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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device (WCD) may receive, from a second WCD, transmission configuration indicator (TCI) state information that defines a set of TCI state configurations for a full duplex operation, wherein TCI state configurations of the set of TCI state configurations are associated with respective receive beams and respective transmit beams. The WCD may transmit, to the second WCD, an indication of one or more candidate TCI states, associated with the set of TCI state configurations, for selection by the second WCD for communications using the full duplex operation. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described that support sidelink cancellation for out of coverage user equipment. Described techniques provide for signaling of cancellation indications to a user equipment (UE) or a group of UEs to refrain from performing sidelink communications on a set of resources. A base station may transmit a cancellation indication to one or more sidelink UEs via an access link that indicates that an allocation of one or more resources for sidelink communications has been canceled. A first UE may receive the cancellation indication from the base station via the access link and transmit a sidelink communication to one or more other UEs that indicates the canceled resource allocation. Based on the sidelink communication of the cancellation indication from the first UE, the one or more other UEs may refrain from transmitting using the canceled resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive, from a base station (BS), an indication of an inter-beam phase factor tracking reference signal configuration for inter-beam phase factor tracking, wherein at least one of the wireless communication device or the BS performs multi-beam combining over at least two static directions or beams from one or more antenna panels. The wireless communication device may perform one or more measurements of an inter-beam phase factor tracking reference signal based at least in part on the inter-beam phase factor tracking reference signal configuration. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In one aspect, a first user equipment (UE) may transmit an indication of non-preferred resources to a second UE and an indication of an amount of transmit power reduction for the second UE to observe for a sidelink transmission on the non-preferred resources. In another aspect, a first UE may transmit an indication of an amount of transmit power reduction for a second UE to observe for a sidelink transmission on conflicting resources (e.g., resources reserved by the second UE and a third UE). Because the second UE may transmit on the non-preferred resources or the conflicting resources with reduced power (e.g., rather than suppressing transmissions on the non-preferred resources or the conflicting resources), the utilization of the non-preferred resources or the conflicting resources may be improved.

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: A wireless device, such as a user equipment (UE), may receive first scheduling information with first resources for periodic transmissions with a first beam based on a half-duplex mode. The wireless device may receive second scheduling information for second resources associated with a second beam that is incompatible with the first beam for full duplex communication including downlink reception and uplink transmission that overlaps in time. The wireless device may adjust communication in response to the first beam being incompatible with the second beam for the full duplex communication.
