Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a node, such as a node in an integrated access backhaul (IAB) deployment, may receive information identifying a timing advance value and a timing assistance value, wherein the timing assistance value is associated with a configuration parameter. The node may perform a downlink transmission to a child node of the node based at least in part on the timing advance value and the timing assistance value and in accordance with the configuration parameter. Numerous other aspects are provided.

Abstract: This disclosure generally relates to systems, devices, apparatuses, products, and methods for wireless communication. For example, a communication system may include a repeater having a first communication interface that receives a control message that indicates a measurement configuration for a second communication interface of the repeater that is different than the first communication interface. The repeater receives, via the second communication interface, a first signal at the repeater from a first device. The repeater also measures a power metric associated with the first signal based on the measurement configuration. In some implementations, a base station or another device (e.g., UE), may communicate with the repeater and take one or more actions based on the power metric measured by the repeater.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a central unit (CU) may determine a set of resources that is unavailable for use by a distributed unit (DU) of the CU, the set of resources including one or more resources. The CU may transmit information identifying the set of resources that is unavailable for use by the DU to cause an inferior node of the DU to refrain from using the set of resources that is unavailable for use by the DU. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may receive, via a first interface of a repeater, information associated with a second interface of the repeater. The base station may determine a configuration for the second interface of the repeater based at least in part on the information associated with the second interface, and may communicate the configuration for the second interface of the repeater via the first interface. In some aspects, a repeater may transmit, to a base station via a first interface, information associated with a second interface of the repeater. The repeater may receive, via the first interface, a configuration for the second interface, and may configure the second interface based at least in part on the configuration. Numerous other aspects are provided.

Abstract: Aspects described herein relate to determining, based on a received signal strength, a set of potential backhaul nodes for providing a backhaul link in an integrated access and backhaul (IAB) network, determining, based at least in part on additional information regarding the set of potential backhaul nodes, at least one backhaul node of the set of potential backhaul nodes to which to connect over the backhaul link in the IAB network, and indicating, to an access node, the at least one backhaul node for attempting connection over the backhaul link.

Abstract: Disclosed are techniques for determining a beam-specific timing advance for Round-Trip Time (RTT) estimation. In an aspect, a first node receives a plurality of beams transmitted by a second node on a wireless channel, selects a first beam from the plurality of beams for transmitting a timing response, determines a timing statistic, a timing difference, and a timing advance for the first beam, wherein the timing difference comprises a difference between the timing statistic and an earliest time of arrival of the plurality of beams, and wherein the timing advance comprises a multiple of the timing difference, and transmits the timing response for the first beam to the second node on the wireless channel, wherein the first node transmits the timing response after a time delay from the timing statistic of the first beam, wherein the time delay comprises a difference between a predetermined time delay and the timing advance.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node may receive, from a second wireless node, a first type of timing advance indicator, wherein the first type of timing advance indicator is associated with a first type of connection associated with a first group of wireless nodes, of a network, that includes the first wireless node and the second wireless node and is different from a second type of timing advance indicator used for a second type of connection associated with a second group of wireless nodes of the network. In some aspects, the first wireless node may synchronize a timing configuration of the first wireless node based at least in part on the first type of timing advance indicator. Numerous other aspects are provided.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may perform a slot reservation procedure to obtain a TxOP for communicating with a second UE. The slot reservation procedure may be performed in an earliest slot in the TxOP in which the first UE has data to send to the second UE. The apparatus may transmit the data to the second UE using at least one slot in the TxOP when the slot reservation procedure is successful. In certain aspects, all remaining slots in the TxOP may be reserved for the first UE when the slot reservation procedure is successful. The apparatus may refrain from performing a subsequent slot reservation procedure in another slot in the TxOP when the slot reservation procedure is unsuccessful unless an end of transmission signal is received during the TxOP.
