Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If advanced modulation and transmission mechanisms (OFDM, CDMA, TDMA) are implemented across multiple carriers, then resource allocation efficiency and signal timing alignment are improved, but system complexity and device configuration difficulty increase
Solution Approach 1:
The patent divides the multicarrier system into multiple component carriers, each independently configured with specific modulation and transmission mechanisms. This segmentation allows optimized resource allocation on each carrier while managing overall system complexity through modular configuration.
Solution Approach 2:
The patent implements dynamic modulation and coding schemes that can adaptively change parameters across different carriers based on channel conditions and traffic requirements. This dynamic adjustment improves resource allocation efficiency while the system manages complexity through standardized adaptation algorithms.
2Productivity
If carrier aggregation is implemented to enhance network performance, then throughput and resource utilization are improved, but signal timing alignment and synchronization challenges worsen
Solution Approach 1:
The patent implements feedback mechanisms where the network monitors signal timing and synchronization status across aggregated carriers, then adjusts transmission parameters accordingly. This closed-loop control maintains timing alignment precision while enabling carrier aggregation for improved throughput.
Solution Approach 2:
The patent performs preliminary synchronization and timing alignment procedures before activating carrier aggregation. This preliminary action establishes the necessary timing relationships in advance, preventing synchronization issues when multiple carriers are aggregated for enhanced performance.
3Adaptability or versatility
If tight interworking between 5G and LTE networks is implemented, then network flexibility and service capability are improved, but interoperability complexity and protocol management difficulty increase
Solution Approach 1:
The patent implements a unified protocol framework that enables the same system to operate across both 5G and LTE networks. This universal approach allows single device design to support multiple network types, improving flexibility while managing interoperability complexity through standardized interfaces and procedures.
Data Source
AI summary
A wireless device receives configuration parameters of a cell that comprise: first parameters indicating: configuration of SRSs of the cell; whether a first accumulated power control adjustment for the SRSs is enabled; and second parameters. The second parameters indicate: configuration of an uplink data channel of the cell; and whether a second accumulated power control adjustment for the uplink data channel is enabled. A first transmission power is determined for the SRSs based on the first accumulated power control adjustment and a first power control command. The SRSs are transmitted, via the cell, with the first transmission power. A second transmission power is determined for the uplink data channel of the cell based on the second accumulated power control adjustment and a second power control command. One or more transport blocks are transmitted, via the uplink data channel of the cell, with the second transmission power.
