Application: Rf channel control device, base station device, and rf channel control method performed by same (Patent ID: US20240129850A1)
The patent filed by SK Telecom Co Ltd. proposes a new technical method for dynamically controlling an RF channel in an O-RAN system to optimize throughput and energy efficiency. The method involves collecting information for a cell and using a controller to determine the RF channel control method based on specific values identified from a variety of applicable methods. These values include expected performance degradation, energy consumption reduction, and cell state, which are calculated using collected information such as radio resource use rates, throughput, number of connected UEs, and energy consumption.
The RF channel control device described in the patent includes features such as determining control methods based on predefined conditions related to network load, energy consumption reduction, and performance degradation. The device can apply methods like turning off specific Tx/Rx arrays, adjusting Tx power, and managing signal transmissions to optimize RF channel control. Additionally, the patent covers a distributed unit (DU) and radio unit (RU) for implementing the control commands and reconfiguring the RF channel accordingly. Overall, the patent introduces a comprehensive approach to dynamically and optimally controlling RF channels in O-RAN systems based on specific values derived from collected information.
