Abstract: In some aspects, a base station may transmit a configuration that indicates a resource set to be used by a millimeter wave repeater for beam management, wherein the resource set includes a first set of resources to be used by the millimeter wave repeater to receive one or more reference signals from a first node and a second set of resources to be used by the millimeter wave repeater to relay the one or more reference signals to a second node. The base station may identify a first beam pair and a second beam pair based at least in part on the one or more reference signals received and/or relayed in accordance with the configuration, wherein the first beam pair is between the millimeter wave repeater and the first node and the second beam pair is between the millimeter wave repeater and the second node. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described that provide for mesh connectivity between integrated access and backhaul (IAB) nodes. A first node of an IAB network may determine a routing address for a second node, and communications may be transmitted to the second node based on the routing address to allow for coordination between the first and second nodes. The first node may detect a discovery signal of a second node, and may determine to communicate with the second node based on the discovery signal. The first node may obtain the routing address based on one or more of transmitting a request for the routing address to a third node, establishing a sidelink connection with the second node to obtain the routing address, receiving a mapping between routing addresses and cell IDs that are transmitted in discovery signals, or any combinations thereof.

Abstract: Methods, systems, and devices for wireless communications are described that support resource utilization based event triggering. A wireless node in a wireless communications system may establish a connection with a core network via a path that includes one or more relay nodes. The wireless node may determine that a network load associated with one or more paths between the wireless node and the core network has changed, or that a difference between two or more network loads of different paths has changed. Based on such a determination, the wireless node may transmit a report to the network. In some cases, the network may receive the report from the wireless node, and may initiate a path change based on the report.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a random access occasion may overlap in time with a synchronization signal block resource, where the random access occasion and the synchronization signal block resource have a same index. In some such examples, a base station may transmit, to a user equipment (UE), an indicator of a mapping of the random access occasion to an uplink beam that is associated with a synchronization signal block resource with a different index than the random access occasion. The UE may transmit, to the base station, a random access preamble over the random access occasion using the uplink beam.

Abstract: Aspects of the present disclosure provide techniques for addressing scenarios where the minimum transmit power supported by an Integrated Access and Backhaul (IAB) node is above a minimum value specified by a standard. In some cases, the IAB node may signal information regarding its power configuration so a network entity of the IAB may take it into account (e.g., when allocating or scheduling resources). The power configuration may include an indication of the minimum transmit power supported by the IAB node and/or an indication of a guard band that may help the IAB node control adjacent channel leakage.

Abstract: Methods, apparatuses, and computer-readable mediums for wireless communication are disclosed by the present disclosure. In an example, the present disclosure includes receiving, at a second device, a Random Access Channel (RACH) preamble from a first device, the RACH preamble initiates an access procedure between the first device and the second device; selecting, by the second device, a transmission resource associated with a second RACH message based on the RACH preamble; and transmitting, by the second device, the second RACH message on the selected transmission resource to the first device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a central unit (CU) may determine a set of resources that is unavailable for use by a distributed unit (DU) of the CU, the set of resources including one or more resources. The CU may transmit information identifying the set of resources that is unavailable for use by the DU to cause an inferior node of the DU to refrain from using the set of resources that is unavailable for use by the DU. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described that provide for synchronization signal (SS) burst set patterns in which SSs and broadcast channel transmissions may be transmitted (e.g., in time). A base station may identify a SS burst set pattern indicating positions (e.g., time locations) for SS block transmissions, for example, in bandwidth restricted communication systems. The SS burst set pattern may be determined based on numerology or subcarrier spacing associated with SSs and non-SSs. The base station may transmit an indication of the SS burst set pattern to a wireless device. The wireless device may receive the indication of the SS burst set pattern and determine one or more time locations of SSs (e.g., primary synchronization signal (PSS), secondary synchronization signal (SSS), physical broadcast channel (PBCH) of a SS block). The wireless device may then monitor the identified positions for SSs.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may select a random access channel (RACH) occasion (RO) based on one or more channel quality thresholds, such as reference signal received power (RSRP) thresholds. A base station may determine a set of RO types for receiving RACH transmissions. The base station may determine a channel quality threshold for each RO type. The base station may broadcast a configuration indicating the RO types and the associated channel quality thresholds. The UE may receive the configuration and measure a channel quality between the UE and the base station. Based on the measured channel quality, the UE may determine which RO types are available based on the indicated channel quality thresholds, and select an RO for transmitting a RACH preamble to establish a connection with the base station based on the available RO types.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may receive a measurement configuration, from a second wireless device, to support full-duplex operation using a shared resource. The first wireless device may transmit, via the shared resource, a first signal via a first transmission beam using a first antenna array of the first wireless device. The first wireless device may monitor, in accordance with the measurement configuration, the shared resource using a first receive beam via a second antenna array of the first wireless device. The first wireless device may then transmit a measurement report to a second wireless device based on the monitoring. The second wireless device may transmit, to the first wireless device, a duplexing configuration configuring the full-duplex operation of the first wireless device based on the measurement report.
