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.

First claim

configuring, by the main control module, information of a cell needing load sharing from the master board to the slave board;
modifying, by the main control module, a configuration parameter of the cell according to a baseband processing capability of the LTE base station, or configuring, by the main control module, user information to each of the master board and the slave board according to a load balance;
allocating, by the L2 scheduling module according to the load balance, a plurality of uplink user devices needing to be processed at a current TTI (transmission time interval) to the master board and the slave board;
sending, by the L2 scheduling module, an uplink scheduling indication to each of the master board and the slave board;
processing, by the master board, physical uplink control channels (PUCCHs) and physical uplink shared channels (PUSCHs) of a portion of the plurality of uplink user devices; and
