Abstract: Aspects are provided which allow a UE to switch between feature data extraction models in order to provide adaptive feature data of dynamic, potential LOS obstacles for improved beam blockage prediction performance (or other functions) at the network node. Initially, the network node receives first feature data from a UE based on a first data extraction model of the UE. The network node transmits a message instructing the UE to switch from the first data extraction model to a second data extraction model of the UE based on a state of the UE. In response to the message, the UE determines to switch from the first data extraction model to the second data extraction model and transmits, to the network node, second feature data based on the second data extraction model. The network node may then determine a beam blockage prediction in response to the second feature data.

Abstract: Aspects relate to techniques for enabling a UE to detect a potential mistrusted UE that may be sharing inaccurate sidelink assistance information with other UEs. In an aspect, a first UE may receive a plurality of sidelink assistance information from other UEs. The first UE can further identify an amount of the plurality of sidelink resources for which a second UE provides respective inconsistent sidelink assistance information with respect to other UEs. In response to the amount exceeding a mistrust detection threshold, the first UE can transmit a report indicating that the second UE is a potential mistrusted UE to a centralized node. Based on the received reports associated with the second UE, the centralized node can transmit a mistrust indication indicating that the second UE is an actual mistrusted UE with respect to subsequent sidelink assistance information associated with the second UE.

Abstract: Certain aspects of the present disclosure provide techniques for wireless in-vehicle networking. A method that may be performed by a device in a vehicle includes wirelessly transmitting a data packet directly via a first device-to-device (D2D) communication link to another device in the vehicle; monitoring for an acknowledgment (ACK) of the data packet; deciding whether to retransmit the data packet to the other device, based on the monitoring; and wirelessly transmitting the data packet to a transmission relay, wherein an intended destination of the data packet is the other device, wherein the monitoring for the ACK comprises monitoring for a first ACK from the other device and a second ACK from the transmission relay.

Abstract: Methods, systems, and devices for wireless communications are described. The method, system, and apparatus may include managing the operation mode of a user equipment in vehicle-to-everything communication. In some aspects, a user equipment may transmit an inactive request message (or a request message) to a base station to indicate the user equipment is switching from a base station scheduling mode (or a radio access network node scheduling mode) to a peer user equipment scheduling mode (or a roadside unit scheduling mode). The user equipment may receive an acknowledgment message from the base station indicating a state change to allow the peer user equipment scheduling mode. In some cases, the user equipment may receive an area identifier from the base station, and the area identifier may indicate an area where the peer user equipment scheduling mode is allowed.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting user equipments (UEs) may transmit a sidelink indication signal including a sequence (for example, wakeup signal or go-to-sleep signal) for a receiving UE to determine whether to monitor for scheduling sidelink control information (SCI) messages in one or more sidelink discontinuous reception (DRX) on durations that overlap in time. The receiving UE may determine (for example, based on an initial value in the sequence, the resource on which the sequence was received, among other examples) a location of an on duration, and may perform a DRX operation (for example, may wake up or may go to sleep) during the on duration.

Abstract: 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.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) of a group of UEs may receive, from a group member of the group of UEs, traffic information including a transmission schedule associated with traffic of the group member UE. The UE may determine a discontinuous reception configuration for the group of UEs based at least in part on the transmission schedule. The discontinuous reception configuration may include a discontinuous reception schedule for the group of UEs. The UE may transmit, to the group of UEs, the discontinuous reception configuration.

Abstract: Methods, systems, and devices for wireless communication are described. A network entity (e.g., a roadside unit, a relay node, a user equipment (UE), or a base station) may use a network coding indication in a transmission that indicates the transmission is a network coded transmission (i.e., the transmission includes retransmitted packets from UEs in a wireless communications system). The indication may be explicitly or implicitly signaled in control information. For example, control information may include a field that explicitly identifies the network coded transmission. Additionally or alternatively, the control information may implicitly identify the network coded transmission, such as by indicating a format of control signaling or including a special source identifier in the network coded transmission. The network coded transmission may also include one or more network coding parameters that identify parameters of the original transmission.

Abstract: Methods, systems, and devices for wireless communications are described that provide for directional quality of service (QoS) targets of a user equipment (UE) for directional communications to multiple UEs in multiple directions. An application layer of the UE may provide data with multiple different directional QoS targets, that may be mapped to multiple QoS data flows that are each configured with different directional QoS targets such as direction and priority associated with the direction. The data may be duplicated for each of the multiple QoS data flows having different QoS parameters, and each QoS data flow may be transmitted in a different direction using a different beam.
