Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In New Radio (NR) technology, the existing TB over multiple slots (TBoMS) method faces challenges in maintaining stable transmission power, leading to inefficiencies and potential interference due to unstable power conditions during data transmission.
Innovation Solution
A multi-time interval data transmission method where the User Equipment (UE) determines the difference between current and initial transmission power, comparing it to preset thresholds to decide whether to continue or cancel data transmission, thereby optimizing power usage and reducing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-time interval transmission is used to improve coverage and reliability, then data transmission reliability is improved, but transmission power stability deteriorates
Solution Approach 1:
The base station pre-configures transmission power parameters including initial transmission power, power difference thresholds, and maximum transmission time interval counts before the actual data transmission begins. This preliminary configuration enables the UE to make real-time transmission decisions without complex calculations during the transmission process, maintaining power stability while ensuring reliable multi-time interval transmission.
Solution Approach 2:
The UE continuously monitors the difference between current and initial transmission power in each time interval, comparing it against pre-configured thresholds. Based on this feedback mechanism, the UE dynamically adjusts transmission behavior - continuing transmission when power difference is within thresholds, or stopping transmission when thresholds are exceeded. This feedback loop maintains power stability while achieving reliable data transmission across multiple time intervals.
2Reliability
If transmission continues in all time intervals to ensure complete data parsing, then data transmission reliability is improved, but power consumption increases
Solution Approach 1:
The base station pre-configures the maximum number of transmission time intervals and power difference thresholds before transmission begins. The UE uses these pre-set parameters to make quick decisions about whether to continue or stop transmission in each interval, avoiding unnecessary power consumption while ensuring reliable data delivery within the configured limits.
Solution Approach 2:
Instead of transmitting in all possible time intervals, the UE transmits only as many time intervals as needed based on power conditions. When the power difference exceeds thresholds or the maximum interval count is reached, transmission stops early. This partial action approach reduces unnecessary power consumption while still achieving reliable data transmission when conditions permit.

If transmission power is adjusted dynamically to optimize power usage, then power consumption is reduced, but transmission efficiency deteriorates
Solution Approach 1:
The base station pre-configures all necessary transmission parameters including initial power levels, power difference thresholds, and maximum interval counts before transmission begins. This eliminates the need for complex real-time power optimization calculations at the UE, maintaining high transmission efficiency while achieving dynamic power adjustment through simple threshold comparisons.
Solution Approach 2:
The system changes transmission parameters (power levels, transmission continuation decisions) based on pre-configured threshold values. The UE compares current power differences against these parameters and adjusts transmission behavior accordingly. This parameter-based approach enables efficient power management without compromising transmission efficiency, as decisions are made through simple comparisons rather than complex real-time optimization.
