Methods, architectures, apparatuses and systems directed to wireless transmit/receive unit (WTRU) initiated active sensing

A wireless transmit/receive unit, WTRU, comprising circuitry, including a transmitter, a receiver, a processor and memory, configured to:

• receive first information from a network element of a wireless communications system, wherein:
• the first information indicates an activation of at least a first sensing configuration of a plurality of sensing configurations;
• the first sensing configuration comprises second information indicating a first resolution level;
• and
• the plurality of sensing configurations comprises at least a second sensing configuration comprising third information indicating a second resolution level, wherein the second resolution level is different from the first resolution level;
• transmit a first sensing signal according to the first sensing configuration;
• perform one or more measurements related to the first sensing signal;
• transmit fourth information to the network element based at least in part on the one or more measurements and the first resolution level, wherein the fourth information indicates a request for change in resolution level;
• and
• receive, from the network element, fifth information indicating the second sensing configuration.
