Abstract
A small cell interference coordination method and wireless communication device. The method includes: obtaining mobile information of at least one of the small cells; determining relative movement between the small cells according to at least the movement information; estimating a Doppler frequency shift of a signal between small cells according to the relative movement; and implementing an interference alignment policy between small cells according to the estimated Doppler frequency shift.

An electronic device in a wireless communication system, comprising:
- circuitry, configured to:
- obtain movement information of a first cell and/or a second cell;
- determine a relative moving condition between the first cell and the second cell based on the movement information;
- estimate a doppler shift of a signal between the first cell and the second cell based on the relative moving condition;
- and
- perform interference mitigation between the first cell and the second cell based on the estimated doppler shift when signal coverage range of the first cell and the second cell overlap,
- wherein the interference mitigation comprises adjusting a frequency of a signal of the first cell to shift the interference between the first cell and the second cell to specific transmission resources.
