Cooperative Wireless Uplink Pooling for Cell-Edge Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless devices experience decreased uplink performance and quality of service (QoS) when moving away from an access node, particularly in areas with poor radio frequency (RF) conditions, leading to potential handovers that cause delays and resource consumption.
Innovation Solution
Forming dynamic groups of wireless devices within a threshold proximity to pool uplink resources, using communication links like Bluetooth or Wi-Fi to enhance uplink performance by combining data rates and sharing resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If wireless devices transmit from greater distances from the access node, then coverage area is expanded, but uplink signal quality and data transmission reliability deteriorate
Solution Approach 1:
The patent combines multiple wireless devices into a cooperative group where devices pool their uplink transmission resources. By merging transmission capabilities of multiple devices, the system achieves improved uplink signal quality for distant devices while maintaining expanded coverage, resolving the contradiction between coverage area and signal reliability.
2Reliability
If handover procedures are implemented for devices at cell edges, then connectivity is maintained, but transmission delays and resource consumption increase
Solution Approach 1:
The patent establishes cooperative device groups in advance before handover becomes necessary. By pre-organizing devices into groups with shared uplink resources, the system eliminates the need for frequent handovers at cell edges, thereby preventing transmission delays and reducing resource consumption associated with handover procedures.
3Length of moving object
If high power transmit capability is used, then uplink transmission distance is increased, but device power consumption and hardware complexity increase
Solution Approach 1:
The patent merges the transmit capabilities of multiple devices into a cooperative transmission system. Instead of relying on a single device to transmit at high power, multiple devices in a group contribute their transmission resources, achieving extended transmission distance while distributing and reducing the power consumption burden on individual devices.
4Productivity
If multiple wireless devices share uplink resources, then uplink performance is improved, but device complexity for resource coordination increases
Solution Approach 1:
The patent introduces an intermediary coordination mechanism where a designated lead device or network controller manages resource allocation within the cooperative group. This intermediary approach enables multiple devices to share uplink resources effectively while minimizing the complexity each individual device must handle, as the coordination burden is centralized rather than distributed among all devices.
