Abstract
Disclosed are example embodiments of systems and methods for an interference imbalance manager (IIM). The method includes an outer loop that goes over the K subcarrier sets ki and an inner loop that goes over the M dominant intra-frequency cells that IC are performed on, for each subcarrier set ki the noise plus interference power estimate of that set is initialized by N by setting: N(ki)=N. The method includes, for each subcarrier set ki the IIM determine when the pilots of each cell m collide with that subcarrier set. When there is no collision, the interference plus noise of that set N(ki) is not adjusted. When there is a collision the interference plus noise of that set N(ki) is adjusted by removing the power contribution Em of that cell by applying the correction: N(ki)=N(ki)−Em. The method includes looping over all considered cells M and when all adjustments are complete to N(ki) for subcarrier set ki the program provides the adjusted N(ki) output and exits the m loop.
