The present invention provides a method of allocating channel processing resources of radio links one by one in a centralized base station, comprising the step of: allocating channel resources with a radio link as a unit, according to resource allocation requirements of a wireless communication system in which said centralized base station is located, so as to respectively allocate uplink and downlink wireless signals of corresponding cells in said centralized base station to at least one channel processing unit in the centralized base station, so that the allocated channel processing units perform service channel processing of a part of users of the corresponding cells, respectively. The present invention further provides a centralized base station for implementing the above method. The method and the centralized base station allocate channel resources with a radio link as a unit and allows uplink and downlink wireless signals of one cell to be simultaneously allocated to at least one channel processing unit so as to respectively perform service channel processing of a part of users of the cell, thereby maximizing utilization of channel processing resources and realizing flexible allocation of channel processing resources.
