This disclosure provides systems, methods, and devices for wireless communication that support visual sensing for positioning. In a first aspect, a method of wireless communication includes receiving a first image of an object from an image capture device. The method also includes receiving location information that includes a coordinate point, a position of the UE determined based on the coordinate point, or a combination thereof. The coordinate point is generated based on a relative orientation between the UE and a network entity, and a matched pair of points including a first point of the first image and a second point of a second image of the object captured by the network entity. Other aspects and features are also claimed and described.

Visual sensing for positioning

Aspects presented herein improve congestion control mechanism for UEs with multiple TRPs, where at least one of the SL RSSI measurement, the CBR measurement, the CR evaluation and/or the congestion control mechanism for the UE is optimized. In one aspect, the apparatus evaluates a CR for each TRP of a plurality of TRPs at the UE. The apparatus determines whether the UE is allowed to transmit on one or more of the TRPs of the plurality of TRPs based at least on the evaluated CR for each TRP of the plurality of TRPs and on at least one CR limit. The apparatus transmits on at least one TRP of the one or more of the TRPs based on the determination whether to transmit on the one or more TRPs.

Congestion control for sidelink communication with multi-TRP

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

Aspects relate to managing a device-to-device communication link via radio resource control (RRC) layer signaling. In an example operation, a first wireless communication device establishes a unicast link with a second wireless communication device over a device-to-device communication interface and determines that the unicast link is to be reconfigured with at least one updated parameter. The first wireless communication device then sends a link reconfiguration request to the second wireless communication device via a first RRC message over the communication interface. The first RRC message includes the at least one updated parameter. The first wireless communication device receives a link reconfiguration response from the second wireless communication device via a second RRC message over the communication interface based on the link reconfiguration request and determines whether to reconfigure the unicast link using the at least one updated parameter based on the received link reconfiguration response.

Unicast link management via radio resource control signaling

Certain aspects of the present disclosure provide a method for wireless communications by a transmitter user equipment (UE). The transmitter UE generates a message authentication code, based on information within a sidelink master information block (SL-MIB) and a key shared between the transmitter UE and a receiver UE. The transmitter UE transmits a sidelink broadcast channel (SL-BCH) transmission carrying the SL-MIB and the message authentication code.

Secure timing for sidelink systems

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE, an indication of a first reservation of a first resource associated with a first relay link of a UE-to-UE relay, wherein the first reservation is based at least in part on a second reservation of a second resource associated with a second relay link of the UE-to-UE relay. The UE may perform a sidelink communication in accordance with the first resource. Numerous other aspects are described.

Techniques for resource reservations for user equipment relays

Aspects presented herein relate to methods and devices for wireless communication of an apparatus, e.g., a UE. In one aspect, the apparatus may detect at least one conflict in a set of reserved resources between two or more sidelink (SL) resource reservations, each of the two or more SL resource reservations being associated with each of two or more UEs. The apparatus may also configure at least one of an indication of the at least one conflict or at least one resource reservation forwarding message. The apparatus may also transmit, after detecting the at least one conflict in the set of reserved resources, one or more of at least one resource reservation forwarding message or an indication of the at least one conflict.

Collision indicators for sci forwarding information and sci forwarding triggering

Methods, systems, and devices for wireless communications are described. A network entity may partition one or more user equipments (UEs) within a target area into groups and assign one UE per set to be a lead UE to aggregate shared sensor data without large sidelink overhead from multicasting all sensor data or uplink signaling overhead from aggregating data at the network entity. For example, the network entity may transmit, and a UE may receive, a partition request message corresponding to a hierarchical partitioning scheme. The UE may transmit a partition request feedback message in response to the partition request message, which may include an indication of the availability of the UE to act as the lead UE. The UE may receive a partition assignment message from the network entity, which may include a partition between sets of UEs and an indication of the lead UE for the set of UEs.

Hierarchical partitioning and sensor data aggregation in perceptive wireless communications systems

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. A base station may identify a first radio bearer to be used for sensing operations and a second radio bearer to be used for data communications. The base station may transmit, to a user equipment (UE), a control message indicating the first radio bearer and the second radio bearer, where the first radio bearer and the second radio bearer may be indicative of a resource allocation for the sensing operations and the data communications. The UE may perform the sensing operations in accordance with a resource allocation, and perform the data communications in accordance with the resource allocation, where the resource allocation may be based on the first radio bearer and the second radio bearer. The UE may perform the sensing operations and the data communications in accordance with a joint communication and radar (JCR) system.

Techniques for allocating resources for communications and radar sensing

In some aspects of the disclosure, a method of wireless communication includes performing a first wireless transmission using a plurality of transmission and reception points (TRPs) of a vehicle. The first wireless transmission is performed based on a first transmit power allocation among the plurality of TRPs. The method further includes, in response to the first wireless transmission, receiving one or more feedback signals indicating a receive status of the first wireless transmission at one or more devices. The method further includes performing a second wireless transmission using the plurality of TRPs based on a second transmit power allocation among the plurality of TRPs. The second transmit power allocation is determined based on at least one received signal strength of the one or more feedback signals.

Transmit power adjustment for a vehicle with multiple transmission and reception points

Aspects relate to techniques for sidelink transmissions scheduled by network entities. A UE may receive a resource reservation message from a transmitting UE indicating resources granted by a network entity for a first sidelink transmission. The UE may detect a conflict between the first sidelink transmission and a second sidelink transmission and transmit a conflict indication in response to detecting the conflict. The UE may transmit the conflict indication to the transmitting UE or to the network entity. In some examples, the transmitting UE receiving the conflict indication may report the conflict to the network entity.

Coordinated sidelink communication

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter user equipment (UE) may identify beamforming information for transmitting a pre-reservation signal that indicates a set of non-preferred resources associated with a data transmission. The UE may transmit, to a receiver UE in accordance with the beamforming information, the pre-reservation signal that indicates the set of non-preferred resources associated with the data transmission. Numerous other aspects are described.

Sidelink resource reservation using non-preferred resource signaling

Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive, from a second UE, a first sidelink synchronization signal (SLSS) at a first transmission-reception point (TRP) and a second TRP different from the first TRP. The first UE may perform a first set of measurements on the first SLSS received at the first TRP and a second set of measurements on the first SLSS received at the second TRP. The first UE may then transmit, to a third UE, a second SLSS based at least in part on the first set of measurements, the second set of measurements, or both, satisfying one or more measurement thresholds.

Techniques for sidelink synchronization signal transmission with multi-transmission and receive point (TRP) user equipment (UES)

A first device may communicate an SL NC TB with a second device. At least one of the first device and the second device may be a UE. The first device may transmit, to a network entity, a first message having a first location information that indicates a movement of the UE from a first zone to a second zone. The first message may have a first location information associated with the UE. The UE may be in SL communication with a first encoder in the first zone. The network entity may obtain, from the first device, the first message. The network entity may initialize an NC handover of the UE to a second encoder of the second zone in response to the first location information indicating a movement of the UE from the first zone to the second zone.
