Abstract: Aspects presented herein relate to methods and devices for wireless communication including an apparatus, e.g., a node or a base station. In one aspect, the apparatus may receive, via a first set of resources, communication including at least one data packet, the first set of resources allocated for a reception entity of the node. The apparatus may also decode, at the reception entity, the at least one data packet during a decoding period, the decoding period including a decoding start time and a decoding completion time. Additionally, the apparatus may transmit, via a second set of resources, the communication including the at least one data packet to a next hop node, the second set of resources allocated for a forwarding entity of the node, at least one first resource overlapping with at least one second resource.

Abstract: Aspects of the present disclosure provide techniques for packet delay budget (PDB) coordination between two integrated access and backhaul (IAB) nodes for a radio link control (RLC) channel in an IAB network. An IAB node may dynamically adjust its configured one-hop RLC channel PDB based on channel conditions or buffer loading associated with the IAB node. The IAB node may then indicate bonus PDB at a next-hop node or request additional PDB from the next-hop node.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an integrated access and backhaul (IAB) node may receive, from a first IAB donor centralized unit (CU) via a first parent distributed unit (DU), a first indication to establish a first connection with a second parent DU associated with a second IAB donor CU. The IAB node may establish the first connection with the second parent DU. The IAB node may establish a second connection with the first IAB donor CU via the second parent DU, the first connection and the second connection forming a target path between the IAB node and the first IAB donor CU. Numerous other aspects are provided.

Abstract: Aspects relate to establishing a signaling connection between a radio access network (RAN) node and a first scheduling entity. The RAN node may communicate in a dual connectivity (DC) mode of operation with the first scheduling entity (e.g., a secondary gNB) using a first radio access technology (RAT) and with a second scheduling entity (e.g., a master eNB) using a second RAT. The RAN node and the first scheduling entity may support sending information for a first signaling connection between the RAN node and the first scheduling entity over a second signaling connection through the second scheduling entity (e.g., when the second signaling connection is more reliable than the first signaling connection). To establish the second signaling connection, the RAN node and the first scheduling entity may signal support for the second signaling connection and exchange Internet Protocol information for the second signaling connection.

Abstract: An integrated access and backhaul (IAB) apparatus receives, from a child IAB node, a signal identifying a set of transition instances for the child IAB node, including a transition time for each transition instance, and provides guard symbols for a first transition instance of the set of transition instances at the transition time for the first transition instance.

Abstract: A relay supporting multiple relay modes is provided. The relay transmits capability information to a base station, the capability information indicating support for a first relay mode and a second relay mode. The relay determines a mode of operation, either on its own or based on an indication of a mode of operation from the base station, wherein the mode of operation comprises the first relay mode or the second relay mode. The relay communicates with at least one of the base station or another wireless device based at least in part on the determined mode of operation.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a child node of a parent node in an integrated access backhaul (IAB) network may determine communication information that includes one or more of a schedule or a configuration for a communication to be transmitted by the child node. The child node may be an IAB node, and the parent node may be an IAB donor or an intervening IAB node between the IAB node and an IAB donor. The child node may transmit the communication information to the parent node via a wireless backhaul link between the child node and the parent node. Numerous other aspects are provided.

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 configuration for transmission of an uplink reference signal for a handover procedure; transmit the uplink reference signal according to the configuration; and receive a handover command or monitor for a downlink reference signal for the handover procedure based at least in part on transmitting the uplink reference signal. Numerous other aspects are provided.

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: Disclosed are techniques for communication. In an aspect, a first network node receives, from a second network node, a request for location information for a user equipment (UE) served by the first network node, and transmits, to the second network node, a location information report for the UE, the location information report including at least an identifier of a sub-cell with which the UE is associated.
