Wireless Node Shared Channel Conflict Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face inefficiencies due to scheduling conflicts in shared channels used for transmitting control information, leading to potential cancellation or re-scheduling of channels, which can result in unnecessary re-transmissions and reduced overall system performance.
Innovation Solution
The method involves a wireless network node receiving scheduling requests, scheduling shared channels for information transmission, detecting conflicts, and resolving them by canceling or re-scheduling the shared channel to minimize conflicts and ensure efficient transmission of control information, often by allocating a separate channel for control information transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a shared channel is used to transmit both control information and data information, then spectral efficiency is improved, but scheduling conflicts occur leading to transmission reliability degradation
Solution Approach 1:
The patent segments the transmission resources by dividing the shared channel into distinct time slots: one for control information and another for data information. This segmentation resolves scheduling conflicts by ensuring that control and data transmissions do not overlap in time, thereby maintaining transmission reliability while still utilizing the shared channel for both purposes.
Solution Approach 2:
The patent implements dynamic resource allocation where the network device can flexibly adjust the timing and allocation of control and data channels based on current system conditions, buffer status, and traffic demands. This dynamic approach allows the system to adaptively resolve conflicts and optimize both spectral efficiency and transmission reliability under varying operational scenarios.
2Device complexity
If control information is transmitted in a shared channel, then device complexity is reduced, but unnecessary re-transmissions increase leading to productivity degradation
Solution Approach 1:
The patent applies preliminary action by having the network device proactively determine and indicate the specific time slot for control information transmission before the actual transmission occurs. This advance planning prevents scheduling conflicts and eliminates the need for re-transmissions, thereby maintaining high system productivity while keeping device complexity low through the use of a shared channel.
3Productivity
If the same time slot is allocated for both control and data transmission, then resource utilization is improved, but scheduling conflicts occur leading to loss of time
Solution Approach 1:
The patent implements periodic action by establishing a regular pattern where control information and data information are transmitted in alternating or sequentially assigned time slots within a frame structure. This periodic allocation ensures that both control and data transmissions receive dedicated time resources, preventing conflicts and avoiding scheduling delays while maintaining efficient resource utilization through structured time division.

AI summary
This disclosure relates to methods and devices for scheduling transmission of control information in wireless communication systems. In one implementation, the method includes receiving, by a wireless network node, a first scheduling request for a radio channel to transmit a first set of information. The method may also include scheduling, by the wireless network node, a first radio channel during a first time slot as a first shared channel for transmitting the first set of information in response to the first scheduling request, the first shared channel being shared by control information and the first set of information. The method may further include detecting, by the wireless network node, a conflict related to the first shared channel, and resolving, by the wireless network node, the conflict related to the first shared channel.
