Methods, architectures, apparatuses and systems for near-field and/or far-field beam selection

A wireless transmit/receive unit, WTRU, comprising at least one processor configured to:

• measure received power of a received first downlink, DL, reference signal, RS, received from a network;
• upon determination that a value based on the measured received power satisfies at least one first criterion:
• determine a value range to which the value belongs;
• determine a set of second DL RS associated with the determined value range;
• measure the determined set of second DL RS to obtain a corresponding set of first measurement results;
• select a DL RS from the set of second DL RS based on the set of first measurement results;
• and
• transmit, to the network, information indicative of at least one of the selected DL RS and the corresponding first measurement result.

• select a first DL RS from the first set based on the measured received powers;
• determine a second set of DL RS that is associated with the first DL RS;
• measure the determined second set of DL RS to obtain respective measurement results;
• determine a RS based on the measurement results;
• and
• transmit information indicative at least one of the determined RS and the respective measurement results.
