Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different radio access techniques are used for different purposes, then various communication requirements can be met, but there is no unified framework to switch among them efficiently
Solution Approach 1:
The patent creates a unified radio access framework where a single system can perform multiple access techniques (SCMA, OFDMA, CDMA, NOMA, MU-MIMO) by dynamically configuring parameters such as spreading factor, codebook size, and resource allocation. This multi-functional approach eliminates the need for separate dedicated systems for each access technique while maintaining the ability to adapt to different communication requirements.
Solution Approach 2:
The system implements dynamic parameter adjustment mechanisms that allow real-time switching between different radio access techniques. By dynamically modifying parameters like spreading factor, codebook dimensions, and resource block allocation based on current communication conditions, the system can adaptively select the most appropriate access technique without requiring static configuration for each technique.
2Reliability
If access modes are fixed to meet specific criteria, then optimization for particular scenarios is achieved, but flexibility to adapt to changing requirements is reduced
Solution Approach 1:
The patent employs systematic parameter changes to enable transitions between different access modes. By defining specific parameter configurations (such as spreading factor values, codebook sizes, resource allocation patterns) that correspond to different access techniques, the system can reliably optimize for specific scenarios while maintaining the capability to change parameters and adapt to new requirements when conditions change.
3Productivity
If scalable digital communications with adaptive parameters are implemented, then communication performance is enhanced, but system parameter management complexity increases
Solution Approach 1:
The system pre-defines parameter configurations and mapping rules that associate specific parameter sets with particular access modes and communication scenarios. This preliminary preparation of parameter combinations allows the system to quickly switch between modes by simply selecting pre-configured parameter sets rather than independently tuning multiple parameters, thereby reducing the operational complexity of parameter management while maintaining scalable and adaptive communication performance.

AI summary
A method for operating an adapting device includes selecting a first access mode out of a plurality of access modes for a first transmission between a first communications device and a second communications device, wherein the selection of the first access mode is made in accordance with an access mode criterion, and at least one of communications system information, and user equipment information, and determining sparse code multiple access (SCMA) parameters from the first access mode in accordance with a SCMA parameter mapping rule. The method also includes providing information about the first access mode to at least one of the first communications device and the second communications device.
