Abstract
The invention relates to a method of signal transmission between a host BTS and Remote Radio Unit(s), and the BTS communication system thereof. The transmission channel between the host BTS and the Remote Radio Unit(s) uses wideband transmission links or a network, the method includes the following steps of: performing the transmission over the transmission channel using a Synchronous Digital Hierarchy (SDH)/Optical Transmission Network (OTN), forming a digital wireless signal data stream and an in-band control signaling stream transmitted over the transmission channel into a Generic Framing Procedure (GFP) frame which is further mapped to a STM-N/OTM-n frame, thereby multiplexing the digital wireless signal data stream and the in-band control signaling stream to realize SDH/OTN-based transmission. As a result, the wireless signal can be effectively transmitted between the RRH and the host BTS without specific transmission network, and the management and maintenance operation required by the signal transmission and the networking cost can be reduced.
