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.

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: 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: Aspects of the present disclosure provide techniques for addressing scenarios where the minimum transmit power supported by a wireless node (e.g., an Integrated Access and Backhaul (IAB) node) is above a minimum value specified by a standard. In some cases, the node may signal information regarding its power configuration so a network entity of the may take it into account (e.g., when allocating or scheduling resources). The power configuration may include an indication of the minimum transmit power supported by the node and/or an indication of a guard band that may help the IAB control adjacent channel leakage.

Abstract: Aspects of the present disclosure provide techniques for beam and cell selection based on power configuration of a wireless node (e.g., an Integrated Access and Backhaul (IAB) node). In some cases, the node monitors synchronization signal block (SSB) transmissions from one or more network entities, and selects a beam or cell based on the monitoring and one or more metrics designed to limit potential interference caused by uplink transmissions from the first node.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a parent node may determine that a set of resources is not available for the parent node for communication with a child node of the parent node. The parent node may provide an availability indicator to the child node based at least in part on determining that the set of resources is not available for the parent node for communication with the child node. The availability indicator may indicate the set of resources as available for the child node. Numerous other aspects are provided.

Abstract: The present disclosure relates to methods and devices for wireless communication at a wireless device or integrated access and backhaul (IAB) node. In one aspect, the wireless device may determine a frequency synchronization accuracy for the wireless device. The wireless device may also transmit an indication of the determined frequency synchronization accuracy for the wireless device. Additionally, the wireless device may determine an absolute frequency based on a combination of measurements from at least one synchronization source and a frequency of the wireless device, where the frequency synchronization accuracy is based on the absolute frequency.

Abstract: Certain aspects of the present disclosure provide systems and techniques for full-duplex communication. A first system is characterized by techniques for communicating in full-duplex utilizing the Butler matrix beamformer for generating a spatial beam to be used for both uplink and downlink signaling, wherein the signaling utilizes the same time and frequency resources. A second system is characterized by techniques for communicating in full-duplex utilizing the Butler matrix beamformer to generate two spatial beams, one to be used for downlink and one to be used for uplink signaling, wherein the signaling utilizes the same time and frequency resources. Accordingly, the systems and techniques described herein are directed to low complexity, multi-user full-duplex communications.
