Methods, devices and systems for reporting frequency offset

A wireless communication device, comprising:

• at least one processor configured to:
• receive, via a transceiver from a wireless communication node, at least a first resource configuration to configure a pair of reference signals (RSs) to the wireless communication device for reporting of frequency offsets of the pair of RSs;
• perform measurement of the frequency offsets of the pair of RSs, the pair of RSs comprising a first reference signal (RS) and a second RS;
• and
• send, via the transceiver to the wireless communication node according to the at least a first resource configuration, at least one report of the frequency offsets.
