DMRS for MMW RAN

A transmitting node for a communication network, the transmitting node including radio circuitry configured to:

• transmit 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.

A method of operating a receiving node in a millimeter-wave communication network, the method comprising:

• receiving 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.
