1. A method for transmitting a plurality of antenna signals between a main Base Transceiver Station (BTS) and one or more Remote Radio Units (RRUs), wherein the transmit channel between the main BTS and the one or more RRUs communicates using a wideband transmission link or a network, and at least one said RRU communicates the plurality of antenna signals with the main BTS over the transmit channels by using a plurality of antennas, the method comprising the steps of:

  • transmitting over the transmit channel using a Synchronous Digital Hierarchy (SDH)/Optical Transmission Network (OTN);

    multiplexing the plurality of antenna signals over the transmit channel using time division multiplex; and

    forming the antenna signal stream multiplexed and an in-band control signaling stream together into a Generic Framing Procedure (GFP) frame, and further mapping the GFP frame to a STM-N/OTM-n frame, thereby multiplexing the plurality of antenna signals and the in-band control signaling stream to realize the SDH/OTN-based transmission.
