Document Type and Number:
WIPO Patent Application WO/2015/085839
Kind Code:
A1
Abstract:
The present invention relates to the technical field of communications. Disclosed in an embodiment of the present invention are a data communication method, system and device. A first base station covering a serving cell of a user equipment determines for the UE the resource scheduling information used for data communication in the serving cell, and sends the resource scheduling information to a second base station, the second base station being a base station in a cooperative cell of the UE, so that the second base station prohibits other UEs from occupying resources corresponding to the resource scheduling information; when receiving information of scheduling not allowed returned by the second base station, the first station will send uplink authorization to the UE to allow the UE to perform data communication over the resource corresponding to the above resource scheduling information in the serving cell, thus avoiding conflict of resource occupation by UEs between base stations, achieving interference coordination between base stations, and preventing interference of the data communication of UEs in a cooperative cell to the data communication of UEs in a cell.
