Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive a system information block (SIB) including configuration information associated with configuring operation of a plurality of repeaters, wherein repeaters in the plurality of repeaters are configured to receive signals from first wireless communication devices and forward the signals to second wireless communication devices. The wireless communication device may communicate in a set of resources based at least in part on the configuration information included in the SIB. Numerous other aspects are provided.

Abstract: Aspects presented herein may enable an IAB node to modify a resource allocation or change one or more parameters related to the resource allocation when the IAB node detects that the resource allocation overlaps with guard symbols or another resource allocation. In one aspect, an IAB node determines that a first channel allocation will be punctured based on an overlap of the first channel allocation with at least one of a guard symbol or a second channel allocation. The IAB node uses, for the first channel allocation or the second channel allocation, one or more of a modified parameter or a modified grant in response to determining that the first channel allocation will be punctured.

Abstract: An integrated access and backhaul (IAB) node may transition between use of a mobile termination (MT) function at the wireless device and use of a distributed unit (DU) function. The IAB node may schedule communication using the DU function of the wireless device based on whether one or more guard symbols are provided for an allocation from a parent node for the MT function.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus synchronization configuration in different operation modes using communications systems operating according to new radio (NR) technologies. For example, a method for wireless communications by a base station (BS) may include determining an operation mode of the BS, determining a transmission configuration of at least one of a one or more synchronization channels or a one or more synchronization signals based on the operation mode, and transmitting the one or more synchronization channels or the one or more synchronization signals based on the determined transmission configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may identify one or more parameters indicating a mobility of a served node relative to a serving node. The wireless node may classify the served node within a category, among a plurality of categories, based at least in part on the one or more parameters. In some aspects, the plurality of categories may include at least a first category for served nodes that have a low mobility relative to the serving node and a second category for served nodes that have a high mobility relative to the serving node. Numerous other aspects are provided.

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.
