Claim 0:
1. A method of operating a user equipment in a radio access network, wherein the method comprises:
receiving tracking reference signaling (TRS) in a TRS pattern, the TRS being received based on a coordination indication indicating operation of an LTE radio access network in coexistence with a New Radio (NR) radio access network for which the TRS pattern was transmitted, the coordination indication further indicating a reference signaling pattern for the LTE radio access network, the reference signaling pattern pertaining to a symbol time interval overlapping in part and coinciding in time with the symbol in which TRS is transmitted;
the TRS pattern represents a distribution of subcarriers for carrying TRS over a range of subcarriers shifted relative to a reference subcarrier corresponding to a central frequency subcarrier of a Long Term Evolution (LTE) carrier; and
the TRS pattern being shifted to be arranged above the reference subcarrier in frequency space, or is shifted to be arranged below the reference subcarrier in frequency space.
