Channel Collision Handling via Priority Multiplexing in R16 Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the R16 wireless communication system, there is no specific solution for handling conflicts between physical channels of multiple communication links, which affects the performance of the communication system.
Innovation Solution
A method is introduced to detect channel collisions in physical channels, determine priorities based on channel types and information carried, and either multiplex or discard information from lower-priority channels to higher-priority channels to resolve conflicts, thereby improving communication system performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple physical channels are transmitted simultaneously in multi-TRP communication, then communication coverage and reliability are improved, but channel collision and interference occur between physical channels
Solution Approach 1:
The patent changes the parameter of physical channel transmission by introducing priority levels and time-frequency resource allocation mechanisms. When channel collision is detected, the system adjusts transmission parameters such as power levels, time slots, or frequency resources based on channel priorities, allowing high-priority channels to maintain transmission while low-priority channels are deferred or multiplexed, thus resolving the contradiction between maintaining reliable multi-channel communication and avoiding harmful collisions
Solution Approach 2:
The patent introduces an intermediary mechanism in the form of a channel collision handling protocol that mediates between conflicting physical channels. This intermediary layer detects collisions, determines channel priorities, and coordinates transmission adjustments, acting as a mediator that allows multiple channels to coexist reliably while preventing harmful interference through structured resource management
2Object-affected harmful factors
If physical channels are prioritized and multiplexed to resolve collisions, then channel conflict is reduced, but information loss occurs from discarding low-priority channel data
Solution Approach 1:
The patent applies merging by multiplexing information from low-priority physical channels into high-priority channels when collisions occur. Instead of simply discarding low-priority data, the system combines or embeds this information into available resources of higher-priority channels, reducing information loss while still resolving the channel conflict through priority-based resource allocation
Solution Approach 2:
The patent implements a discarding and recovering mechanism where information from low-priority channels that cannot be multiplexed is temporarily discarded, but the system is designed to recover this information through retransmission or alternative routing when channel conditions improve, thus minimizing permanent information loss while effectively managing channel conflicts

AI summary
An information sending method, a user terminal and a computer-readable storage medium are provided. The method comprises: determining whether physical channels in target information exist channel collision, in response to detecting an instruction for sending target information; determining a priority corresponding to each physical channel in the target information, in response to existing channel collision in the target information; processing the target information based on the priority of each physical channel in the target information, wherein said processing the target information comprises: multiplexing information carried by a physical channel with a lower priority in the target information to a physical channel with a higher priority in the target information; or, discarding the information carried by a physical channel with a low priority in the target information; and sending processed target information.
