to-UE communications. A resource reservation signal (RRS) may be transmitted to indicate to other UEs that the set of candidate resources have been reserved by a UE. The RRS may be transmitted such that the RRS may be differentiated from other regular transmissions based at least in part on information provided by a control channel associated with the RRS or a payload of a transmission that includes the RRS. The RRS may indicate one or more of a size of an allocation of the resources and multiple locations of the resources within a time-frequency resource pool.

Abstract: A user equipment (UE) may communicate with one or more other UEs using multiple transmissions in a device-to-device (D2D) communications deployment. A number of UEs may be configured with D2D resources, and a transmitting UE may identify available D2D resources from the configured resources. The transmitting UE may identify a resource for a first transmission of a D2D transmission from the available D2D resources, and may identify a second resource for a second transmission of the D2D transmission. The second transmission may be a blind HARQ transmission that may be transmitted to enhance the likelihood that one or more receiving UEs successfully receive the transmission. In some examples, the second resource may be identified based on other available resources within an predetermined time window around the first transmission.

Abstract: Methods, systems, and devices for wireless communications are described that provide for dynamic resource avoidance and slot aggregation. The described techniques enable a user equipment (UE) in a vehicle-to-everything (V2X) system to select resources for varying transmission of a data packet (e.g., over multiple slots). The UE may determine a set of candidate transmission time intervals (TTIs) for transmission of the data packet based on a resource map, which may involve selecting resources that are unoccupied by other UEs as indicated by the resource map or preempting other UEs based on traffic priority or latency. The UE may transmit a reservation indication indicating resources to be reserved for subsequent transmissions (e.g., retransmission) and a UE receiving the reservation indication may update its resource map.
