Abstract: Aspects relate to enhancing the provision of gaps at transitions between resources allocated for communication on access links and resources allocated for communication on backhaul links. In some examples, a child integrated access backhaul network (IAB) node may transmit a message to a parent IAB node requesting a number of guard symbols to provide a gap at transitions. In some examples, the parent IAB node may transmit the number of guard symbols provided at transitions to the child IAB node. The parent IAB node, child IAB node, and/or an IAB donor node central unit may further identify a subcarrier spacing associated with the number of guard symbols.

Abstract: Example aspects include a method, apparatus, and computer-readable medium for network-triggered reestablishment by a network node of a wireless communication network, comprising transmitting, to a user equipment (UE) in a connected state with a first central unit (CU), an indication to perform a radio resource control (RRC) reestablishment procedure with a second CU. The indication comprises a reestablishment cell identifier. The aspects further include performing the RRC reestablishment procedure with the UE to transfer the UE from the first CU to the second CU using the reestablishment cell identifier.

Abstract: Example implementations include a method, apparatus, and computer-readable medium of wireless communication for a network node to transport signaling used to coordinate management of a RAN for local traffic between a first node and a UE across a wireless connection. The network node may establish a first wireless signaling connection between a first node and a second node. The network node may encapsulate or decapsulate traffic associated with a second wireless signaling connection within the first wireless signaling connection. The second wireless signaling connection corresponds to a non-F1 interface of a control plane or user plane network function that terminates at the first node. For instance, the network node may be a consumer premises equipment (CPE) serving a UE, a base station wirelessly serving the CPE, or a core network node providing control for the UE.

Abstract: Aspects described herein relate to receiving, at a repeater and from a serving base station, one or more transmitted downlink beams, receiving, at the repeater and from a downstream node served by the serving base station, one or more transmitted uplink beams, and transmitting, to the serving base station, one or more parameters related to determining a channel quality metric using at least the one or more transmitted downlink beams and the one or more transmitted uplink beams.

Abstract: Aspects presented herein may enable a transmitting entity, such as a base station, to indicate to one or more receiving entities that SSBs of one or more cells (which may include the transmitting entity) are to be transmitted with modified configurations. The method may also enable the transmitting entity to transmit modified SSBs to enable network energy saving. In one aspect, a base station configures one or more cells of a plurality of cells with one or more modified SSBs associated with an ES mode. The base station transmits an indication of the one or more cells associated with a transmission of the one or more modified SSBs, the transmission of the one or more modified SSBs corresponding to an ES mode at the one or more cells, the one or more cells being associated with the base station or at least one other base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a parent node may configure first and second backhaul radio link control (RLC) channels based on requests received from a first integrated access and backhaul (IAB) donor central unit (CU) and a second IAB donor CU, respectively. The parent node may select first and second logical channel identifiers for the first and second backhaul RLC channels, the second logical channel identifier being different from the first logical channel identifier, and may provide the first and second logical channel identifiers to the first IAB donor CU and the second IAB donor CU, respectively. The parent node may receive a packet including either the first logical channel identifier or the second logical channel identifier, and process the packet based on which of the first and second logical channel identifiers is included in the packet. Other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described that provide for mesh connectivity between integrated access and backhaul (IAB) nodes. A first node of an IAB network may determine a routing address for a second node, and communications may be transmitted to the second node based on the routing address to allow for coordination between the first and second nodes. The first node may detect a discovery signal of a second node, and may determine to communicate with the second node based on the discovery signal. The first node may obtain the routing address based on one or more of transmitting a request for the routing address to a third node, establishing a sidelink connection with the second node to obtain the routing address, receiving a mapping between routing addresses and cell IDs that are transmitted in discovery signals, or any combinations thereof.

Abstract: Methods, systems, and devices for wireless communications are described that support delaying the application of reconfiguration messages. An integrated access and backhaul (IAB) node transmit or receive, along a first signaling path, a reconfiguration message indicating the first IAB node to postpone applying a reconfiguration message until a second signaling path becomes available. The first IAB node may send a reconfiguration complete message to a first IAB donor node along the first path and wait to perform a procedure with the first IAB donor node. When the second path becomes available, the first IAB node and the second IAB node may then perform the procedure. In some cases, delaying the reconfiguration may involve postponing the forwarding of messages received at the first IAB node.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for communicating, by a relay node, in a time division multiplexing (TDM) mode, with a parent node via a parent link configured between the relay node and the parent node and with a child node via a child link configured between the relay node and the child node, identifying a TDM alignment conflict between a first transmission scheduled for the parent link and a second transmission scheduled for the child link, and transmitting a conflict indication (e.g., a cancellation message or an interruption message) to the parent node or the child node.

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.
