TDRA Table Configuration for TBoMS on Special Time Slots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing time domain resource assignment methods for physical uplink shared channels (PUSCH) fail to support the transmission of transport blocks over multiple slots (TBoMS) on special time slots, leading to resource wastage and inefficient coding.
Innovation Solution
A method and apparatus for determining target time domain resources on special time slots using a modified TDRA table, allowing accurate allocation and transmission of TBoMS, thereby improving coding efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the existing TDRA table similar to PUSCH repetition type A is used for time domain resource assignment, then the time domain resource assignment can be performed according to the existing standard, but the transmission of TBoMS on special time slots cannot be performed, resulting in waste of time-domain resources
Solution Approach 1:
The patent applies dynamics by making the TDRA table configurable and adaptable. Instead of using a fixed TDRA table similar to PUSCH repetition type A, the system dynamically configures the TDRA table to support both traditional PUSCH transmissions and TBoMS transmissions on special time slots. This allows the resource assignment mechanism to adapt to different transmission modes and time slot types, eliminating resource waste while maintaining backward compatibility.
2Reliability
If the TDRA table is configured to support TBoMS transmission on special time slots, then the coding efficiency is improved, but the complexity of resource assignment increases
Solution Approach 1:
The patent applies parameter changes by modifying the TDRA table configuration to include parameters specific to TBoMS transmission on special time slots. The TDRA table is enhanced with fields that indicate whether a time slot is a special time slot and provide appropriate resource assignment parameters for TBoMS. This allows the system to maintain a unified TDRA table structure while supporting multiple transmission modes through parameter differentiation, avoiding the need for separate complex assignment mechanisms.
3Ease of operation
If a unified TDRA table is used for both traditional PUSCH and TBoMS transmissions, then the ease of operation is improved, but the precision of resource assignment for special time slots may be compromised
Solution Approach 1:
The patent applies segmentation by dividing the TDRA table into different sections or rows that correspond to different transmission modes. The TDRA table includes specific entries for traditional PUSCH transmissions and separate entries for TBoMS transmissions on special time slots. Each segment contains mode-specific parameters, allowing the system to maintain a unified table structure for ease of operation while ensuring precise resource assignment for each transmission type through dedicated parameter sets.

AI summary
A time domain resource assignment method is performed by a terminal device, and includes: obtaining a time domain resource assignment (TDRA) table in response to a current time slot being a special time slot, wherein the current time slot is configured for transmitting a transport block (TBoMS) over a plurality of time slots; and determining a target time domain resource for transmitting the TBoMS on the special time slot according to the TDRA table.
