Systems and methods for ofdm interference imbalance management

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 kand an inner loop that goes over the M dominant intra-frequency cells that IC are performed on, for each subcarrier set kthe noise plus interference power estimate of that set is initialized by N by setting: N(k)=N. The method includes, for each subcarrier set kthe 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(k) is not adjusted. When there is a collision the interference plus noise of that set N(k) is adjusted by removing the power contribution Eof that cell by applying the correction: N(k)=N(k)−E. The method includes looping over all considered cells M and when all adjustments are complete to N(k) for subcarrier set kthe program provides the adjusted N(k) output and exits the m loop.
