Systems and methods for measuring interference reciprocity between uplink and downlink directions in a wireless communications system

摘要

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 104 and base stations 102 is measured. The correlation data is analyzed 106/107/111 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 104/102/101 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 102; and a computer 107/111 for analyzing the correlation.
