Application: Control device for transmission power control in cell-free massive mimo system composed of many antennas, terminal device, control method, and computer-readable storage medium (Patent ID: US20240214944A1)
The patent filed by KDDI Corp. describes a control device and method in a radio communication system that provides a communication service to a terminal device via multiple antennas. The control device notifies the terminal device of information to identify specific radio signals for transmission power control. This information includes details about the antennas used, the number of antennas, reference values for radio quality, and indices for radio quality measurement.
Furthermore, the terminal device, equipped with processors and memories, receives this information from the control device and measures the radio quality of the identified signals to control transmission power accordingly. The terminal device also considers the number of antennas, reference values for radio quality, and indices provided by the control device to optimize transmission power control. Overall, the system and method outlined in the patent aim to enhance communication services by enabling efficient transmission power control based on identified radio signals and their quality metrics.
