    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: An angular relationship determination method includes: obtaining, at an apparatus, a first phase difference indication corresponding to a first difference in phase between a first signal wirelessly received by a wireless signaling device from a transmitter and a second signal wirelessly received by the wireless signaling device from the transmitter; and determining, at the apparatus, a first angular relationship between the transmitter and the wireless signaling device based on the first phase difference indication, a first virtual focal point location corresponding to the first signal, and a second virtual focal point location corresponding to the second signal, the second virtual focal point location and the first virtual focal point location being different.
