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 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 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 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: An access node may monitor for uplink and downlink resource release indications signaled by a parent access node and a child access node prior to scheduling a released resource. In some cases (e.g., when the child node is capable of half-duplex communications), the parent access node may determine to release a resource, and the child access node may determine to release a hard resource (e.g., a child node controlled resource). Receiving uplink and downlink resource release indications may enable the access node to schedule communication with the child node via a soft resource (e.g., a parent node controlled resource). Other aspects of the described techniques are directed to feedback support for a slot format indicator (SFI). The feedback from the access node may accept or reject the SFI based on an impact the SFI has on scheduling via a child link established with a child node of the access node.

Abstract: Aspects relate to technologies and techniques for migrating a radio access network (RAN) node associated with a first donor node in a communications network. The first donor node may receive, via a first communications interface, such as an F1-C or resource control (RRC) interface, cell configuration data associated with one or more cells of the RAN node activated by the first donor node. The first donor node may process the cell configuration data and transit the cell configuration data, using a second communications interface, such as an Xn or X2 interface, to a second donor node for use in migrating the RAN node from the first donor node to the second donor node.

Numerous other aspects are provided.

Abstract: Techniques for using simultaneous connectivity for mobility of integrated access and backhaul nodes may include an IAB node establishing a first connection with a first parent node (e.g., second IAB node) associated with a first IAB donor device (e.g., first base station) and establishing a second connection with a second parent node (third IAB node), wherein the second connection is simultaneous with the first connection. The IAB node may also switch the first connection from the first parent node to the second parent node. In doing so, the IAB node may have dual connectivity with the second parent node, where one connection is a master connection and the other connection is a secondary connection.

Abstract: In a channel occupancy time (COT), a scheduling entity can transmit a first downlink (DL) transmission burst to a scheduled entity, and receive an uplink (UL) transmission burst from the scheduled entity. The scheduling entity can determine whether the scheduled entity performed a type 1 or type 2 channel access procedure for the UL transmission burst. A scheduled entity can use a first type of channel access procedure to initiate a first COT on a communication channel and request a network access node to perform a second type of channel access procedure in a next DL transmission burst. A network access node can receive a message from a scheduled entity, wherein the message comprises a control indication requesting the network access node to perform a first type of channel access procedure in a next DL transmission burst.

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. For example, a first wireless node (e.g., an integrated access and backhaul (IAB) node) may receive, from a parent base station, system information that is indicative of two random access procedure configurations. The first random access procedure configuration may be for a two-step random access procedure and the second random access procedure configuration may be different from the first random access procedure configuration (for example, an IAB-specific, a user equipment (UE)-specific, or a four-step random access procedure). The first wireless node may determine to use the first random access procedure configuration (e.g., for establishing a wireless backhaul connection with the parent base station) and may perform the two-step random access procedure with the parent base station accordingly.
