Terminal Buffer Storage for Transport Block Decoding Failures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The efficiency of determining and storing the number and sizes of Transport Blocks (TBs) that fail to be decoded in terminal equipment is low due to the limited time for base stations to occupy unlicensed carriers in shared wireless cellular systems, especially when using Carrier Aggregation technology.
Innovation Solution
A data storage method where a base station predefines a parameter indicating the minimum number of TBs to be stored by the terminal equipment when decoding failures exceed this parameter, allowing the terminal equipment to store at least this number without determining the exact number based on aggregated carriers, thereby improving storage efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the terminal equipment determines the number of TBs to store based on the number of aggregated carriers, then the storage method is simple, but the storage efficiency is low due to limited base station occupancy time on unlicensed carriers
Solution Approach 1:
The patent changes the parameter used for determining TB storage quantity from 'number of aggregated carriers' to a 'predefined parameter' provided by the base station. This parameter change allows the terminal to store TBs more efficiently without complex calculations, directly addressing the low storage efficiency problem while maintaining simplicity.
Solution Approach 2:
The base station provides a predefined parameter in advance that indicates the minimum number of TBs to store. This preliminary action eliminates the need for the terminal to perform complex real-time calculations based on carrier aggregation, thereby improving storage efficiency while keeping the determination method simple.
2Reliability
If the terminal equipment stores all failed TBs without a predefined parameter, then the buffer space is fully utilized, but the storage efficiency and buffer space utilization are reduced due to limited base station occupancy time
Solution Approach 1:
The base station provides feedback through the predefined parameter that indicates the minimum number of TBs to store. This feedback mechanism allows the terminal to store an appropriate number of TBs without over-utilizing buffer space, thereby improving storage efficiency while maintaining data transmission reliability.
Solution Approach 2:
The patent introduces a predefined parameter that changes the storage strategy from storing all failed TBs to storing a minimum number of TBs as indicated by the parameter. This parameter change optimizes buffer space utilization and improves storage efficiency while ensuring reliable data transmission.
3Quantity of substance
If the base station occupies unlicensed carrier for longer time, then more TBs can be transmitted, but the time for base station to occupy carrier is limited in shared wireless cellular systems
Solution Approach 1:
The patent changes the approach to determining TB storage quantity from based on carrier aggregation to based on a predefined parameter. This parameter change allows the terminal to store TBs efficiently within the limited base station occupancy time on unlicensed carriers, maximizing the number of TBs transmitted without extending occupancy time.

AI summary
There is provided a method for data storage, comprising: a terminal device receives configuration signaling transmitted by a base station; the terminal device determines a first parameter according to the configuration signaling, wherein when the number of unsuccessfully decoded transport blocks (TBs) received by the terminal device is not less than the first parameter, the number of TBs stored by the terminal device in a buffer is not less than the first parameter. In this way, the terminal device can determine unsuccessfully decoded TBs to be stored according to the first parameter indicated by the configuration signaling transmitted by the base station when the number of the received unsuccessfully decoded TBs is not less than the first parameter, so that the utilization efficiency of a storage space can be improved.
