Application: Communication system (Patent ID: US20230422139A1)

The patent filed by Mitsubishi Electric Corp. focuses on simplifying radio resource management in a communication system where a cell is spatially separated by multiple radio beams served by a base station device. The base station device shares a radio resource control (RRC) parameter between the different radio beams to be applied to a communication terminal device. The communication system described in the patent includes a user apparatus and a base station that configures at least one serving cell for wireless communication with the user apparatus. The base station transmits information related to the beams used in the serving cell to the user apparatus using RRC signaling. The user apparatus can perform measurements on each beam and transmit the results to the base station for further communication optimization.

Additionally, the base station can transmit information related to beams configured by a secondary cell (SCell) within the serving cell, as well as MAC control information indicating the activation or deactivation of the beams. The patent also covers the roles of the base station and user apparatus separately, detailing how the base station transmits beam-related information using RRC signaling, while the user apparatus receives this information and conducts wireless communication based on it. Overall, the patent aims to enhance radio resource management efficiency in a communication system with spatially separated cells and multiple radio beams, improving the overall performance and reliability of wireless communication.
