Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a second UE and via a receive beam of the first UE, an inter-UE coordination (IUC) request, wherein the IUC request is based at least in part on a transmit beam of the second UE that is associated with an intended transmission of the second UE. The UE may transmit, to the second UE, IUC information that indicates preferred resources or non-preferred resources for the intended transmission, wherein the IUC information is based at least in part on a channel sensing by the first UE. Numerous other aspects are described.

Abstract: Apparatus, methods, and computer-readable media for facilitating improvement in sensing for unicast sidelink communication are disclosed herein. An example method for wireless communication at a first user equipment (UE) includes receiving, from a second UE over a sidelink channel, a first transmission comprising sidelink control information (SCI). In some aspects, the SCI indicates a resource reservation of the second UE. The method includes obtaining measurements of the first transmission and determining whether the measurements exceed a reference threshold. The method includes determining whether the SCI includes an indication that the second UE is following a first resource recommendation of a third UE that is an intended receiver of the second UE when the measurements exceed the reference threshold. The method also includes ignoring the resource reservation of the second UE when the SCI includes the indication that the UE is following the first resource recommendation of the third UE.

Abstract: Methods, systems, and devices for wireless communications are described. To improve sidelink reservation schemes. a first user equipment (UE) may indicate its preferences for sidelink resources to a second UE that may select sidelink resources for sidelink messages based on the indicated preferences. For example, the first UE may monitor a first set of sidelink resources for sidelink control information (SCI) to determine which sidelink resources of a second set of sidelink resources are available. Based on the monitoring, the first UE may generate a bitmap that indicates the first UE's preferences for the sidelink resources of the second set and may transmit a coordination message to the second UE that includes the bitmap. The second UE may receive the coordination message and transmit, to the first UE, one or more sidelink messages using one or more sidelink resources of the second set selected based on the indicated preferences.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a road-side unit (RSU) may join a first sidelink (SL) ranging session between a first user equipment (UE) and a second UE. The RSU may perform SL ranging with the first UE to determine first ranging information comprising at least a RTT to the first UE. The RSU may perform SL ranging with the second UE to determine second ranging information comprising at least a RTT to the second UE. The RSU may send the first ranging information and the second ranging information to at least one of the first UE or the second UE, or calculate a range between the first UE and the second UE based on the first ranging information and the second ranging information, and send the range to at least one of the first UE and the second UE.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may be associated with a reconfigurable surface for reflecting transmissions between second and third UEs (e.g., over sidelink resources). In one example, the first UE may transmit signaling indicating that retransmissions of a first message transmitted between a second and third UE and detected by the first UE may be reflected by the reconfigurable surface associated with the first UE. In another example, the first UE may receive a request from a second UE for signal enhancement using a reconfigurable surface, the request associated with a future transmission by the second UE to a third UE. In either case, the UE may determine to perform signal enhancement using a reconfigurable surface and may then reconfigure the reconfigurable surface for reflecting transmissions or retransmissions from the second UE to the third UE.

Abstract: Methods, apparatuses, and computer-readable medium for directional security are provided. An example method may include receiving, from a wireless device, a configuration for a set of shared keys. The example method may further include receiving, from a second UE, at least one message or signal including a location of the second UE, the received at least one message or signal being associated with an angle of arrival. The example method may further include configuring a key from the set of shared keys based on at least one of the received configuration, the location of the second UE, the AoA of the received at least one message or signal, or a location of the first UE. The example method may further include generating one or more ranging signals based on the configured key, the one or more ranging signals being directionally secure based on the location of the second UE.

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.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may identify a conflict between sidelink messages in one or more sidelink resources of a set of sidelink resources reserved for communications by a second UE. In response to identifying the conflict, the first UE may measure a system load of a sidelink channel for the sidelink messages and may determine a threshold system load of the sidelink channel based on one or more priorities associated with the conflicting sidelink messages. If the system load satisfies the threshold system load, the first UE may transmit a message that indicates the conflict. Additionally, or alternatively, the first UE may transmit the conflict indication using a resource determined based on whether one or more of the conflicting sidelink messages are a broadcast sidelink message or a groupcast sidelink message.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques support communication between one or more network entities and user equipment (UEs) via configurable intelligent surfaces. A first UE may transmit, to a second UE associated with a set of configurable intelligent surfaces, first information that indicates a tracking period and a data period that the second UE is to use to manage the configurable intelligent surfaces. The second UE may adjust the configurable intelligent surfaces for the communications between the first UE and network entities during the tracking period and the data period. The second UE may adjust the configurable intelligent surfaces based on measurement reports generated by the first UE based on communication during the tracking and data periods.
