摘要： To address the problem of inter-cell interference, the present invention proposes a method for inter-cell interference coordination and a device thereof. In one embodiment of the present invention, there is provided a method of coordinating radio resource in a base station of wireless communication network, comprising the steps of: S1 determining whether a UE is of interference risk; if the UE is of interference risk, then S2 determining key interference source base station(s) of the UE; S3, scheduling radio resource in collaboration with the key interference source base station(s), so that the key interference source base station(s) idle(s) the radio resource assigned to the UE by the base station. With the method and device provided in the present invention, effective avoidance of inter-cell interference may be achieved, and every cell may fully reuse resource to accomplish reuse gain, while UE backward compatibility may also be supported.

摘要： The invention proposes a method of selecting an access base station in a user equipment of a wireless communication network, and the method generally includes the steps of: the user equipment selecting, among at least one base station, a small power base station preferably to perform an access, wherein a signal of each of the at least one base station covers the user equipment. Also the invention proposes a selecting access apparatus for selecting an access base station corresponding to the method. In an application scenario of the heterogeneous network including both small power base stations and macro base stations, the invention enables balanced usage of access resources in the heterogonous network while avoiding interference resulting from the preferable access to a macro base station with larger transmission power to thereby improve the overall performance of the heterogonous network and particularly a heterogonous network involving a hot zone.

摘要： A relay method and device, wherein the control signal and the data signal which are in the same subframe are directly sent to a lower level device respectively by an upper level device and a relay function device. In one example, the relay function device transmits data signal using subscriber special reference signal to make the lower level device estimate an access channel correctly; in another example, the relay function device carries out precoding of the data signal correlative with the access channel so as to cancel the influence of the access channel, thereby make the lower level device receive data signal correctly. Retransmission control signaling is sent to the lower level device in each subframe by the upper level device to ensure the fixed sequential relationship of feedback retransmission.
