Methods of hierarchical srs configuration and cross-link interference (cli) measurement over shared resources in subband non-overlapping full duplex (sbfd) systems

A wireless transmit/receive unit (WTRU) comprising:

• a memory and a processor, wherein the processor is configured to:
• receive configuration information, wherein the configuration information comprises an indication that the first WTRU is to measure one or more cross-link interference (CLI) measurements in time and frequency resources associated with a plurality of sounding reference signal (SRS) transmissions, wherein the CLI measurements are associated with a subband non-overlapping full duplex (SBFD) slot;
• perform a first set of one or more CLI measurements of the time and frequency resources;
• determine whether to perform a second set of one or more CLI measurements based on a comparison of the first set of one or more CLI measurements to a threshold;
• and
• send an indication of the first set of one or more CLI measurements.
