Abstract

The invention relates to a frequency hopping method and a frequency hopping device for inter-cell interference elimination in first network equipment. The method comprises the step of sending frequency hopping information to second network equipment, wherein the frequency hopping information comprises resource allocation information, and the resource allocation information comprises at least one of power allocation information, dispatching allocation information and beam forming allocation information. The frequency hopping information further comprises frequency hopping configuration information, wherein the frequency hopping configuration information comprises frequency hopping initial sub-frame information, initial resource allocation information associated with a frequency hopping initial sub-frame and frequency hopping parameters. The invention further provides a method and a device for avoiding interference fluctuation caused by frequency hopping in the first network equipment. The method comprises the step of selecting or reconstructing channel state information corresponding to the current source so as to dispatch user equipment based on at least one piece of channel state information from the user equipment. The scheme provided by the invention realizes random frequency hopping among sub-frames, and the stability of inter-cell interference elimination information in frequency hopping is ensured at the same time.

Description

technical field [0001] The present invention generally relates to the field of communications, and in particular to a frequency hopping method and device for eliminating interference between cells in the field of communications. Background technique [0002] In traditional static or semi-static resource allocation, such as static or semi-static inter-cell interference cancellation / enhanced inter-cell interference cancellation, the resource allocation will change after a few minutes, hours or days, and it may also be in the network Fixed when deployed. In this way, the preferred scheduling area for the offended user equipment (for example, the interfered user equipment) may be limited to some fixed subcarriers for a long time, thus the frequency selectivity gain will be greatly reduced. In order to maximize the frequency selectivity gain of the victimized user equipment, the frequency selectivity gain can be realized by frequency hopping. However, frequency hopping of resou...
