MEASUREMENT-ASSISTED DYNAMIC FREQUENCY -REUSE IN CELLULAR TELECOMMUNICATIONS NETWORKS

摘要

A RADIO NETWORK RESOURCE CONTROLLER (203) DIRECTS (801) A FIRST NETWORK NODE ASSOCIATED WITH A FIRST CELL REGION, OR A WIRELESS TERMINAL IN COMMUNICATION THROUGH THE FIRST CELL REGION, TO MEASURE AND REPORT RADIO RESOURCE-RELATED DATA SELECTED FROM THE GROUP CONSISTING OF: RESOURCE ACTIVITY PER CHANNEL; THE NUMBER OF TRANSMITTED POWER SAMPLES THAT EXCEED A THRESHOLD OVER A MEASUREMENT PERIOD; AND, CHANNEL QUALITY SAMPLES THAT EXCEED A QUALITY THRESHOLD. THE CONTROLLER (203) THEN RECEIVES (802) AT LEAST ONE MEASUREMENT REPORT OF THE RADIO RESOURCE-RELATED DATA AND, AS A FUNCTION OF THE RADIO RESOURCE-RELATED DATA IN THE FIRST CELL REGION, DYNAMICALLY REALLOCATES (803) THE DISTRIBUTION OF RESOURCES, SUCH AS RADIO-FREQUENCY CHANNELS ASSOCIATED WITH UPLINK AND DOWNLINK COMMUNICATIONS, BETWEEN THE FIRST CELL REGION AND AT LEAST A SECOND CELL REGION. THE INVENTION HAS A PARTICULAR ADVANTAGE IN TIME DIVISION DUPLEX (TDD) MODE OF OPERATION WHERE EFFICIENT AND DYNAMIC INTERFERENCE MITIGATION IS NEEDED TO COMBAT THE INHERENT MOBILE-TO-MOBILE AND BASE STATION-TO-BASE STATION INTERFERENCE.
