Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a vulnerable road unit (VRU) device may determine that a parameter associated with movement of the VRU device satisfies one or more thresholds indicated in an event reporting configuration. The VRU device may transmit, to a vehicle user equipment device, an indication of an event associated with the VRU device based at least in part on determining that the parameter satisfies the one or more thresholds. Numerous other aspects are provided.

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: Certain aspects of the present disclosure provide techniques for low power channel sensing for pedestrian user equipments (P-UEs). A method that may be performed by a UE (e.g., such as a P-UE) includes determining a level of channel congestion for a channel during a first sensing duration. The method includes determining a second sensing duration and a transmission duration based on the level of channel congestion for the channel determined from the first sensing duration. The method includes sensing the channel for the second sensing duration. The method includes transmitting on the channel for the transmission duration.

Abstract: A user equipment (UE) initiates a positioning session based on ranging in a distributed system of UEs. The positioning session includes a plurality of anchor UEs with known positions that provide information including ranging information and their positions to the initiator UE in post-ranging messages. The initiator UE identifies anchor UEs that provide information that does not significantly contribute to the final position estimate for the initiator UE. The initiator UE, for example, may generate position estimates and associated accuracy levels for different subsets of anchor UEs and may use the accuracy levels to identify a subset of anchor UEs that may be used for positioning in place of the full set of anchor UEs without a significant loss of accuracy. Selected UEs are excluded from providing post-ranging messages in subsequent positioning sessions to reduce signaling overhead and improve efficiency.

Abstract: In one aspect, a method of wireless communication includes receiving, by a user equipment (UE), a downlink control signaling scheduling one or more uplink transmissions for one or more transmission resources. The method also includes determining, by the UE, to perform superposition transmission operations for at least one transmission resource of the one or more transmission resources. The method further includes transmitting, by the UE, an uplink channel data transmission and a sidelink channel data transmission in a same transmission resource, responsive to determining to perform superposition transmission operations for the least one transmission resource. Other aspects are described and claimed.

Abstract: Various aspects of the present disclosure generally relate to roadside unit relay for sidelink communications. In some aspects, a user equipment (UE) may determine a resource in which to monitor for a message from a wireless communication device, where the message is based at least in part on information from one or more vehicle to everything (V2X) messages received by the wireless communication device. The UE may monitor for the message only in the resource and receive the message in the resource. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a wake up time period corresponding to a wake up cycle, transmit a message that includes an identifier of the UE within a first resource pool during a first portion of the wake up time period based on the wake up cycle, and monitor for a paging signal from a vehicle UE during a paging occasion of the wake up time period based on transmitting the message. A vehicle UE may identify a wake up configuration for a wake up time period, receive, within a first portion of the wake up time period, a message within a resource pool that includes the identifier of the UE. The vehicle UE may transmit a paging signal within a paging occasion of the wake up time period.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) carried by a pedestrian (e.g., a P-UE) may receive control signaling that indicates a resource allocation for a sidelink channel for pedestrian to vehicle communications. The P-UE may transmit, within the resource allocation of the sidelink channel, a message that includes an identifier of the P-UE based on movement data of the P-UE being classified as pedestrian movement. The P-UE may monitor the sidelink channel for a collision warning message from a vehicle UE that includes the identifier of the P-UE based on transmitting the message. If the P-UE receives a collision warning message that includes its identifier, the P-UE may present an alert based on receiving the collision warning message.

Abstract: Methods, systems, and devices for sidelink wireless communications are described in which a user equipment (UE), such as a vehicle UE, that supports full-duplex communications may transmit a sidelink control channel during a set of time resources including scheduling information for a subsequent transmission by the UE via a first set of resources. The UE may receive a sidelink control channel during the set of time resources from a second UE that may support full-duplex communications or half-duplex communications. The sidelink control channel may include scheduling information for a subsequent transmission via a second set of time-frequency resources that at least partially overlaps with the first set of time-frequency resources. The first UE may determine that a collision will occur and may perform a resource selection procedure or may transmit a request for the second device to perform the resource selection procedure.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a signal indicating a wakeup opportunity associated with receiving one or more messages from an application and may identify a mapping between an attribute of the signal and an identifier associated with the application. The UE may determine a wakeup procedure in response to receiving the signal based on the mapping between the attribute of the signal and the identifier associated with the application.
