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: 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 relate to signal measurements. A first apparatus (e.g., a distributed unit) may measure a signal associated with a user equipment that does not have a connection with the first apparatus. The first apparatus may output measurement information based on the signal measurement to a second apparatus (e.g., a central unit). In response, the second apparatus may output a message based on the measurement information. In some examples, the second apparatus may determine whether to activate or deactivate a cell associated with the first apparatus based on the measurement information, and send a corresponding message to the first apparatus. In some examples, the second apparatus may forward some or all of the measurement information to a third apparatus (e.g., another distributed unit or a base station) for use in interference mitigation operations and/or power coordination operations.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a network entity within a first coverage area associated with a first wireless cell. The UE may receive a system information (SI) update indication that indicates a modification of the first coverage area to a second coverage area. The SI update indication may also include one or more thresholds that the UE may use to determine whether the UE is to receive an updated SI message associated with the modification of the first coverage area to the second coverage area, or whether the UE is to skip receiving the updated SI message associated with the modification of the first coverage area to the second coverage area. The UE then determines whether to receive the updated SI message based on the one or more thresholds.

Abstract: Methods, systems, and devices for wireless communications are described. An integrated access and backhaul (IAB) node may have a radio resource control (RRC) connection with a first central unit of a first network node. The IAB node may receive an indication that the IAB node is to establish an IAB node-to-central unit connection (e.g., a F1 detour connection) with a second central unit of a second network node via the RRC connection between the IAB node and the first network node. The indication may be associated with a handover between the first network node to the second network node, where the first network node may the source node and the second network node may be the target node, or vice versa. The IAB node may communicate, with the second network node, via the IAB node-to-central unit connection using the RRC connection between the IAB node and the first network node.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a source node may forward a first message between a user equipment (UE) and a core node via a distributed node, wherein the first message is a non-access stratum message. The source node may transmit, to a target node, a second message associated with a migration of the distributed node from the source node to the target node, wherein the second message identifies the forwarding of the first message. 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: This disclosure provides systems, methods, and devices for wireless communication that support network controlled repeater operation at new radio—unlicensed (NRU) bands. The network controlled repeater operations include receipt of a scheduling message from a serving base station that identifies an amplify and forward (AF) window and an offset prior to a beginning of the AF window. The relay node performs a listen before talk (LBT) procedure on a shared communication channel within the offset. In response to the result of the LBT, the relay node either refrains from AF operations within the AF window in response to failure of the LBT procedure or performs the AF operations on all received signals during the AF window in response to success of the LBT procedure. Other aspects and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a repeater network node may obtain a measurement gap configuration that indicates a measurement gap to be used by the repeater network node for performing a measurement. The repeater network node may receive a downlink signal from a transmitter network node. The repeater network node may transmit the downlink signal, to a user equipment (UE), based at least in part on the downlink signal being received during the measurement gap. Numerous other aspects are described.

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.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an integrated access and backhaul (IAB)-donor central unit (CU) may trigger connectivity between a distributed unit (DU) of a first network node and the IAB-donor CU, wherein the first network node comprises an IAB-node. The IAB may instantiate connectivity between a mobile terminal (MT) of the first network node and the IAB-donor CU after instantiation of the connectivity between the DU of the first network node and the IAB-donor CU. The IAB may transmit a communication to a second network node via the first network node. Numerous other aspects are described.

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: 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: Methods, systems, and devices for wireless communications are described. Aspects of the disclosure relate to enhanced load reporting between network entities (e.g., provided by a distributed unit (DU) to a centralized unit (CU) or by a CU to another CU). In some examples, the CU may provide one or more triggering events which may be used by the DU (or a second CU) to trigger the provisioning of a load report to the CU. Accordingly, the DU (or second CU) may be able to initiate a load report without relying on periodic reporting criteria. In some examples, the DU may initiate a load report to the CU without being configured with triggering events. In some examples, a DU may report measurements made associated with a communications load involving communications with both a parent network entity (e.g., a CU) and at least one child network entity (e.g., a user equipment).

Abstract: Aspects are provided which allow a network entity to receive an uplink transmission from a UE in UE DTX or cell DRX based on dynamic activation or deactivation of a DTX configuration or an associated uplink transmission configuration with respect to DTX. In some examples, the UE receives a DTX configuration associated with a UE transmission configuration and indicating an active time duration for a UE transmission associated with the UE transmission configuration. The UE also receives the uplink transmission configuration, such as an SR configuration, and a semi-static or dynamic indication of an active status of the DTX configuration or the uplink transmission configuration with respect to the DTX configuration. Afterwards, the UE transmits the UE transmission during the active time duration indicated in the DTX configuration based on the active status. As a result, less uplink transmission monitoring may result at the base station, providing network energy savings.

Abstract: Aspects of the present disclosure provide mechanisms for transmitting discovery signals to enable discovery of a cell. Synchronization signal blocks (SSBs) carrying the cell identifier of the cell may then be transmitted either on-demand or with a higher periodicity than discovery signals. The discovery signals and SSBs may be transmitted within a same bandwidth part and on at least overlapping sets of frequency resources.

A method includes receiving, from a first user equipment, a first uplink trigger message in a receive direction while in a first energy mode, wherein while in the first energy mode, the network entity is configured to: deactivate any synchronization signal blocks (SSBs) in the receive direction; monitor for uplink trigger messages during one or more configured uplink trigger occasions; and transitioning from the first energy mode to a second energy mode based at least in part on the first uplink trigger message, wherein while in the second energy mode, the network entity is configured to: activate one or more SSBs in the receive direction; and monitor for uplink trigger messages during the one or more configured uplink trigger occasions.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network entity, an indication of a required minimum value for a time offset associated with a communication with the network entity, wherein the required minimum value for the time offset is associated with communicating with the network entity via an assisting node. The UE may receive, from the network entity, an indication of an offset value for the time offset based at least in part on the required minimum value for the time offset. The UE may communicate with the network entity via the assisting node in accordance with the offset value. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described that provide for cell access procedures based on multiple types of discovery signals that may be transmitted by network entities operating in an energy saving (ES) mode. A user equipment (UE) may establish wireless connectivity via a first network entity and receive a discovery signal from a second network entity that contains less information than a synchronization signal block (SSB) for use in a cell access procedure. The UE may transmit, based at least in part on one or more conditions associated with the discovery signal being satisfied, a trigger signal to the ES-mode second network entity to transmit a SSB for use in the cell access procedure. The UE may monitor for the SSB based at least in part on the trigger signal, and perform the cell access procedure based at least in part on the SSB.

Abstract: Methods, systems, and devices for wireless communications are described. A first network entity (e.g., a distributed unit (DU)) may receive, from a second network entity (e.g., a centralized unit (CU)), a control message indicating a common discontinuous reception (C-DRX) configuration associated with a set of user equipments (UEs) communicatively coupled to the first network entity, where the C-DRX configuration indicates a time period including an active duration and an inactive duration. The first network entity may then communicate with two or more of the set of UEs in accordance with the indicated C-DRX configuration during the active duration of the time period of the C-DRX configuration.
