Super-UE RRC Connection for Edge Device Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, UEs at the edge of cell coverage areas face limitations in uplink data transmission due to restricted bandwidth, as they cannot transmit data at higher power levels to avoid interference with neighboring UEs.
Innovation Solution
The establishment of a super-UE radio resource control (RRC) connection, where multiple UEs collaborate to form a virtual cluster, allowing them to share resources and enhance data throughput without increasing transmit power. This is achieved through UE aggregation, where one UE acts as an anchor and others as secondary UEs, optimizing RRC connections and data transmission.

Engineering Contradiction Analysis
1Productivity
If UEs at the edge of cell coverage transmit data at higher power levels, then data throughput is improved, but interference with neighboring UEs increases
Solution Approach 1:
The patent combines multiple UEs into a single super-UE entity that shares a common RRC connection with the base station. This merging allows the UEs to collectively utilize available bandwidth resources and achieve higher aggregate throughput without any single UE needing to transmit at harmful power levels, as the load is distributed across multiple devices
2Object-generated harmful factors
If UEs at the edge of cell coverage use restricted bandwidth, then interference with neighboring UEs is reduced, but data throughput decreases
Solution Approach 1:
By merging multiple UEs into a super-UE, the system aggregates the bandwidth utilization across all member UEs. Each UE operates within acceptable power and interference limits, but collectively they achieve high throughput by utilizing different bandwidth portions and time resources, effectively bypassing the individual bandwidth restriction
Solution Approach 2:
The patent introduces a new dimension of resource allocation by enabling multiple UEs to share a common RRC connection and utilize different bandwidth parts (BWPs) and time slots. This multi-dimensional resource allocation allows the system to achieve high aggregate throughput without any single UE exceeding interference thresholds
3Productivity
If multiple individual RRC connections are established for multiple UEs, then each UE can transmit data independently, but device complexity and signaling overhead increase
Solution Approach 1:
The patent merges multiple individual RRC connections into a single shared RRC connection that serves all member UEs of the super-UE. This reduces signaling overhead and base station processing complexity while maintaining the ability to independently manage data transmission for each UE through logical separation of data radio bearers (DRBs) within the shared connection

AI summary
One embodiment described herein takes the form of a user equipment (UE), such as a phone. The UE includes a transceiver and a processor. The processor is configured to establish a first radio resource control (RRC) connection with a base station via the transceiver. The processor is configured to associate with a secondary UE for collaboration of transmission of a data payload of one of the UE or the secondary UE to the base station, and transmit a first portion of the data payload to the base station via the transceiver.
