Methods, apparatuses and systems related to enabling csi-based near field spot beams

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

• receive a first message comprising first information indicating a configuration of a set of precoders, a set of correction factors, association between each precoder of the set of precoders with at least one correction factor from the set of correction factors, and at least one reference signal (RS);
• receive, from a transmission reception point (TRP), at least one reference signal;
• determine a first precoder from the set of precoders based on at least one measurement on the at least one RS;
• determine, from the set of correction factors, a subset of correction factors associated with the first precoder;
• determine a correction factor from the subset of correction factors;
• determine a second precoder based on the first precoder and the determined correction factor;
• and
• transmit, to the TRP, a second message comprising second information indicating the second precoder.
