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: Wireless communications systems and methods related to communicating in an integrated access backhaul (IAB) network are provided. A first wireless communication device receives synchronization information associated with one or more wireless communication of a multi-hop wireless network. The first wireless communication device determines a transmission timing adjustment for a second wireless communication device of the one or more wireless communication devices based on at least some of the synchronization information. The first wireless communication device transmits a message instructing the second wireless communication device to communicate with a third wireless communication device of the one or more wireless communication devices based on the transmission timing adjustment.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a distributed unit (DU) of an integrated access and backhaul (IAB) node may receive, from a centralized unit (CU) of an IAB donor, an indication of a mobility state of a child node of the DU. The DU may perform an admission control for the child node based at least in part on the mobility state of the child node. Numerous other aspects are described.

Abstract: A method, a computer-readable medium, and an apparatus are provided. The apparatus may be a repeater node. The apparatus may receive, at one or more first antennas of the node, a first signal via at least one first beam. The apparatus may measure, at one or more third antennas of the node, at least one of a power or a quality of at least one third beam. The at least one of the power or the quality of the at least one third beam may be measured at a same time as the first signal is received. The apparatus may forward, at one or more second antennas of the node, the first signal via at least one second beam.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first node of a wireless network may transmit, by a first distributed unit (DU) of the first node to a central unit (CU), a second DU of another node in the wireless network, a user equipment in the wireless network, or a child node of the first node, an indication of a suggested resource pattern for the DU. The first node may transmit or receive a communication in the wireless network based at least in part on a resource pattern that is received in connection with transmitting the indication. Numerous other aspects are described.

Abstract: An integrated access and backhaul (IAB) node receives, from a parent IAB node, a time difference parameter for over-the-air (OTA) synchronization in an IAB network. The IAB node adjusts transmission or reception of the IAB node based on the time difference parameter for one of multiple types of IAB node alignment.

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.
