Constellation Superposition Signaling for Shared Radio Resources

The patent segments the communication system into multiple user groups (first set of UEs and second set of UEs) that can be served simultaneously through different modulation schemes. This segmentation allows the system to handle multiple communication tasks in parallel, increasing overall communication capacity without requiring a complete redesign of the communication structure.

The patent introduces a new dimension of modulation order differentiation, where different users are assigned different modulation schemes (e.g., first modulation scheme for first set of UEs, second modulation scheme for second set of UEs). This dimensional change in the communication structure enables the system to serve multiple users with different service requirements simultaneously, thereby increasing communication capacity and flexibility.

The patent applies local quality by assigning different modulation schemes to different user groups based on their specific requirements. The first set of UEs receives signals with a first modulation scheme while the second set of UEs receives signals with a second modulation scheme. This localized differentiation allows efficient resource sharing while simplifying interference management, as each user group is optimized for its specific service requirements rather than using a uniform approach.

The patent converts the potential harm of interference into a benefit by using different modulation schemes for different user groups. The interference that would normally degrade performance is actually utilized to enable simultaneous service to multiple users with different modulation requirements. The system transforms the interference challenge into an opportunity for multi-user superposition transmission, where the superposition of differently modulated signals carries information for multiple users simultaneously.

The patent implements dynamics by making the modulation scheme assignment flexible and adaptive rather than fixed. The system can dynamically assign different modulation schemes to different user groups based on current channel conditions, service requirements, and traffic demands. This dynamic approach allows the system to optimize communication speed for users requiring high data rates while simultaneously accommodating users with lower speed requirements, thereby maintaining both high communication speed and system flexibility.

The patent achieves universality by designing a communication system that can handle multiple modulation schemes within a single framework. The base station is configured to support both first modulation scheme and second modulation scheme, allowing it to serve diverse user requirements through a unified system. This multi-functional capability enables the system to provide high-speed communication for users needing advanced modulation while simultaneously supporting users with simpler requirements, thus improving communication speed without sacrificing flexibility.
