Abstract

A system and method for random access measurement indications are disclosed herein. In one embodiment, a method performed by a first communication node includes: obtaining measurement results from a plurality of signals; determining a matching measurement result of the measurement results that corresponds to a matching signal of the plurality of signals, wherein the matching measurement result best matches with a criteria; selecting determining random access channel (RACH) resources based on the matching signal; sending a first message using the RACH resources; and receiving a second message based on the matching signal.
