Abstract: Apparatus, methods, and computer-readable media for facilitating relay of superpositioned sidelink and uplink transmission are disclosed herein. An example method for wireless communication at a first communication device includes receiving, from a UE, a MUST transmission including a base layer and an enhancement layer, the base layer comprising a first message for a second communication device and the enhancement layer comprising a second message for the first communication device. The example method also includes decoding the base layer of the MUST transmission to obtain the first message. Additionally, the example method includes receiving a feedback message from the second communication device indicating that the second communication device did not successfully receive the first message. The example method also includes retransmitting the first message to the second communication device in response to the feedback message from the second communication device.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may include a radar which is used for object detection, such as a vehicle UE detecting other vehicle UEs in a vehicle-to-everything (V2X) communications system. The UE may be configured for coordinated interference, where radars transmit a common waveform while applying different delays to prevent negative co-channel interference effects, such as false or ghost targets. The techniques described herein support configuring a common configuration for network-assisted coordinated interference by considering capabilities of UEs and radars within a geographic area controlled by a network entity. The network entity may identify and indicate a waveform configuration which is used by radars within the geographic control area of the network entity.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first UE may mark a packet with a first QoS indicator, the packet being associated with a communication between the first UE and a second UE, the first QoS indicator being associated with an uplink between the first UE and a first network node, and the first QoS indicator indicating a mapping to a second QoS indicator associated with a downlink between a second network node and the second UE. The UE may transmit, to the first network node via the uplink, the packet. Numerous other aspects are described.

Abstract: Systems and techniques are provided for wireless communications. A first UE can determine assistance information corresponding to one or more uplink (UL) transmissions of the first UE, the assistance information indicative of a periodicity of the one or more UL transmissions. The one or more UL transmissions can be vehicle-to-everything (V2X) UL transmissions of the first UE. The first UE can transmit the assistance information to a network entity. The network entity can determine a discontinuous reception (DRX) configuration for a second UE based on the assistance information, the DRX configuration indicative of a DRX on-duration. The second UE can receive information indicative of the DRX configuration from the network entity. The second UE can receive, from the network entity and during the DRX on-duration, a downlink transmission associated with the first UE. The downlink transmission can be a V2X downlink transmission.

Abstract: In various embodiments supporting directional security, a user equipment (UE) may receive from a network device a noise resource allocation including an indication of a noise direction and a noise parameter, generate a noise signal based at least in part on the noise parameter, and transmit the noise signal in the noise direction while transmitting a communication transmission signal in a different direction from the noise direction. In various embodiments, a network device may determine a geographic zone of interest, select one or more reconfigurable intelligent surfaces (RISs) associated with the geographic zone of interest, selecting one or more noise transmitting UEs, control the one or more noise transmitting UEs to transmit at least one noise signal, and control the one or more RISs to steer the at least one noise signal into the geographic zone of interest.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive, from a second UE, sidelink control information for performing full-duplex communications with the second UE. The sidelink control information may include an indication of resources reserved by the second UE, an indication of one or more transmit beam directions associated with the resources reserved by the second UE, or both. The first UE may receive, via the resources reserved by the second UE, a first message using a first receive beam based on the sidelink control information. The first UE may transmit, via the resources reserved by the second UE, a second message using a first transmit beam of the first UE, a direction of the first transmit beam being different from a direction of the first receive beam.

Abstract: 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.
