Abstract

A method for implementing a baseband resource pool in an LTE base station is provided. The LTE base station includes a main control module, a master board a slave board. The master board and the slave board each include a baseband processing module. The main control module configures information of a cell needing load sharing on the master board to the slave board, and configures user information in the cell to each of the master board and the slave board, or configures the user information to each of the master board and the slave board according to load balance. The master board and the slave board each perform load sharing processing on an SRS signal of a user. The slave board including the baseband processing module is added, thereby improving the baseband processing capability of the LTE base station.
