The present invention relates to a frequency hopping method and device for inter-cell interference elimination in a first network device. The method includes sending frequency hopping information to a second network device, where the frequency hopping information includes resource allocation information, and the resource allocation information includes at least one of power allocation information, scheduling allocation information, and beamforming allocation information. The frequency hopping information further includes frequency hopping configuration information, and the frequency hopping configuration information includes frequency hopping initial subframe information, initial resource allocation information associated with the frequency hopping initial subframe, and frequency hopping parameters. The present invention also proposes a method and device for avoiding interference fluctuations caused by frequency hopping in the first network equipment, which includes selecting or reconstructing the channel corresponding to the current resource based on at least one piece of channel state information from the user equipment channel state information to schedule the user equipment. The scheme of the present invention realizes random frequency hopping between subframes, and at the same time ensures the stability of inter-cell interference cancellation information during frequency hopping.
Description
Technical field [0001] The present invention generally relates to the field of communications, and more particularly to frequency hopping methods and apparatus for inter-inter-inter-interval interference elimination in communication. Background technique [0002] In traditional static or semi-static resource allocation, such as static or semi-static interval interference cancellation / enhanced version of interval interference cancellation, resource allocation will change in a few minutes, hours or days, or may be in the network It is fixed when deployed. Thus, the preferred scheduling area for the infringement user equipment (e.g., interference user equipment) may be limited to some fixed subcarriers, thereby, and the frequency selective gain will greatly decrease. In order to maximize the frequency selective gain of the user equipment, the frequency selective gain can be achieved by frequency hopping. However, resource allocation of frequency hopping can lead to problems with i...
