The most ofICI avoidance algorithms divide UEs into
cell edge and cell centre users based on static thresholds
such as path loss, SINR and geometry factors. However, in
an actual communication environment, the UE distribution
as well as the shape of a cell can be changed. Therefore
selection of the cell edge bands is difficult and needs to be
optimized according to the time variation environment.
Reference [6] proposed an ICI avoidance algorithm that can
change cell edge bands dynamically. For each active UE and
every time gap (the update duration of CEU/CCU), the
threshold is updated based on SINR in order to keep the
ratio of number of CEUs and CCUs constant. Then, cell
weight is calculated to follow the instant changing of
network.
