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.

Mode 1 network entity initiated network coding handover

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a plurality of sidelink transmissions associated with a spatial division multiplexing (SDM) configuration. The UE may fail to decode at least one sidelink transmission of the plurality of sidelink transmissions. The UE may transmit feedback indicating the failure to decode the at least one sidelink transmission, wherein the feedback includes an indication of at least one layer of the SDM configuration associated with the at least one sidelink transmission. Numerous other aspects are described.

Sidelink feedback for multiple transmit-receive points

Certain aspects of the present disclosure provide techniques for using physical resource blocks (PRBs) of a sidelink resource pool that, in some cases, might not belong to a sub-channel in sidelink or are assigned to a special sub-channel. When a user equipment (UE) is transmitting a sidelink communication, the sidelink communication often takes place in resource pools that include sub-channels in frequency domain and slots in a time domain. A first subset of PRBs of the resource pool may be assigned to one or more sub-channels in the frequency domain. The disclosed methods, devices, and systems provide for identifying PRBs not assigned to the first subset (e.g., remaining or unused PRBs or PRBs assigned to a special sub-channel). In some aspects of the present disclosure, the UE may use these PRBs for various purposes.

Techniques for using physical resource blocks (PRBS) in a sidelink resource pool

Disclosed are techniques for wireless communication. In an aspect, a first user equipment (UE) performs a limited beam sweep of one or more transmit beams on a second frequency band in an estimated direction from the first UE to the second UE, wherein the estimated direction is based on one or more parameters received over a previously established signaling radio bearer (SRB) on a first frequency band and/or a device-to-device discovery procedure performed on the first frequency band, receives, over the SRB, a confirmation that a data radio bearer (DRB) has been established on the second frequency band with at least one transmit beam of the one or more transmit beams, and sends, to the second UE, a data flow over the DRB on the second frequency band using the at least one transmit beam.

Beam sweeping on millimeter wave frequencies for device-to-device communications

Methods, systems, and devices for wireless communications are described. In some systems (e.g., sidelink systems, such as vehicle-to-everything (V2X) systems), wireless devices may perform dynamic resource reservations to schedule packet transmissions (e.g., data packet transmissions). Different packets may correspond to different priority levels. To support flexible resource reservation for high priority packets, wireless devices may implement techniques for preempting lower priority reservations. For example, a wireless device may identify reservations for transmitting different packets during a same transmission time interval (TTI). The device may determine whether a first or second packet has a higher relative priority and may communicate in the V2X system during the TTI according to the relative priorities. For example, a device that reserved the TTI for the lower priority packet may refrain from transmitting the packet during the TTI, while a device that reserved the TTI for the higher priority packet may transmit the packet.

Handling packets with different priorities in sidelink systems

Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) (e.g., a vehicle) may determine a configuration, including an offset value for the radar waveform, for transmitting a radar waveform for multiple radar transmitters. The UE may transmit, according to the identified configuration, a first instance of the radar waveform with a first radar transmitter. The UE may also transmit a second instance of the radar waveform with a second radar transmitter. The second instance of the radar waveform may be offset from the first instance of the radar waveform by the offset value. The Offset value may be a time offset, a frequency offset, or both. The UE may identify at least one object, and may filter our interference between the first instance of the radar waveform and the second instance of the radar waveform based on the offset.

Radar interference mitigation

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.
