Abstract: Efficient opportunistic communications in integrated access and backhaul (IAB) frameworks are provided allowing scheduling nodes and scheduled nodes to communicate within an allocated set of resources based on a different configuration than for non-opportunistic communications using a different set of resources. An additional set of available resources may be allocated for coordinated communications between a parent IAB-node and the child IAB-node. Resources within this available set are associated with a first configuration, and when prior coordination exists, the parent IAB-node and child IAB-node may communicate based on this first configuration over this available set of resources. However, when prior coordination does not exist, the parent IAB-node and child IAB-node may opportunistically communicate over the allocated set of resources based on a second configuration different than the first configuration. Using different configurations, power may be conserved and resources managed more efficiently in opportunistic communications where unsuccessful transmissions may be more likely.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive information identifying a resource as a flexibly assigned resource, wherein the flexibly assigned resource is usable for an uplink or a downlink. The network node may resolve the resource based at least in part on a direction of one or more other resources preceding or succeeding the resource. Numerous other aspects are described.

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 TAB node in the TAB network is satisfied, based at least in part on at least one of: a change of a donor distributed unit associated with the TAB node, a central entity change associated with the TAB node, or an establishment, release, or modification of a route including the TAB node; and provide, to the TAB node, updated transport network layer information, based at least in part on the trigger condition being satisfied. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a radio unit (RU) may transmit, to a controller of the RU, a message including an ordered list of coordinates corresponding to a plurality of antenna elements in an antenna array of the RU. The RU may receive, from the controller, an indication of one or more low-level endpoints associated with one or more activated antenna elements of the plurality of antenna elements. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a child node in a wireless multi-hop network may receive a cost parameter from a neighbor node in the wireless multi-hop network, wherein the cost parameter indicates a cost, due to an operating mode of the neighbor node, of selecting the neighbor node as a target node for a handover procedure, a cell selection procedure, or a cell reselection procedure. The child node may perform the handover procedure, the cell selection procedure, or the cell reselection procedure based at least in part on the cost parameter. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node may receive a first indication of an energy-saving configuration for traffic routing associated with a traffic path between the first wireless node and a second wireless node. The first wireless node may transmit a second indication of the energy-saving configuration for traffic routing to the second wireless node. The first wireless node may communicate, with the second wireless node on the traffic path, in accordance with the energy-saving configuration. Numerous other aspects are described.

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: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for channel sensing with self-interference awareness for unlicensed band. A node may transmit, via a first entity of the node, at least one signal during a LBT procedure of a second entity of the node. The at least one signal may include a signal energy. The LBT procedure may be associated with a total measured interference from all detected energy sources. The node may determine a self-interference at the second entity of the node based on the signal energy of the at least one signal transmitted via the first entity of the node and calculate an interference from at least one other source based on a difference between the total measured interference from all detected energy sources and the self-interference determined based on the signal energy of the at least one signal.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for UL LBT status reporting. A scheduled node (e.g., a UE) may sense a status of each LBT channel in a set of one or more LBT channels. The set of one or more LBT channels may include at least one of one or more first LBT channels associated with a scheduling grant or one or more second LBT channels unassociated with the scheduling grant. The scheduled node may transmit, to a scheduling node (e.g., a base station), a LBT status report indicative of the status of each LBT channel in the set of one or more LBT channels. The scheduling node may schedule, via a second scheduling grant, a second set of one or more LBT channels based on the status of each LBT channel indicated in the LBT status report.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a control node may receive, from a wireless node, a status report of an unlicensed band associated with an unlicensed channel access of the wireless node, wherein the status report indicates listen-before-talk (LBT) failures during the unlicensed channel access of the wireless node. The control node may transmit, to the wireless node, an updated configuration for unlicensed channel access based at least in part on the status report of the unlicensed band. Numerous other aspects are described.
