Uplink Transmission Early Termination via TBoMS Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing communication technologies, terminals waste resources when transmitting uplink information over multiple slots based on TB processing over multi-slot PUSCH (TBoMS), as network devices decode information only after completing reception, leading to unnecessary power consumption and spectrum waste.
Innovation Solution
Implementing an early-termination-of-transmission indication mechanism, where the network device decodes uplink information from partial slots and sends an indication to the terminal to stop transmission, allowing the terminal to terminate the process and free resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal transmits uplink information over multiple slots based on TBoMS, then the coverage is improved for weak coverage scenarios, but the terminal resources (power and spectrum) are wasted when transmission continues even after successful decoding
Solution Approach 1:
The network device sends an early termination indication to the terminal as feedback when uplink information is successfully decoded before all allocated slots are used. This feedback mechanism allows the terminal to stop transmission early, avoiding unnecessary power consumption and spectrum waste while maintaining reliable communication in weak coverage scenarios.
Solution Approach 2:
The system allocates multiple slots for transmission (excessive action) to ensure reliable delivery in weak coverage, but enables partial action by allowing early termination when decoding succeeds. This resolves the contradiction by providing the option to use fewer resources than allocated when conditions permit, while maintaining the capability to use full allocation when needed.
2Measurement precision
If the network device waits to decode information only after completing reception of all slots, then decoding accuracy is maintained, but spectrum resources are wasted and terminal power is consumed unnecessarily
Solution Approach 1:
The network device performs preliminary decoding checks at intermediate points during slot reception rather than waiting until all slots are complete. When successful decoding is achieved in advance, the network device sends an early termination indication, thereby preserving decoding accuracy while avoiding unnecessary continuation of transmission and reducing spectrum waste.
3Reliability
If the terminal continues transmission over all allocated slots, then complete data delivery is ensured, but unnecessary power consumption occurs when information is already successfully received
Solution Approach 1:
The terminal receives feedback in the form of an early termination indication from the network device when data has been successfully decoded. This feedback allows the terminal to stop transmission early, ensuring complete data delivery while avoiding unnecessary power consumption that would occur if the terminal continued transmitting over all allocated slots regardless of reception status.
