Abstract: This disclosure provides systems, methods, and devices for wireless communication that support techniques for operating repeaters based on sub-band power measurements. According to some aspects, sub-band-based power measurements may also allow a repeater to acquire other side information, e.g., time division duplex (TDD) downlink/uplink information or beam configuration information, more accurately. In aspects, a repeater determines one or more sub-band received-signal powers associated with one or more sub-bands of a bandwidth available for wireless communication, amplifies one or more signals received within at least one of the one or more sub-bands, and transmits the amplified one or more signals to at least one of a user equipment (UE) or a base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a central unit (CU) may transmit, to a first wireless node, an indication of a traffic flow configuration associated with a traffic flow on a traffic path that includes the first wireless node and a second wireless node. The CU may transmit, to the first wireless node, energy-saving scheduling information indicating one or more periods in which to use the traffic flow configuration for the traffic flow on the traffic path. Numerous other aspects are described.

Abstract: Aspects of the present disclosure provide techniques of allocating time resources (or slots) based on a flexible pattern that allows allocation of a set of non-continuous time slots resources in an integrated access and backhaul (IAB) system. In one example, the aggregation pattern may be indicated via a single downlink control information (DCI) message that carries explicit information regarding non-continuous time slot allocation. Features of the present disclosure may also include techniques to allow for early termination of transmission between the first node and the second node when the receiver (e.g., second node) successfully receives the data channel before the end of aggregated transmission. In such situation, the first node and the second node may cease transmission after reception of an acknowledgement (ACK) message that may allow the second node to utilize the subsequent time slots for communication with its own children on the next hop (e.g., third node).

Abstract: Wireless communications systems and methods related to sharing channel occupancy time (COT) for a channel in an unlicensed 5G spectrum in an integrated access backhaul (IAB) network are provided. In some aspects, an IAB node of the IAB network may perform a channel access procedure to acquire the COT and share the COT with a parent IAB node and/or a child IAB node for the parent IAB node and/or child IAB node to share, or use the COT for communication, with a third IAB node different from the COT-initiating IAB node.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a central entity may determine a set of schedulable resources for a plurality of links associated with a plurality of nodes of a multi-link network; and may provide scheduling information to the plurality of nodes to schedule communication on the plurality of links based at least in part on determining the set of schedulable resources. In some aspects, a node of a network may determine an extended slot format indicator for the node based at least in part on a received extended slot format indicator of a parent node of the node and a received null adjust request from a child node of the node; may provide the determined extended slot format indicator to the child node; and may provide the received null adjust request to the parent node. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support network controlled repeater operation at new radio—unlicensed (NRU) bands. The network controlled repeater operations include receipt of a scheduling message from a serving base station that identifies an amplify and forward (AF) window and an offset prior to a beginning of the AF window. The relay node performs a listen before talk (LBT) procedure on a shared communication channel within the offset. In response to the result of the LBT, the relay node either refrains from AF operations within the AF window in response to failure of the LBT procedure or performs the AF operations on all received signals during the AF window in response to success of the LBT procedure. Other aspects and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may identify a scaling factor associated with determining a periodicity of backhaul physical random access channel (PRACH) resources. The wireless communication device may determine, based at least in part on the scaling factor, the periodicity of the backhaul PRACH resources. The periodicity of the backhaul PRACH resources may be extended as compared to a periodicity of access PRACH resources. Numerous other aspects are provided.

Abstract: Aspects described herein relate to resource allocation in an integrated access and backhaul (IAB) system. In an example, the aspects include receiving, by a wireless node, an indication of not-available (NA) resources of a parent node, the NA resources corresponding to a first set of one or more resources configured at the parent node as being unavailable for uplink and downlink communications between the parent node and the wireless node, wherein the indication of NA resources of the parent node comprises an invalid time division duplex (TDD)-uplink-downlink configuration; and refraining, by the wireless node, from communicating with the parent node within the NA resources based on the indication of NA resources of the parent node.

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.
