Title:
RUNTIME ADJUSTMENT AND SEQUENTIAL CALIBRATION OF DISPLAY COMMUNICATION INTERFACE DRIVE STRENGTH TO IMPROVE WIRELESS NETWORK SIGNAL QUALITY
Document Type and Number:
WIPO Patent Application WO/2023/023887
Kind Code:
A1
Abstract:
Systems, methods, and apparatus for controlling radio frequency, RF, interference at a mobile communication device are described. A data communication apparatus has a wireless transceiver configured to transmit and receive RF signals, a bus interface circuit coupled to a serial bus and configured for operation as a display serial interface, DSI) and a controller. The controller is configured to receive (1202) a measurement of a reference signal representative of RF signal quality at the mobile communication device, determine (1204) whether the measurement of the reference signal indicates that the RF signal quality is less than a minimum RF signal quality level, and reduce (1206) signal strength of a transmitter in the bus interface circuit when the RF signal quality falls below the minimum RF signal quality level.
