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). One example method generally includes determining, based on a priority level associated with each of a first wireless node, a second wireless node, or both, at least one configuration for communicating one or more synchronization signal blocks (SSBs) between the first wireless node and the second wireless node, each of the first wireless node and the second wireless node being configured to serve one or more child nodes, wherein the at least one configuration comprises information enabling the first wireless node or the second wireless node to manage interference to communications. In some aspects, the method may also include transmitting the at least one configuration to at least one of the first wireless node or the second wireless node.

The present application relates to devices and components including apparatus, systems, and methods of scheduling transmission of synchronization signal blocks (SSBs) at a subcarrier spacing (SCS) of 480 or 960 kHz.

In an aspect, a communications node (e.g., TRP or UE) obtains (e.g., measures) timing group delays associated with different positioning procedures to determine time drift information, and reports the time drift information to an external entity for position estimation. In some designs, positioning procedures may comprise round trip time (RTT) measurements or uplink or downlink Difference Of Arrival (TDOA) measurements. In some designs, the time drift information indicates a drift rate function.
