Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If relay stations are deployed to expand communication coverage, then communication quality is improved, but device complexity increases
Solution Approach 1:
The relay station automatically acquires setting information for relay radio waves from the radio access network and configures its transmission parameters autonomously without requiring manual intervention, enabling self-configuration and reducing deployment complexity
Solution Approach 2:
The radio access network pre-configures and provides setting information to the relay station before the relay station begins operation, allowing the relay station to be properly configured in advance and simplifying the deployment process
2Reliability
If relay radio wave parameters are manually configured, then setup time is reduced, but relay quality cannot be optimized for varying network conditions
Solution Approach 1:
The system establishes a feedback mechanism where the relay station reports its status and the radio access network dynamically adjusts and provides updated setting information for relay radio waves, enabling continuous optimization of relay quality based on actual network conditions
Solution Approach 2:
The relay radio wave setting information is made dynamic rather than static, allowing the radio access network to update transmission parameters such as power, frequency, and beamforming settings in real-time according to changing network conditions and requirements

AI summary
A communication control apparatus includes processor that performs: by a relay station controller in a radio access network, controlling a relay station that relays communication between the radio access network and a communication device; by the relay station controller, providing the relay station with setting information concerning the relay radio wave to be transmitted by the relay station; and by a relay radio wave transmitter in the relay station, transmitting the relay radio wave based on the setting information. The relay radio wave setter provides the relay station with the setting information concerning at least one of the following for the relay radio wave to be transmitted by the relay station: coverage, allocation to a specific communication device, transmission power, beam type, beam width, number of beams, beam direction, frequency, frequency bandwidth, subcarrier spacing, symbol length, slot length, transmission time length, and transmission pattern.
