Disclosed are an uplink data transmission method, apparatus, and system. The method comprises: a centralized processing node delivering control information that comprises address information of a serving evolved remote radio unit (ERRU) and a transmission mode of an ERRU to an ERRU in a coordinated multi-point transmission (COMP) set, other ERRUs in the COMP set than the serving ERRU being non serving ERRUs; and receiving compressed uplink COMP frequency domain data sent according to the transmission mode by the serving ERRU, the compressed uplink COMP frequency domain data being data compressed from original uplink COMP frequency domain data sent by the serving ERRU to a non serving ERRU and original uplink COMP frequency domain data of the serving ERRU, and receiving original uplink COMP frequency domain data sent according to the transmission mode by at least one ERRU. In embodiments of the present invention, a compression gain can be obtained by compressing data, thereby reducing uplink transmission traffic between an ERRU in the COMP set and the centralized processing node. |
