Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In next-generation mobile communication systems, the varying number of resource elements (REs) within slots or mini-slots poses challenges for determining optimal transport block sizes (TBS) and modulation coding schemes (MCS), leading to efficiency degradation when using methods similar to those in LTE/LTE-A.
Innovation Solution
A method for determining TBS by calculating a value based on the number of REs and code rate, comparing it to a threshold, and using either a predetermined table or mathematical function, including quantization, to efficiently select TBS and MCS for uplink and downlink transmissions.

Engineering Contradiction Analysis
1Productivity
If the same TBS determination method as LTE/LTE-A is used, then implementation simplicity is maintained, but efficiency is degraded due to varying RE numbers in next-generation systems
Solution Approach 1:
The patent applies parameter changes by switching between two different TBS determination methods based on the calculated value threshold. When the calculated value is below the threshold, a first determination method is used; when above, a second determination method is applied. This dynamic parameter adjustment optimizes communication efficiency for varying RE numbers while managing system complexity through conditional logic.
2Adaptability or versatility
If a single TBS determination method is used for all cases, then implementation is simpler, but adequate measures cannot be taken for diverse situations
Solution Approach 1:
The patent implements dynamics by making the TBS determination method adaptive rather than static. The system dynamically selects between different determination approaches based on the calculated value compared to a threshold, allowing the TBS determination process to adapt to diverse RE configurations in next-generation communication systems while maintaining manageable complexity through structured decision logic.

AI summary
A disclosure of this specification provides a method performed by a wireless device for determining a transport block size (TBS). The method may include the steps of determining a number of resource elements (REs) within a slot, calculating a value related to the TBS, based on the determined number of REs and a code rate, comparing the calculated value with a pre-determined threshold value, determining the TBS according to the comparison, wherein, if the calculated value is smaller than or equal to the pre-determined threshold value, the TBS may be determined using a predetermined table.
