Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit, in a first slot within a channel occupancy time (COT), a first communication; determine whether one or more transmission criteria are satisfied for transmission of a second communication in a second slot within the COT; and selectively transmit the second communication in the second slot within the COT based at least in part on a result of determining whether the one or more transmission criteria are satisfied. Numerous other aspects are provided.

Discontinuous transmission in shared channel occupancy time for sidelink communication in unlicensed spectrum

An improved manner of transmitting and receiving messages in V2X/V2V/D2D is presented in which a transmitting device determines a geographic location of the mobile transmitting device and generates a message for a service group having a group ID associated with the service group, the message comprising a first indication of a geographic area associated with the message, the geographic area based at least in part on the geographic location of the transmitting device. Then, the apparatus transmits the message to the service group, e.g., via V2X/V2V/D2D communication. A receiving device then determines its geographic location and determines whether to send a feedback for the message based on the first indication of the geographic area associated with the message and the geographic location of the receiving device.

Transmission with indication of geographic area

Apparatus, methods, and computer-readable media for facilitating interruption handling in satellite-based communications are disclosed herein. An example method for wireless communication at a UE includes determining an interruption for a satellite-based communication link based in part on UE location information and blockage information of an obstruction that blocks LOS propagation for the satellite-based communication link. The example method also includes refraining performance of one or more communication link correction procedures for a time period associated with the interruption.

Techniques to handle interruption in satellite-based communications

Certain aspects of the present disclosure provide techniques for wireless communications in a vehicle-to-everything (V2X) system. An example method generally includes receiving, from a user equipment (UE) through a serving network entity, a request for information from the V2X application server, wherein the request includes an indication of a type of the requested information and a location of the UE; identifying one or more parameters for transmission of the requested information to the UE via a transmitter UE; and transmitting, to the serving network entity, the requested information for transmission to the UE through the transmitter UE based on the identified parameters.

High reliability communication in vehicle-to-everything (V2X) systems on sidelink and radio network link interfaces

Methods, systems, and devices for wireless communications are described. In some cases, an application enabler layer (e.g., a vehicle-to-everything (V2X) application enabler (VAE) layer), may identify a congestion control configuration that includes capabilities for collecting operation information. The application enabler layer may receive, from a set of user equipment (UEs), the operation information in accordance with the capabilities. Then, the application enabler layer may generate congestion control instructions for one or more UEs of the set of UEs based on the received operation information. Additionally or alternatively, an application enabler architecture layer (e.g., a service enabler architecture layer for verticals (SEAL)) may identify a congestion control configuration including capabilities for collecting operation information and monitor sidelink performance for the set of UEs in accordance with the capabilities. The application enabler architecture layer may identify a congestion status for a communication type based on monitoring the sidelink performance.

Congestion control by a sidelink midlayer framework

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.

Radio vehicle-to-anything negative acknowledgement based multicast

During device-to-device communication between two devices, a communication transmitted from a first UE to a second UE may not be reliably received by the second UE if the first UE is traveling at high speed. Therefore, a travel speed of a transmitting UE may be considered in determining a transmission configuration. According to an aspect, the UE may determine a travel speed of the UE. The UE may determine, based on the travel speed of the UE, a transmission configuration of the UE for device-to-device communication. The UE may transmit the device-to-device communication based on the transmission configuration.

Supporting high speeds in vehicle-to-vehicle communication

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.

Reference signal patterns based on relative speed between a transmitter and receiver

Certain aspects of the present disclosure provide techniques for techniques for sensor data sharing. Certain aspects provide a method for wireless communication by a first wireless device. The method generally includes receiving, from one or more sensors, corresponding one or more raw sensor data sets and transmitting, to a second wireless device, at least one message comprising information regarding an object detected based on processing the one or more raw sensor data sets, wherein the information includes one or more characteristics of the object derived based on processing the one or more raw sensor data sets, wherein: when one or more conditions are met, the information further includes at least one raw sensor data set of the one or more raw sensor data sets; and when the one or more conditions are not met, the information does not include any raw sensor data.

Conditional vehicle to everything (V2X) sensor data sharing

An improved manner of transmitting and receiving messages in sidelink communication is presented in which a wireless device receives sidelink control information (SCI) that indicates a zone ID associated with a sidelink message. The wireless device determines a location of the wireless device and determines whether to send feedback for the sidelink message based, at least in part, on the zone ID associated with the sidelink message and the location of the wireless device. The feedback may include hybrid automatic repeat request (HARQ) feedback, and the sidelink message may include a groupcast message. The wireless device may further receive an indication of an intended range in the SCI and may determine whether to send the feedback based on a combination of the zone ID and the intended range for the sidelink message.

A method of assisting joint network entity/user equipment and user equipment/user equipment (NE/UE-and-UE/UE) ranging includes: transmitting, from a first UE to a network entity, a capability indication that indicates a capability of the first UE to serve as an anchor UE for joint NE/UE-and-UE/UE ranging; obtaining, at the first UE, a location of the first UE; transmitting, from the first UE, the location of the first UE; transmitting, from the first UE to the network entity, at least one indication that a second UE is in a line of sight of the first UE or that the second UE is in close proximity to the first UE; and transmitting, from the first UE, at least one of a first positioning reference signal to the second UE, or a measurement report indicating a measurement of a second positioning reference signal received by the first UE from the second UE.

Joint network entity/user equipment-and-user equipment/user equipment ranging

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a first transmission, wherein the first transmission includes information identifying a window, and wherein the UE is to transmit at least part of a second transmission in the window; and transmit at least part of the second transmission in the window. Numerous other aspects are provided.

Communication using semi-persistent scheduling and sensing

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus of a vehicle may include one or more meta-surfaces disposed on one or more glass surfaces of the vehicle. The one or more meta-surfaces may be configured to redirect electromagnetic waves incident on the one or more meta-surfaces toward one or more target points within the vehicle.

Metasurface enabled in-vehicle link enhancement

Methods, apparatuses, and computer-readable mediums for wireless communication are disclosed by the present disclosure. In an aspect, an application layer in a user equipment (UE) receives, from an access layer in the UE, a quality of service (QoS) indication comprising a metric that represents a quality of one or more radio bearers used for a vehicular communication with one or more other UEs. The application layer performs a transmission control over the vehicular communication based on the QoS indication.
