Abstract: Various aspects include methods for receiver (RX) beam sweep configuration of a millimeter wave (MMW) repeater during random access channel (RACH) procedures. Various embodiments may include determining two or more different RX beam sweep configurations for one or more RACH occurrences (ROs) associated with a synchronization signal block (SSB), generating a RACH configuration message indicating the two or more different RX beam sweep configurations for the one or more ROs, and sending the RACH configuration message to an MMW repeater. Various embodiments may also include receiving a RACH configuration message indicating two or more different RX beam sweep configurations for one or more ROs associated with an SSB, and controlling one or more RX antennas of the MMW repeater to perform RX beam sweeping during the one or more ROs according to the RACH configuration message to receive a RACH message 1 from a computing device.

Abstract: Aspects of the present disclosure provide techniques for interference coordination between wireless nodes (e.g., nodes of an Integrated Access and Backhaul (TAB) network). The techniques generally include determining, by a first wireless node, resources for sending an indication of interference coordination to a second wireless node, and sending the indication to the second wireless node using the determined resources, as part of an interference coordination procedure.

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: The present disclosure provides techniques for addressing switching times of Integrated Access and Backhaul (IAB) child nodes. For example, a parent IAB node may determine a switching time for the child IAB node to switch from transmitting on a backhaul/uplink to a parent node (with transmit power control) to transmitting on an access/downlink to a user equipment (UE) or other child IAB node. The parent IAB node may then configure the IAB child node according to the determined switching time (e.g., by scheduling the IAB child node accordingly or setting one or more timing advance parameters).

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.

Abstract: Aspects provide for autonomous adjustment of the uplink and downlink transmission timing in wireless communication networks. A scheduled entity (e.g., a user equipment (UE) or child integrated access backhaul (IAB) node) may observe a change in the downlink reception timing of downlink signals transmitted from a scheduling entity (e.g., a base station or parent IAB node). The scheduled entity may then autonomously adjust its uplink transmission timing to compensate for the change in downlink reception timing. In addition, the scheduled entity may further maintain the same downlink transmission timing irrespective of the change in downlink reception timing.
