1. A terminal for a Radio Access Network, the terminal comprising:
radio circuitry; and
control circuitry operatively coupled to the radio circuitry,
wherein the radio circuitry and control circuitry are configured to transmit based on a first frequency division multiple access (FDMA) technology and to transmit based on a second FDMA technology, the second FDMA technology differing from the first FDMA technology, and wherein the radio circuitry and control circuitry are configured to transmit reference signaling having a comb structure for transmission based on either the first FDMA technology or the second FDMA technology.
