Network Efficiency Node Optimizing Data Transport Unit Size
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless networks face challenges in accurately determining maximal data throughput due to inconsistencies in channel quality reporting by User Equipment (UE) from different vendors and incomplete information about the network environment, leading to suboptimal data transmission.
Innovation Solution
A method and node in a wireless communications network that retrieves UE configuration data, overrides the reported channel capability, and adjusts data transport unit sizes based on selected channel capabilities to enhance data throughput, using indicators like RSRP, HARQ feedback, CQI, and RI, while coordinating with neighboring cell transmission power reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If UE determines channel quality based on its own measurements and reports CSI, then the network can adapt data transmission, but the determination of maximal data throughput is not accurate due to UE interpretation room and vendor differences
Solution Approach 1:
The patent introduces a network side entity (e.g., base station or network controller) as an intermediary that centrally determines the transport block size. This intermediary uses both the UE-reported CSI and additional network-side information (such as interference measurements, scheduling decisions, and overall network conditions) to make the final determination, thereby mediating between UE capability reporting and actual throughput optimization while improving accuracy.
Solution Approach 2:
The patent implements a feedback mechanism where the network entity determines the transport block size based on UE CSI reports and network conditions, then schedules transmissions accordingly. The UE receives feedback through scheduling decisions and HARQ acknowledgments, allowing the system to iteratively refine throughput determination accuracy by combining UE measurements with network-side validation and adjustment.
2Loss of information
If UE reports CSI as historical data, then the network can use it for transmission adaptation, but the UE may not have complete information about the network environment
Solution Approach 1:
The patent merges UE-reported CSI information with network-side measured information (such as interference levels, scheduling status, and overall channel conditions) to create a more comprehensive basis for determining transport block size. This combination of multiple information sources compensates for the incomplete network environment information that the UE alone cannot provide.
Solution Approach 2:
The patent segments the channel quality determination process into two parts: UE-side measurement and reporting of local channel conditions, and network-side determination that incorporates both UE reports and broader network context. This segmentation allows each entity to contribute its available information while the final decision is made with complete information availability.
3Adaptability or versatility
If different UE's determine channel quality differently based on similar CQI, then vendor flexibility is allowed, but consistent throughput optimization across the network is compromised
Solution Approach 1:
Instead of allowing each UE to independently determine transport block size based on its own channel quality assessment (which leads to inconsistency), the patent inverts the approach by having the network entity determine the transport block size. This centralizes the decision-making authority, ensuring consistent throughput optimization across different UE vendors while still allowing UE implementation flexibility in reporting their capabilities.
4Ease of manufacture
If the network uses standard CSI reporting procedures, then implementation is straightforward, but the maximal data throughput cannot be fully achieved due to accuracy limitations
Solution Approach 1:
The patent performs preliminary determination of the transport block size by the network entity before actual data transmission, using both UE CSI reports and network-side information. This preliminary action allows the system to optimize throughput parameters in advance, achieving higher data throughput while maintaining implementation simplicity by integrating the determination step into the existing scheduling framework.
Data Source
AI summary
A method, computer program and a network efficiency node in a wireless communications network for enabling increased data throughput to a UE, the method comprising: retrieving information of UE configuration data, receiving an indicator of a first channel capability from the UE, determining a first data transport unit size based on the received indicator of the first channel capability, selecting a second channel capability different than the received indicated first channel capability and limited based on the information of the UE configuration data, determining a second data transport unit size based on the selected second channel capability, and transmitting scheduling information to the UE to use the second data transport unit size, thereby enabling increased data throughput.
