Aggregating Multiple Wireless Receiver Signals for Downlink QoS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication networks struggle to support downlink Quality-of-Service (QoS) requirements, particularly Guaranteed Bit Rate (GBR), due to limitations in radio link quality and network capacity.
Innovation Solution
The system employs multiple wireless receivers to aggregate signals and improve downlink performance, allowing for the establishment and support of data flows with stringent QoS requirements that would otherwise be unmet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple wireless receivers are used to aggregate signals, then downlink performance is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple wireless receivers (first wireless receiver and second wireless receiver) into a unified signal aggregation system. The processors aggregate signals from both receivers to extract data, thereby improving downlink performance while managing the complexity through integrated processing architecture.
2Reliability
If data flows with stringent QoS requirements are established, then service quality is improved, but network capacity constraints are exceeded
Solution Approach 1:
The patent segments the data flow processing by dividing it into multiple parallel data radio bearers (first data radio bearer and second data radio bearer). Each bearer handles specific data flows with QoS requirements independently, allowing the system to meet stringent QoS demands while distributing the network capacity load across multiple segmented channels.
3Productivity
If signal aggregation is performed to meet GBR requirements, then throughput is improved, but processing complexity increases
Solution Approach 1:
The patent performs preliminary signal processing and aggregation at the receiver side before data extraction. The processors aggregate signals from multiple receivers and perform necessary processing in advance, enabling the system to meet GBR (Guaranteed Bit Rate) requirements and improve throughput while managing processing complexity through pre-computation and preparation.

AI summary
A method includes determining (401) information relating to each of a plurality of devices and transmitting (403) the information to cause a data flow to be requested with one or more quality-of-service requirements and the admittance of the data flow with the one or more quality-of-service requirements to be decided upon based on the information. The plurality of devices includes a first device which includes a first wireless receiver and a second device which includes a second wireless receiver. The method further comprises obtaining (405) a first signal received by the first wireless receiver over a data radio bearer associated with the data flow, obtaining (407) a second signal received by the second wireless receiver over the data radio bearer or over a further data radio bearer associated with a further data flow and extracting (409) data from the first and second signals by aggregating the first and second signals.
