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.

Radio vehicle-to-anything negative acknowledgement based multicast

Methods, apparatuses, and computer program products for radar devices are provided. A radar device may detect an interfering radar signal from a second radar device that interferes with measurement of a return of a radar signal from the first radar device. The radar device may perform a timing adjustment action in response to detecting the interfering radar signal from the second radar device.

Interference relocation in radar applications to mitigate inter-radar interference

Aspects present herein relate to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. The apparatus may receive, from a base station, a security mode command message associated with secure sidelink communication with at least one other UE. The apparatus may also identify, based on the security mode command message, at least one of a RRC encryption key or a user plane encryption key. Additionally, the apparatus may receive, from the base station, an indication of at least one of a common base key or the RRC encryption key. The apparatus may also identify a physical layer sidelink encryption key based on at least one of the common base key or the RRC encryption key, the physical layer sidelink encryption key being associated with the secure sidelink communication with the at least one other UE.

Secure sidelink 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

Some aspects provide a method for wireless communication by a first wireless device. The method generally includes transmitting control information regarding at least one of scheduling or configuration of a channel state information (CSI) report to be transmitted by the first wireless device. The method generally includes generating the CSI report based on one or more CSI reference signals (CSI-RSs) received by the first wireless device. The method generally includes and transmitting the CSI report in accordance with the control information.

CSI report setting by the CSI-transmitting user equipment

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive, from one or more user equipments (UEs), feedback information associated with a distributed sensing procedure. The network node may select, based at least in part on the feedback information, a set of UEs to be included in the distributed sensing procedure. The network node may transmit, to the set of UEs, an indication of configuration parameters associated with the distributed sensing procedure. Numerous other aspects are described.

Distributed sensing with low-resolution analog-to-digital converters

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain a common key. The UE may communicate with one or more other UEs using a lower layer groupcast key that is based at least in part on the common key, a parameter, and at least one of a group identifier or a destination identifier. Numerous other aspects are described.

Lower layer security for groupcast communication

This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for adapting a radar transmission based on a congestion level. A wireless device, such as a radar device, a UE, a base station, a vehicle, etc., may detect a congestion level of a wireless communication environment that includes the wireless device. The wireless device may have at least one of a first FOV or a first range within the wireless communication environment. The wireless device may transmit, based on the congestion level exceeding a threshold, a radar signal that corresponds to the wireless device having at least one of a second FOV or a second range in the wireless communication environment that is smaller than the at least one of the first FOV or the first range.

Adapting a radar transmission based on a congestion level

Disclosed are techniques for wireless communication. In an aspect, a first user equipment (UE) establishes a radio resource control (RRC) connection for a communication session with a second UE, establishes a signaling radio bearer (SRB) for the communication session with the second UE on a first frequency band, sends, to the second UE over the SRB on the first frequency band, a first RRC message to establish a data radio bearer (DRB) for the communication session on a second frequency band, the first RRC message including one or more parameters for establishing the DRB on the second frequency band, and configures the DRB on the second frequency band based on the one or more parameters in the first RRC message and/or a device-to-device discovery procedure performed in the first frequency band.
