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: Certain aspects of the present disclosure provide a method for wireless communications by a first user equipment (UE). The method generally includes receiving a first sidelink transmission from a second UE, determining resources for providing a feedback responsive to the first sidelink transmission, selecting one or multiple transmitter receiver points (TRPs), from a set of TRPs of the UE, for transmitting the feedback, based on one or more conditions, and transmitting the feedback on the determined resources using the selected TRPs.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for assisted mmW sidelink beam discovery in non-standalone mode. A UE may transmit, to an AN, a request to access one or more ADs. The request may be based on an absence of at least one BPL that has a threshold QoS for a DRB with a second UE. The UE may receive, from the AN based on the transmitted request, an authorization to access the one or more ADs, and exchange, via an SRB, beam training information with the second UE based on the authorization to access the one or more ADs for performing a beam training procedure via the one or more ADs.

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: A user equipment (UE) may sense a first transmission by a first sidelink UE and a second transmission by a second sidelink UE and send a conflict indication to at least one of the first or second sidelink UEs in response to identifying a collision between the first and second transmissions, or identifying a prospective collision based on a prospective use of respective first and second resources identified in the respective first and second transmissions. A collision or prospective collision may be detected by detecting a complete or partial overlap of the first and second transmissions or of the prospective first and second resources identified in the transmissions, or by determining that any portions of the first resource and the second resource prospectively occupy a slot common to the first and second resources, and the first sidelink UE and the second sidelink UE prospectively operate in a half-duplex mode.

Abstract: An apparatus (e.g., a third UE) may be configured to detect at least one SPS conflict in a set of REs between a first SL (e.g., an SPS-based) transmission associated with a first UE and a second SL transmission associated with a second UE. The third UE may further be configured to transmit, upon detecting the SPS conflict, an indication of the SPS conflict to at least one of the first and second UEs. A first UE may be configured to receive, from the third UE, the indication of the SPS conflict, the indication of the SPS conflict including information regarding a set of resources associated with the detected conflict. The first UE may be further configured to initiate a resource re-selection for the first SL transmission based on the received indication and to transmit the first SL transmission based on the resource re-selection.
