Super-UE Aggregation for Edge Cell Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, UEs at the edge of cell coverage areas face limitations in data transmission throughput due to restricted bandwidth, as they cannot transmit data at higher power to avoid interference with neighboring UEs.
Innovation Solution
The formation of a virtual cluster or 'super-UE' by aggregating multiple UEs, allowing them to collaborate for data transmission and thereby enhancing throughput without increasing transmit power, is proposed. This is achieved through UE aggregation, where one UE acts as an anchor and the others as secondary UEs, sharing resources and managing connections efficiently.

Engineering Contradiction Analysis
1Productivity
If UEs at the edge of cell coverage increase transmit power to improve data transmission throughput, then throughput is improved, but interference with neighboring UEs increases causing harmful effects
Solution Approach 1:
The patent combines multiple UEs into a single super-UE entity, where the UEs share transmission resources and coordinate their communications. This merging allows the group to achieve higher throughput collectively without any single UE transmitting at high power that would cause interference to neighbors.
Solution Approach 2:
The patent introduces a network node as an intermediary that coordinates resource allocation and power control for the super-UE. The network node manages the transmission parameters to ensure that the aggregated throughput is improved while maintaining acceptable interference levels for neighboring UEs.
2Object-generated harmful factors
If UEs at the edge of cell coverage use restricted bandwidth to avoid interference, then interference is reduced, but data transmission throughput is limited
Solution Approach 1:
By merging multiple UEs into a super-UE, the system can allocate bandwidth resources more efficiently across the group. The super-UE can utilize available bandwidth resources that would be restricted for individual UEs, thereby improving throughput without proportionally increasing interference from any single transmitter.
Solution Approach 2:
The patent transitions from individual UE resource allocation to group-level resource allocation in the super-UE dimension. This allows for more flexible bandwidth assignment and resource sharing that can achieve better throughput while managing interference through coordinated multi-UE transmission strategies.
3Productivity
If multiple UEs are aggregated into a super-UE to improve throughput, then data transmission throughput is enhanced, but device complexity increases due to coordination requirements
Solution Approach 1:
The network node serves as an intermediary that handles the complex coordination and resource management tasks for the super-UE. By offloading these management functions to the network infrastructure, the complexity burden on the UEs themselves is reduced, making the super-UE aggregation more practical and scalable.
Solution Approach 2:
The super-UE configuration creates a universal framework that can accommodate multiple UEs with different capabilities and requirements. This multi-functional structure allows the system to handle diverse UE types and scenarios through a unified coordination mechanism, reducing overall system complexity through standardization.
Data Source
AI summary
One embodiment described herein takes the form of a user equipment (UE). The UE includes a transceiver and a processor. The processor is configured to associate with a secondary UE for collaborative transmission of a data payload of one of the UE or the secondary UE to a base station. The processor is configured to determine a link quality with the base station or the secondary UE, and determine a location of the UE or the secondary UE while associated with the secondary UE. The processor is configured to transmit to the base station or the secondary UE at least the determined link quality or the determined location, and determine to maintain, re-establish, or disable the association with the secondary UE based on at least one of a number of factors including: the determined link quality, the determined location, or an indication received from the base station.
