Time Domain Resource Assignment Table Adaptation for TBoMS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing time domain resource assignment methods for physical uplink shared channel (PUSCH) repetition types A and B are not compatible with transmission block processing over multi-slots (TBoMS), as they cannot redefine fields in the TDRA table to suit TBoMS mode effectively.
Innovation Solution
A method for time domain resource assignment that involves acquiring a TDRA table with a first field (e.g., L field) and a second field (e.g., repetition number field) to determine the length and repetition number of data transmission, allowing for compatible resource assignment across different transmission manners such as TBoMS, repetition, and TBoMS with repetition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing TDRA table for PUSCH repetition type B or type A is used, then time domain resource assignment can be performed for those repetition types, but it cannot be applied compatibly for TBoMS transmission mode
Solution Approach 1:
The patent makes the existing TDRA table structure universally applicable to multiple transmission modes (PUSCH repetition type A, type B, and TBoMS) by redefining the interpretation of existing fields rather than creating separate tables. The first field and second field are configured with values that can indicate different parameters depending on the transmission mode, allowing one table structure to serve multiple functions.
Solution Approach 2:
The patent changes the interpretation and mapping of parameters within the TDRA table fields based on the transmission mode. For TBoMS, the first field and second field values are mapped to indicate transmission block size and slot allocation differently than for repetition types, enabling the same table structure to adapt to different transmission requirements through parameter reconfiguration.
2Adaptability or versatility
If TDRA table fields are redefined to support TBoMS, then compatibility for TBoMS transmission is achieved, but the existing interpretation for repetition types may be affected
Solution Approach 1:
The patent introduces dynamic field interpretation where the meaning and mapping of TDRA table fields changes based on the transmission mode indicated by higher-layer configuration or DCI. The same first field and second field can represent different parameters (e.g., repetition number for type A/B, transmission block indicators for TBoMS) depending on the active transmission mode, ensuring accurate interpretation without conflict.
Solution Approach 2:
The patent uses transmission mode indicators (such as RRC configuration parameters or DCI fields) as intermediaries to disambiguate the meaning of TDRA table fields. These indicators act as mediators that tell the system how to interpret the first field and second field values, preventing confusion between different transmission mode requirements while maintaining a unified table structure.

AI summary
A method for time domain resource assignment is performed by a terminal device, and includes: acquiring a time domain resource assignment (TDRA) table, wherein the TDRA table includes a first field, and a second field corresponding to the first field; and performing time domain resource assignment according to the first field and the second field.
