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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first node may transmit a grant for a communication associated with a scheduling gap, wherein the scheduling gap is imposed with a minimum value over a set of resources, and communicate with a second node based at least in part on the grant. Numerous other aspects are provided.

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 communicate back with the COT initiating IAB node. The sharing of the COT with the parent IAB node and/or child IAB node may also include a sharing of the same COT between a distributed unit and a mobile terminal of the COT-initiating IAB node.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node may receive, from a second wireless node, a round-trip time timing advance indicator, wherein the round-trip time timing advance indicator is different from a timing advance indicator used for an uplink transmission timing advance message. In some aspects, the first wireless node may synchronize a timing configuration of the first wireless node to at least one of the second wireless node or a third wireless node based at least in part on the round-trip time timing advance indicator. 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) central unit may receive, for a first TAB node, at least one of a first indication of a first capability to provide a cell-specific component of a time difference between a distributed unit transmission of a signal from the first IAB node and a reception of the signal at a child node of the first TAB node (T_delta) or a second indication of a second capability to synchronize with a parent node of the first IAB node based on a received T_delta. The central unit may determine the first capability and the second capability of the first IAB node based on at least one of the first indication or the second indication. The central unit may determine a location of the first IAB node within a network topology based on the first capability and the second capability.

Abstract: A first apparatus may determine that a DU function of a child IAB node is to transition between a first set of resources associated with an MT function of the child IAB node and a second set of resources associated with the DU function. The first apparatus may further configure a guard period associated with the transition time based on the first set of resources and based on the second set resources. A second apparatus determine to transition between a first set of resources associated with an MT function of the second apparatus and a second set of resources associated with a DU function of the second apparatus at a transition time. The second apparatus may further transmit, to a parent IAB apparatus, information requesting a guard period associated with the transition time based on the transition between the first set of resources and the second set resources.

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.
