Abstract: Certain aspects of the present disclosure provide techniques for configuring timing advances for uplink communications resources. A method for wireless communications by a user equipment includes receiving, from a base station, signaling that configures a first timing advance and a second timing advance. The first timing advance is configured to be used by the user equipment when transmitting an uplink communication in a half-duplex resource, and the second timing advance is configured to be used by the user equipment when transmitting an uplink communication in a full-duplex resource. The method may further include transmitting, to the base station, a first uplink communication within a first resource using one of the first timing advance or the second timing advance based on whether the first resource comprises a half-duplex resource or a full duplex resource.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform, in a full duplex communication mode, a channel measurement (CM) procedure associated with a self-interference measurement (SIM) procedure to determine a downlink signal to self-interference plus noise ratio associated with a downlink (DL) and uplink (UL) (DL/UL) beam pair of the UE; receive, from a base station, uplink interference information associated with a UL beam of the DL/UL beam pair of the UE, wherein the uplink interference information indicates at least one of: a final DL/UL beam pair selected by the base station; and transmit a measurement report based at least in part on the CM procedure and the SIM procedure, wherein the measurement report is based at least in part on the downlink signal to self-interference plus noise ratio. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods, and apparatuses for retransmission of a communication by a relay node based on a failure of a target node to receive the communication. In some aspects, the relay node may determine that the second wireless node has failed to receive the second communication, or an upstream wireless node (such as a distributed unit) may determine that the target node has failed to receive the communication. The relay node may retransmit the communication based on such a determination. In some aspects, the relay node may buffer the communication or information used to generate the communication, and may retransmit the buffered communication. In some aspects, a configuration for the retransmission may be modified based on a capability of the relay node or another concern.

Abstract: Aspects of the present disclosure provide techniques for interference measurements based on a priority value in a network (e.g., an Integrated Access and Backhaul (IAB) network). Certain aspects provide a method for wireless communications. The method generally includes determining, at a first wireless node, a priority value associated with the first wireless node configured to serve one or more child nodes, determining occurrence of interference to communications of the first wireless node and/or a second wireless node, and taking one or more actions in response to the determination of the interference based on the priority value.

Abstract: Certain aspects of the present disclosure provide techniques for reporting of a beam correspondence state. Certain aspects provide a method for wireless communication by a first wireless device. The method includes, based on detecting the occurrence of a triggering event, determining one or more beam correspondence states for one or more beams or portions of beams used by the first wireless device for communication. The method further includes transmitting one or more indications of the one or more beam correspondence states to a second wireless device, wherein the one or more indications of the one or more beam correspondence states indicate whether the first wireless device has the capability of beam correspondence between the one or more beams and corresponding one or more transmit or receive beams used by the first wireless device for communication.

Abstract: Aspects of the present disclosure provide techniques for handover in an Integrated Access and Backhaul (IAB) network or other type of network. One example method which may be performed by a source base station (BS) includes: determining to migrate a child node from a first logical IAB-distributed unit (DU) of an IAB-node to a second logical IAB-DU of the IAB-node, wherein the first logical IAB-DU is associated with the source BS, and wherein the second logical IAB-DU is associated with a target BS; sending, to the target BS, context information of the child node served by the first logical IAB-DU in response to the determination; and indicating, to the target BS, a traffic mapping configuration at the IAB-node associated with the context information and a backhaul connection of the IAB-node.
