Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, overlapping uplink channels in the time domain lead to challenges in ensuring normal data transmission.
Innovation Solution
A method is provided where the transmission of a second channel is determined based on a first channel with higher priority, ensuring consistent understanding between terminal and network devices, thereby maintaining normal channel transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple uplink channels are transmitted simultaneously in the time domain, then transmission efficiency is improved, but transmission conflicts and data loss increase
Solution Approach 1:
The patent applies preliminary action by establishing a priority relationship between channels before time-domain overlap occurs. The network device determines priority levels for different uplink channels in advance, and the terminal device uses these pre-established priorities to resolve potential conflicts when channels overlap in time, thereby avoiding transmission failures before they occur.
Solution Approach 2:
The patent changes the parameter of channel transmission by introducing priority as a distinguishing characteristic. When multiple channels overlap in the time domain, the system changes the transmission parameter from simultaneous equal-priority transmission to selective transmission based on priority levels, allowing higher-priority channels to be transmitted while lower-priority channels are cancelled or postponed.
2Reliability
If channel priority rules are implemented to resolve overlaps, then transmission reliability is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing uplink channels into different priority levels or categories. The network device segments channels based on their importance and transmission requirements, assigning different priority levels to different channel types. This segmentation simplifies the conflict resolution process by creating clear hierarchical rules rather than requiring complex arbitration mechanisms.
Solution Approach 2:
The patent introduces priority determination as an intermediary mechanism between channel scheduling and transmission execution. The network device determines and communicates priority information as an intermediary parameter, which then mediates the conflict resolution process at the terminal device, simplifying the overall channel management complexity through a clear decision-making framework.
3Speed
If terminal device determines channel cancellation independently, then response speed is improved, but understanding consistency with network device deteriorates
Solution Approach 1:
The patent applies feedback by having the network device determine and communicate priority information to the terminal device. The terminal device uses this feedback information (priority determination from network device) to make consistent cancellation decisions. This feedback mechanism ensures that both devices have the same understanding of channel priorities while maintaining fast response capability.
Solution Approach 2:
The patent uses preliminary action by having the network device determine priority relationships in advance before actual transmission conflicts occur. The terminal device receives this pre-determined priority information and uses it to make consistent cancellation decisions, ensuring both devices understand the same rules without requiring real-time complex negotiations.

AI summary
Provided are a wireless communication method and device. The method includes: determining, based on a first channel, whether to cancel transmission of a second channel. The first channel is determined based on at least one initial channel, and each initial channel of the at least one initial channel has a priority higher than a priority of the second channel. Whether to cancel the transmission of the second channel is determined based on the first channel, and the first channel is determined based on at least one initial channel. That is, the first channel that is used to determine whether to trigger to cancel transmission of the second channel is determined based on the at least one initial channel, which can ensure that the terminal device and the network device have consistent understandings of the first channel that is used to trigger whether to cancel transmission of the second channel.
