Uplink Signal Priority Handling for Overlapping Resource Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems fail to distinguish the priority of signals carrying different services, such as eMBB and URLLC, leading to conflicts and unsatisfied transmission demands.
Innovation Solution
Implementing a method to determine and compare the priority of overlapping uplink signals using priority indices, allowing for transmission, separate transmission, or multiplexing based on priority levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the physical layer transmits signals without distinguishing priority, then the system maintains simple signal processing, but transmission conflicts occur between services of different priorities
Solution Approach 1:
The patent introduces priority parameters (priority indices) to characterize uplink signals, transforming the signal transmission process from a uniform treatment to a differentiated one based on priority levels. This allows the physical layer to distinguish between different services (eMBB, URLLC, mMTC) and resolve transmission conflicts by comparing priority parameters, thereby improving transmission reliability without excessive complexity increase.
Solution Approach 2:
The patent segments the signal transmission process into different priority levels, dividing uplink signals into multiple categories based on their priority indices. This segmentation enables the system to handle high-priority signals (such as URLLC) separately from low-priority signals (such as eMBB), ensuring that critical transmissions are not blocked by lower-priority traffic, thus resolving the contradiction between reliability and complexity.
2Reliability
If the system waits for eMBB signal transmission to complete before transmitting URLLC signal, then eMBB transmission completeness is maintained, but URLLC latency requirement is violated
Solution Approach 1:
The patent applies preliminary action by pre-assigning priority indices to different uplink signals based on their service requirements. Before transmission conflicts occur, the system has already determined the priority levels, enabling rapid decision-making when overlaps are detected. This preliminary classification allows the system to immediately prioritize URLLC signals over eMBB signals without waiting for eMBB completion, thus reducing latency while maintaining service completeness through appropriate handling.
Solution Approach 2:
The patent introduces dynamic signal handling based on priority comparison. When time-frequency resources overlap, the system dynamically adjusts transmission behavior by comparing priority indices and selecting the higher-priority signal for transmission. This dynamic approach allows the system to switch from waiting for eMBB completion to immediately transmitting URLLC signals when needed, resolving the contradiction between transmission completeness and latency requirements.
3Adaptability or versatility
If the physical layer distinguishes signal priority using multiple indices, then transmission conflict resolution capability is improved, but the complexity of priority management increases
Solution Approach 1:
The patent creates a universal priority index framework that can accommodate multiple services (eMBB, URLLC, mMTC) with different requirements through a single standardized mechanism. By defining a common priority index system that works across all service types, the patent achieves versatile service differentiation without requiring separate complex management systems for each service, thus balancing adaptability with manageable complexity.

Signal transmission and reception methods and apparatuses. The method includes: determining by a terminal equipment that a time-frequency resource of a first uplink signal and a time-frequency resource of a second uplink signal at least partially overlap in a time domain or a time-frequency domain; comparing the first uplink signal and the second uplink signal, the comparing at least comprising comparing a first priority of the first uplink signal and a first priority of the second uplink signal, the first priority being related to content carried or indicated by an uplink signal; and transmitting the first uplink signal and/or the second uplink signal to a network device.
