Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a central entity in an integrated access and backhaul (IAB) network may determine that a trigger condition for updating transport network layer information of an IAB node in the IAB network is satisfied, based at least in part on at least one of: a change of a donor distributed unit associated with the IAB node, a central entity change associated with the IAB node, or an establishment, release, or modification of a route including the IAB node; and provide, to the IAB node, updated transport network layer information, based at least in part on the trigger condition being satisfied. Numerous other aspects are described.

Abstract: Wireless communications systems and methods are provided for a base station (BS) to configure initial sweeping with one or more repeaters. For example, a BS may determine a sweeping configuration based on any combination of measurement reports from the repeater and/or received information on the capabilities or category of the repeater. Capabilities can include codebook information, repeater's architecture, beam switching latency, synchronization level, and/or the like. Measurement reports may be transmitted by and/or between a repeater to a BS following an initial connection setup between a repeater and a BS. Other aspects and features are also claimed and described.

Abstract: An apparatus may configure a first set of resources associated with first control information for a relay device. The apparatus may configure a second set of resources associated with at least one of data or second control information for at least one UE, and the second set of resources may at least partially overlap with the first set of resources. The apparatus may transmit information indicating the first set of resources and the second set of resources to the relay device. Further, the apparatus may communicate, with the relay device, the first control information on the first set of resources and the at least one of data or second control information on the second set of resources, and the relay device may be configured to relay the at least one of data or second control information between the apparatus and the at least one UE.

Abstract: Disclosed are techniques for non-line-of-sight (NLOS) target detection. In an aspect, a source vehicle receives, from a roadside unit (RSU), a notification that the RSU is capable of repeating radar signals transmitted by the source vehicle in NLOS directions from the source vehicle, receives, from an active radar repeater associated with the RSU, radar signals for a radar beam sweep in at least one NLOS direction from the source vehicle, receives an angle of each beam of the radar beam sweep, and performs target object detection based on the radar signals for the at least one NLOS direction and the angle of each beam of the radar beam sweep. Example architectures for the active radar repeater are also disclosed.

Abstract: Certain aspects of the present disclosure provide techniques for managing beam failure recovery operations. A method that may be performed by a user equipment (UE) generally includes determining at least one reference signal (RS) associated with a first cell that is configured without a control-resource set (CORESET). The method also includes monitoring the at least one RS associated with the first cell. The method further includes detecting a beam failure on the first cell based on the monitoring of the at least one RS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify multiple candidate sets of physical sidelink feedback channel (PSFCH) transmissions that include hybrid automatic repeat request (HARQ) feedback for sidelink communications received from one or more peer UEs. The UE may select, from one or more of the multiple candidate sets that satisfy a PSFCH transmit power constraint, at least one candidate set that has a highest value for a utility parameter among utility parameters associated with each of the one or more candidate sets that satisfy a PSFCH transmit power constraint. The UE may transmit, on a PSFCH, the plurality of PSFCH transmissions included in the at least one candidate set in a HARQ feedback occasion. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first node may transmit, to a second node, a first message providing a first indication of integrated access and backhaul (IAB) capability. The first node may receive, from the second node and in response to the first message, a second message providing a second indication of IAB capability. The first node may establish an IAB capable connection with the second node based at least in part on the first message and the second message. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive, via a mobile termination (MT) and from a central unit (CU) of a donor network node, a first message that includes first information associated with a token. The network node may transmit, via a distributed unit (DU) and to the CU of the donor network node, a second message that includes second information associated with the token, to thereby indicate collocation of the MT and the DU. Numerous other aspects are provided.
