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: An apparatus acquires random access information for at least one of a donor node serving the node or a neighbor cell of the node and determines one or more random access parameters for a device to perform a random procedure with the node. The one or more random access parameters are based on the acquired random access information. The apparatus may be an IAB node.

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.

Abstract: Disclosed is a method for wireless communication. A first node determines that a beam failure recovery procedure, an initial beam pair establishment procedure, or a beam refinement procedure is completed. Based on the determination, the first node performs a sensing procedure that comprises receiving sidelink control information (SCI) from a third node. Based on the sensing procedure, the first node selects a sidelink grant for a sidelink transmission to a second node and transmits the sidelink transmission to the second node based on the selected sidelink grant.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for performing a common channel sensing procedure for transmissions via a mobile termination (MT) role or via a distributed unit (DU) role of an integrated access and backhaul (IAB) node, or both. In one aspect, the IAB node may obtain channel access for transmissions via the MT role or the DU role, or both, using the same channel sensing procedure. The IAB node may select a timing of a sensing slot for the common channel sensing procedure in accordance with a capability of the IAB node and a timing of the transmissions. The IAB node may initiate a channel occupancy time (COT) for the transmissions via the MT role or the DU role, or both, as a result of determining that a measured energy detection (ED) value satisfies an ED threshold.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for updating a slot format during full duplex (FD) operation. An example method by a user equipment (UE) generally includes receiving signaling for the UE to operate on at least one active bandwidth part (BWP) and participating in FD communications in the at least one active BWP on at least some symbols, based on a first slot format associated with the at least one active BWP.

Abstract: Certain aspects of the present disclosure provide techniques for autonomous reference signal transmission configuration. Certain aspects provide a method of receiving a configuration message from the base station, wherein the configuration message comprises an indication of a set of candidate resources for transmitting the reference signal. Certain aspects provide a method of detecting a future downlink transmission from the base station, and other aspects provide a method of transmitting, in response to detecting the future downlink transmission, the reference signal utilizing a first resource of the set of candidate resources prior to receiving the future downlink transmission via a second resource in the set of candidate resources.
