Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Telecommunication systems face inefficiencies due to high load and interference conditions, which can lead to suboptimal communication services, particularly when signal levels for wireless devices do not meet criteria, affecting data transmission quality.
Innovation Solution
Implementing coordinated multipoint transmissions, where access nodes schedule wireless resources using semi-persistent or delay-based scheduling based on the number of wireless devices meeting specific application requirements, to enhance signal quality and reduce interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If coordinated multipoint transmissions are implemented to improve signal quality for wireless devices, then data transmission quality is improved, but system complexity increases
Solution Approach 1:
The patent segments the transmission function by dividing it across multiple access nodes (MP points) rather than relying on a single node. Each access node handles a portion of the transmission to the wireless device, allowing the system to improve signal quality through coordinated multi-point transmission while distributing the complexity across multiple manageable components rather than concentrating it in one complex unit
Solution Approach 2:
The patent introduces a coordination mechanism that acts as an intermediary between multiple access nodes and the wireless device. This coordination entity manages the complex interactions and resource allocations, enabling coordinated multipoint transmissions to improve signal quality while containing system complexity within the coordination layer rather than propagating it throughout the entire system
2Productivity
If semi-persistent scheduling is used to manage wireless transmissions for multiple devices, then resource allocation efficiency is improved, but scheduling complexity increases
Solution Approach 1:
The patent implements semi-persistent scheduling where resource allocations are established periodically for groups of wireless devices rather than making individual scheduling decisions for each transmission. This periodic approach improves resource allocation efficiency by reducing scheduling overhead while managing complexity through standardized periodic patterns that can be predetermined and executed systematically
Solution Approach 2:
The patent merges the scheduling of multiple wireless devices into coordinated multipoint transmission groups, where devices with similar requirements are bundled together and handled by the same set of access nodes using the same scheduling pattern. This merging reduces the number of independent scheduling decisions needed, improving efficiency while containing complexity through consolidated management

AI summary
Systems and methods are described for scheduling wireless resources with coordinated multipoint transmissions. It may be determined that a signal level for a wireless device in communication with an access node does not meet a signal level criteria. Based on the determination, an access node may be instructed to transmit information to the wireless device using a coordinated multipoint transmission. A number of wireless devices in communication with the access node that comprise an application requirement that meets an application requirement criteria may further be determined. Then, the access node may be instructed to schedule wireless transmissions using at least one of semi-persistent scheduling and delay based scheduling based on the determined number of the plurality of wireless devices and the instruction to transmit using the coordinated multipoint transmission.
