    Abstract: Methods, systems, and devices for wireless communications are described in which UEs may communicate with satellites and base stations or gateways in a non-terrestrial network (NTN). Due to the large distances between transmitting devices and receiving devices in a NTN, timing adjustments to account for propagation delay communications links via a satellite may include a propagation delay between a UE and a satellite, a propagation delay between a base station and a satellite, as well as a variation in the propagation delays due to movement of the satellite. In accordance with various techniques discussed herein, a UE may account for variation in propagation delay, in addition to determined propagation delay, when determining an uplink timing for uplink communications via a satellite.

    Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for measuring, filtering, and reporting cross-link interference (CLI) in cases where not all aggressor user equipments (UEs) are transmitting signals that can be measured by a victim UE. A UE may obtain a set of CLI measurements by performing CLI measurements during a set of CLI measurement occasions. The UE may determine a first subset of the set of CLI measurements that satisfy a CLI measurement threshold and a second subset of the set of CLI measurements that do not satisfy the CLI measurement threshold. The UE may apply a filter to the first subset of the set of CLI measurements, and suppress the filter for the second subset of the set of CLI measurements, to obtain a filtered CLI measurement value. The UE may transmit the filtered CLI measurement value to a base station.
