Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for leveraging a resource management protocol under an integrated access and backhaul (IAB) framework for power savings. In some aspects, a first node (such as an IAB node) may receive resource management information from a second node (such as an IAB donor). The resource management information may indicate an unavailable type of resource management configuration for the first resource associated with the first node. The first node may schedule a power save mode during the first resource having the unavailable type of resource management configuration for power savings. The first resource may be a time domain resource, a frequency domain resource, or a spatial domain resource. In some aspects, the first node may restrict both non-exempt and exempt communications during the first resource when the first node is in the power save mode.

Abstract: Method and apparatus for null-forming at bidirectional smart repeaters. The apparatus transmits, to a repeater, a repeater configuration. The repeater configuration configures the repeater to beam shape at least one beam of the repeater to suppress at least one side lobe of the at least one beam. The apparatus communicates with the repeater based on the repeater configuration. The apparatus receives, from the repeater, information related to an existing codebook of the repeater and associated beam forming capabilities of the repeater. The apparatus receives, from the repeater, information related to a null-forming codebook configured at the repeater.

Abstract: A configuration for local coordination between the child node and parent node to enable SDM communication between the parent and child node, without input or interaction from the CU. The apparatus receives, from a CU, an indication including an allocation of resources. The apparatus determines a type of communication with a second node based on the allocation of resources. The apparatus communicates with the second node based on the determined type of communication and utilizing the allocated resources. The apparatus coordinates with a parent node to utilize the allocated resources in an SDM operation between the child node and the parent node.

Abstract: Methods, systems, and devices for wireless communications are described. Some networks, such as over-deployed integrated access and backhaul (IAB) networks operating in millimeter wave (mmW) bands, may experience high energy consumption if all nodes in the network are fully active at all times. Power utilization modes may mitigate energy consumption by allowing nodes to operate at varying levels of activity. A power utilization mode may include a fully active mode or may drop one or more functions that a fully active node may support, or may support less extensive configurations associated with one or more supported functions, as compared to the configurations associated with a fully active node. Nodes may request information regarding one or more nodes, request a change in power utilizations modes for itself, indicate another node should change modes, or may receive an indication to change modes.

Abstract: Methods, systems, and devices for wireless communications are described. The techniques described herein relate to a user equipment (UE) receiving, from a network entity while in a connected mode with the network entity, first control signaling indicating a coordination configuration. The coordination configuration indicates a subset of paging cycles from a set of paging cycles, the subset of paging cycles associated with an indication of a tracking reference signal (TRS) availability or an indication of a system information (SI) change message availability. The UE receives from the network entity via a paging cycle of the subset of paging cycles in accordance with the coordination configuration, second control signaling indicating an availability of a TRS in a TRS resource or an availability of an SI change message in the paging cycle. The UE receives from the network entity, the TRS or the SI change message based on the second control signaling.

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: Methods, systems, and devices for wireless communications are described that provide for timing adjustments that may be used in communications between wireless devices in a wireless communications system and signaling of such timing adjustments using physical layer signaling (e.g., layer 1 (L1) signaling). A first timing adjustment may be provided by a parent node to one or more associated child nodes that corresponds to a propagation delay between the parent node and its control node or a relay node through which the parent node communicates with a core network. In some cases, the physical layer signaling used to transmit the first timing adjustment may be a reference signal transmission, a downlink control information transmission, or any combination thereof.

Abstract: A method, a computer-readable medium, and an apparatus are provided. The apparatus may be an IAB node. The apparatus may receive communication from one or more of a parent IAB node or a child IAB node using a first frequency carrier of a paired spectrum comprising the first frequency carrier and a second frequency carrier. The apparatus may transmit communication to the one or more of the parent IAB node or the child IAB node using the second frequency carrier in the paired spectrum. At least one of the first frequency carrier or the second frequency carrier in the paired spectrum carries both uplink and downlink communication.

Abstract: Certain aspects of the present disclosure provide techniques for channel access in an unlicensed spectrum. An example method of wireless communication by a user equipment includes receiving a resource grant indicating a plurality of resource candidates for an uplink signal. The method also includes sensing for energy, in response to the resource grant, over one or more of the resource candidates in a first sensing occasion before a transmission occasion of the uplink signal. The method further includes transmitting, during the transmission occasion, the uplink signal using a subset of the resource candidates selected based at least in part on energy sensed in the first sensing occasion.
