Embodiment Construction

[0023] figure 1 What is shown is a chain connection structure for multiple remote radio frequency subsystems before the present invention as mentioned above.

[0024] figure 2 What is shown is a structural form of the ring connection method between the indoor unit of the wireless communication base station and the remote radio frequency transceiver of the present invention. The main body of this base station is an indoor base station device 100, and its specific composition can be referred to the previously existing "radio remote" method (application number 200510001653.2). There are two pairs (4) of interface units in the interface circuit 210 at the base station end, which are used to connect with the first bidirectional transmission line 221 and the second transmission medium 22m respectively. Multiple (n) remote radio frequency transceivers 201, 202, 203, 204, ..., 20n, which are only connected in series, are respectively connected through a bidirectional ring connectio...

Abstract

The invention relates to a ring-shape connection method between wireless communication base station signal-receiving-transmitting machines. While the wireless base station provided with base-band digital signal processing unit connects with one of remote radio frequency signal-receiving-transmitting machines by a first bi-directional transmission medium, a second bi-directional transmission medium connects with the other remote radio frequency signal-receiving-transmitting machine in ring-shape connection state. The on-state and off-state of the second transmission medium transmission channel is controlled by the wireless base station.

Description

technical field [0001] The invention relates to a system connection method of a wireless communication base station / transmitter and an interface structure of equipment compatible with the connection method. Background technique [0002] With the development of third-generation mobile communication systems including WCDMA and TD-SCDMA, due to the limitation of the radio wave propagation characteristics of its 2GHz working frequency band, it is inevitable to greatly increase the number of base stations and require them to achieve three-dimensional coverage, so its wireless base station equipment cannot Traditional design methods such as radio frequency transceivers designed by discrete components and chips with a small integration level, and low-loss radio frequency cables connected to receive and transmit antennas and radio frequency transceivers are used. With the increase in the number of transceivers, the characteristic differences between discrete components and the use o...
