Abstract
A multi-mode base station and a method for sending/receiving signals thereof are provided. In the base station, each base-band single-board is connected to a corresponding radio frequency (RF) unit through a multi-mode exchange bus, and the base-band single-boards of different modes are intermixed by using the compatibility of the exchange bus with in-phase/quadrature (IQ) data of various modes. Synchronization information, such as frame numbers required by various modes, forms a synchronization burst through multiplexed framing. Meanwhile, by using the same system clock, the synchronization burst and system clock are transmitted to the base-band single-boards of various modes through a set of synchronization clock buses. The main control and transmission functions are uniformly provided for each base-band single-board in the base station by a shared common module. The filling and synchronization of wireless IQ data of various modes are realized according to common-multiple relation mapping.

14. A method for sending signals of a multi-mode base station, comprising:
-
performing, by base-band single-boards of different modes, base-band processing on downstream data to generate in-phase/quadrature (IQ) data, and outputting the IQ data to an exchange bus; transmitting, by the exchange bus, the IQ data from base-band single-boards to a corresponding radio frequency (RF) unit in a manner compatible with each of a plurality of multi modes for RF processing; and sending, by the RF unit, the data downwards after RF processing; wherein the exchange bus is compatible with each of the multi modes in the following manner; carrying, by the exchange bus, in-phase/quadrature (IQ) data using a basic frame group as a unit, each basic frame group comprising N basic frames, and a period of each basic frame group being M times as long as a service data mode period; and filling, by a base-band single-board and RF unit, the IQ data of M service data mode periods in one basic frame group for transmission, wherein N and M are natural numbers. - View Dependent Claims (18)
