UE Dynamic Channel Code Switching for 5G

The patent implements dynamic channel code switching by enabling the UE to adaptively select between different channel codes (e.g., TC for LTE, TBCC for NB-IoT, LDPC for 5G NR) based on real-time network conditions and received configurations. This dynamic adaptation allows the UE to optimize its decoding capability for different RATs and service requirements while maintaining a unified hardware architecture that supports multiple codes, thereby resolving the contradiction between adaptability and device complexity.

The patent designs a universal channel code support architecture where a single UE can handle multiple channel codes (TC, TBCC, LDPC, polar codes) through a unified processing framework. The UE receives configurations from the base station that indicate which channel code to use for specific RATs and services, enabling multi-functionality without requiring separate hardware for each code type. This universal approach maintains relatively low device complexity while significantly improving communication efficiency across different RATs by selecting the most appropriate channel code for each scenario.

The patent implements parameter-based channel code selection where the UE changes its decoding parameters (channel code type, code rate, block length) based on network configurations and service requirements. By dynamically adjusting these parameters rather than maintaining all decoding capabilities at full power, the UE can maximize its capability when needed while consuming less energy during normal operation. The base station provides configurations that guide the UE in selecting appropriate parameters, enabling efficient energy management while maintaining full capability availability.
