Abstract: A wireless communication method and a wireless communication device. The wireless communication method is used in a coordinated multi-point communication system, and includes: recognizing an edge user equipment; determining the presence of interference to an enhanced physical downlink control channel (ePDCCH) of the edge user equipment; and in response to the determination of the presence of the interference, determining different interference coordination manners according to different scenarios, so as to control the transmission of the ePDCCH or a physical downlink shared channel (PDSCH) of a neighbor cell related to the interference.

Abstract: A communication apparatus, communication system and communication method. The related communication apparatus is used for aggregating, at a base station side, communication resources at different frequencies and/or different transmission time, wherein a scheduling resource among the aggregated communication resources is used for transmitting control information about the scheduling resource and scheduled resources. The communication apparatus includes: a grouping unit configured to divide the communication resources into groups based on characteristics of the communication resources, wherein the same group of the communication resource is indicated by the same piece of control information; and a sending unit configured to send the control information to a corresponding communication terminal side by the scheduling resource. The communication apparatus, communication system and communication method improve communication performance.
