Unified TDRA Table for Dynamic TB Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G NR technology faces limitations in efficiently managing transport block (TB) modes, particularly in dynamically switching between multiple TBs via a single grant and single TB repetition modes, which affects resource utilization and communication efficiency.
Innovation Solution
The implementation of a method that allows for dynamic switching between TB modes by using a single time domain resource allocation (TDRA) table, where a flag or column distinguishes between TB modes, enabling the UE and base station to switch between scheduling multiple TBs via a single grant and single TB repetition via a single grant, using RRC configurations and MAC-CE bits for control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate TDRA tables are used for multiple TB mode and single TB repetition mode, then each mode can be configured independently, but device complexity and configuration overhead increase
Solution Approach 1:
The patent combines multiple TB mode configurations and single TB repetition configurations into a single unified TDRA table. The table includes columns that indicate TB mode type, allowing the system to select and apply appropriate configurations from the same table structure, thereby reducing the number of separate tables needed and simplifying device complexity while maintaining adaptability.
Solution Approach 2:
The unified TDRA table is designed to serve multiple functions by incorporating configuration parameters for both multiple TB mode and single TB repetition mode within the same table structure. This universal table can be dynamically selected and applied based on the current operational mode, eliminating the need for separate dedicated tables for each mode.
2Productivity
If dynamic switching between TB modes is enabled, then communication efficiency improves, but processing overhead and complexity increase
Solution Approach 1:
The patent implements dynamic switching between multiple TB mode and single TB repetition mode by enabling the system to change operational modes based on real-time communication conditions and requirements. The unified TDRA table supports this dynamic behavior by providing pre-configured parameters that can be quickly selected and applied without extensive reconfiguration, thus improving communication efficiency while managing processing overhead.
3Reliability
If multiple TDRA tables are maintained for different TB modes, then mode-specific optimization is achieved, but memory usage and configuration overhead increase
Solution Approach 1:
The patent merges configuration data for different TB modes into a single TDRA table structure, reducing the total volume of configuration data that needs to be stored and managed. By using a unified table with mode identification columns, the system maintains mode-specific optimization while minimizing memory usage and configuration overhead compared to maintaining separate tables for each mode.

AI summary
The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. The apparatus may receive an indication of at least one TDRA table for one of a plurality of TB modes for communication with the base station, the plurality of TB modes including at least one of a first TB mode or a second TB mode, the first TB mode corresponding to multiple TBs via a single grant, the second TB mode corresponding to a single TB with at least one repetition via the single grant. The apparatus may also apply, based on the at least one TDRA table, the one of the plurality of TB modes for the communication with the base station. Additionally, the apparatus may transmit uplink data, or receive downlink data, based on the one of the plurality of TB modes.
