Abstract: This disclosure provides systems, methods and apparatuses for transmission of synchronization signal blocks (SSBs) using adjusted transmit powers. In one aspect, a power offset may be configured for one or more sets of SSBs. The power offset may be configured to be applied for a set of SSBs based on a duplexing mode of one or more of a transmitter wireless node (that transmits an SSB) or a receiver wireless node (that receives the SSB). The duplexing mode may be based on whether the transmitter receiver node or the wireless receiver node is operating in a full-duplex mode or may be based on a resource configuration associated with a resource used to transmit the SSB. Some techniques and apparatuses described herein also provide signaling to support the transmission of SSBs using adjusted transmit powers, and techniques for receiving and processing SSBs that use adjusted transmit powers.

Abstract: Aspects described herein relate to identifying an aggressor node that transmits interfering signals that cause interference to signals received at the node, communicating a configuration for applying a phase shift to the interfering signals for forwarding to the node from a reflecting node with the phase shift applied, and communicating, from the reflecting node, the interfering signals with the phase shift applied to at least partially cancel the interference to the signals received at the node.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive mobility state information associated with an integrated access backhaul (IAB) node. The mobility state information may include information associated with at least one of: a level of mobility of the IAB node, or a change in mobility of the IAB node. The wireless communication device may perform an operation based at least in part on the mobility state information associated with the IAB node. In some aspects, a wireless communication device may determine that mobility state information associated with an IAB node is to be transmitted, and may transmit the mobility state information associated with the IAB node based at least in part on the determination. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide techniques for inter-donor topology discovery in an Integrated Access and Backhaul (IAB) network during migration of an IAB-node. A method that may be performed by a first IAB-donor includes establishing a first signaling connection with an IAB-node, receiving an indication that the IAB-node has a second signaling connection with a second IAB-donor, and in response to receiving the indication: transferring, to the second IAB-donor, information related to the IAB-node, re-establishing traffic between the first IAB-donor and the IAB-node via a topology of the second IAB-donor, or any combination thereof.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a base station may determine a transmit power to be used by a downstream node or an amplification gain to be used by the downstream node when relaying or repeating messages to a target node. The base station may transmit, to the downstream node, a message intended for the target node, the message having an indicated transmit power, wherein the message intended for the target node is transmitted by the base station using an actual transmit power. In some aspects, the indicated transmit power is the transmit power to be used by the downstream node, so that when the message intended for the target node is repeated by the downstream node, the indicated transmit power of the repeated message matches the actual transmit power of the repeated message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may select a communication configuration for use with a repeater wireless node that is using a power detection procedure; and transmit a signal, to the repeater wireless node and to be forwarded by the repeater wireless node to a target wireless node, in accordance with the communication configuration selected for use with the repeater wireless node that is using the power detection procedure. Numerous other aspects are described.

Abstract: Techniques for partial configuration of an autonomously smart repeater may allow a control entity (e.g., base station, UE, or cloud software/algorithm) to configure the autonomously smart repeater and thereby improve end-to-end performance for some communications. In an example, a relay device may receive, from a first entity, an indication for reconfiguring a parameter corresponding to an autonomous reconfiguration procedure of the relay device. The relay device may configure a setting of the autonomous reconfiguration procedure according to the parameter. The relay device may forward a signal between a first wireless device and a second wireless device based on the configuring.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an integrated access and backhaul (IAB) node may receive at least part of a resource pattern of a child IAB node associated with the IAB node. The resource pattern may indicate one or more configurations of one or more resources of the child IAB node. The IAB node may communicate with the child IAB node based on the at least part of the resource pattern. Numerous other aspects are provided.

Abstract: An integrated access and backhaul (IAB) donor central unit (CU) may transmit, to an IAB-node, a plurality of messages for a child of the IAB-node, the plurality of messages including a first message being associated with a first condition, and a second message being associated with a second condition, and transmit an indication instructing the IAB to forward, to the child, the first message if a first condition is met or the second message if a second condition is met. The IAB-node may receive, from the IAB-donor-CU, the indication, determine that one condition among the first condition and the second condition has occurred, forward one of the first message or the second message to the child based on the occurrence of the one condition, and discard the other of the first message or the second message.

Abstract: A UE may receive, from a base station, scheduling information for a first DL transmission associated with half-duplex mode and a second DL transmission associated with full duplex mode, determine priorities of the first and second DL transmissions, and monitoring for a higher priority DL transmission among the first and second DL transmissions. The UE may transmit a first UL transmission associated with a half-duplex mode and a second UL transmission associated with a full duplex mode, and the base station may determine priorities of the first and second UL transmissions. The priority may be determined by the duplex mode or the content of the first and second DL transmissions and the first and second UL transmissions.
