1. A method of operating a transmitting node in a communication network, the method comprising:
transmitting communication signaling in a transmission timing structure, the communication signaling comprising:
leading reference signaling in a leading time interval at a beginning of the transmission timing structure;
trailing reference signaling in a trailing time interval at an end of the timing structure; and
intermediate reference signaling in an intermediate time interval between the leading time interval and the trailing time interval; and
the leading reference signaling starting with a first reference signaling time-domain sequence, and the trailing reference signaling ending with the first reference time-domain signaling sequence, the leading reference signaling configured to include an embedded suffix reference signal time domain sequence and an embedded prefix reference signal time domain sequence, the embedded suffix reference signal time domain sequence being in a reverse order of the embedded prefix reference signal time domain sequence.
