Abstract
Methods and systems for measuring interference reciprocity between uplink and downlink directions in a wireless communications system. Correlation data between uplink and downlink interference, e.g., bit error rate, during transmissions between wireless terminals and base stations is measured. The correlation data is analyzed to determine if uplink and downlink reciprocity falls within a predetermined range. Adjustment criteria may be determined when reciprocity falls outside a predetermined range. Measurement may be automated for near real-time results. Systems include means for measuring correlation between uplink and downlink interferences during communication between a wireless terminal and a wireless base station controller ; and a computer for analyzing the correlation.
