Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may establish, with a second UE, a first sidelink associated with a first layer 2 (L2) identifier of the second UE and a second sidelink associated with a second L2 identifier of the second UE, wherein the first L2 identifier is different than the second L2 identifier. The first UE may receive an indication associating the second UE with the first L2 identifier and the second L2 identifier. Numerous other aspects are described.

Indications associating layer 2 identifiers with a user equipment for sidelink

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

Wireless communications systems, apparatuses, and methods are provided. A method of wireless communication performed by a first sidelink user equipment (UE) may include performing a first listen-before-talk (LBT) procedure, transmitting, to a second sidelink UE based on the first LBT procedure being successful, at least one of a resource indicator indicating resources associated with a sidelink communication, wherein the resources are indicated relative to when the first LBT procedure is successful or a channel occupancy time (COT) indicator associated with COT sharing.

Resource allocation for channel occupancy time sharing in mode two sidelink communication

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

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may detect an object and determine to share position information associated with the object with one or more UEs. The UE may select a reference entity detectable by one or more other UEs and determine the position of the detected object relative to the position of the selected reference entity. The UE may transmit, to one or more second UEs, a sensor sharing message that includes the position information of the object relative to the selected reference entity and an indication of the selected reference entity. The one or more second UEs may detect the position of the reference entity and determine the location of the detected object based on the position of the reference entity and the position of the detected object relative to the position of the reference entity.

Alternative coordinate system for sensor sharing

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

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

Methods, systems, and devices for wireless communications are described. A wireless network may receive a message from a wireless device that is coupled with an aerial vehicle. The message may include a network identifier, an aerial identifier, and operational information for the aerial vehicle. The wireless network may send a message to an aerial function management system requesting that the aerial function management system authenticate an identity of the aerial vehicle. The wireless network may also request that the aerial function management system approve a flight path for the aerial vehicle. The wireless network may establish a data session with the wireless device based on an authentication of the aerial vehicle and an approval of the flight path.

Mechanism for unmanned vehicle authorization for operation over cellular networks

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a set of one or more sidelink resources, and the UE may identify wake-up signal occasions associated with the resources. The UE may monitor for wake-up signals during the wake-up signal occasions, and the UE may further monitor the associated set of one or more resources based on receiving a wake-up signal. In some examples, respective sets of one or more sidelink resources may be associated with a number of multiple-input multiple-output layers used for sidelink communications, or may indicate respective bandwidth parts used for monitoring sidelink transmissions.

Power saving techniques for sidelink communication

In one aspect, a remote device generates data for transmission to a network based on an application, selects one of a set of data routing options for routing the data to the network based on policy control information; each of the set of data routing options includes routing the data via a relay device; and transmits the data to the relay device for routing the data via the selected data routing option. In another aspect, a relay establishes a protocol data unit (PDU) session with a network for relaying data received from a remote device based on policy control information, receives data from the remote device, and transmits the data to a base station coupled to the network via the PDU session. Another aspect relates to the base station operation with respect to the above aspects.

Sidelink relay routing options for transmission of data from wireless communication device to network

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 communications are described. A user equipment (UE) and a base station may determine whether the UE is inside or outside of a vehicle with a relay device. Techniques for determining whether the UE is inside or outside of the vehicle are described herein. The UE may determine whether to camp on a cell of the relay device based on whether the UE is inside or outside the vehicle. The base station may perform connected mode mobility for the UE based on whether the UE is inside or outside the vehicle.

Techniques for efficient mobility using relay devices

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.
