Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If current cellular network frequency is used, then existing devices can communicate, but network frequency is saturated and throughput is limited
Solution Approach 1:
The patent transitions from traditional licensed spectrum to unlicensed spectrum (mmWave frequencies), effectively moving to a different dimension of the electromagnetic spectrum. This allows the system to access previously unavailable high-bandwidth frequencies, thereby increasing network throughput without being constrained by the saturation of traditional licensed bands.
Solution Approach 2:
The patent implements multi-RAT (Radio Access Technology) support, allowing the UE to operate across multiple spectrum types (licensed and unlicensed) and multiple access technologies (5G-NR, MulteFire, Wi-Fi). This multi-functionality enables the system to dynamically select and aggregate resources from different spectrum domains, thereby overcoming the limitations of any single frequency band.
2Productivity
If 5G-NR and MulteFire technologies are implemented, then throughput and coverage are increased, but device complexity and configuration difficulty increase
Solution Approach 1:
The patent introduces a network controller (OAM - Operations, Administration, and Maintenance entity) as an intermediary that centrally manages and coordinates the complex multi-RAT relay configurations. This intermediary automates the discovery, selection, and configuration of relay services, shielding the end user from the underlying complexity while enabling advanced throughput-enhancing features.
Solution Approach 2:
The patent implements automated relay service configuration where the UE and network entities autonomously perform discovery, capability exchange, and parameter configuration without manual intervention. The system self-organizes the multi-RAT relay connections, dynamically adapting to available resources and conditions, thereby reducing operational complexity despite the advanced technologies employed.
3Productivity
If unlicensed spectrum is utilized, then bandwidth and throughput are enhanced, but latency and resource coordination challenges increase
Solution Approach 1:
The patent merges licensed and unlicensed spectrum resources through carrier aggregation and dual-connectivity mechanisms. By combining the reliable, low-latency characteristics of licensed spectrum with the high bandwidth of unlicensed spectrum, the system achieves both high data transmission rates and acceptable latency performance, as traffic can be dynamically routed across both spectrum types.
Solution Approach 2:
The patent implements dynamic resource allocation and adaptive transmission schemes that continuously monitor channel conditions, latency requirements, and spectrum availability. The system dynamically adjusts modulation schemes, coding rates, and resource partitioning between licensed and unlicensed carriers, optimizing the balance between throughput and latency in real-time based on current network conditions.
Data Source
AI summary
A computer-readable storage medium that stores instructions for execution by one or more processors of a UE. The instructions to configure the UE for a UE-to-UE relay operation in a 5G NR system and to cause the UE to perform operations comprising encoding a registration request for transmission to an AMF of the 5G NR system. The registration request indicates a 5G ProSe capability of the UE as a UE-to-UE relay. A UE policy container received from the AMF is decoded. The UE policy container includes 5G ProSe UE-to-UE relay information. The 5G ProSe UE-to-UE relay information is provisioned by a Policy Control Function (PCF) of the 5G NR system in response to the registration request indicating the 5G ProSe capability. The UE is configured as a ProSe UE-to-UE relay in the 5G NR system based on the 5G ProSe UE-to-UE relay information.
