Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in ensuring optimal quality of service (QoS) across different transmission paths, which can lead to variations in user experience despite scheduled QoS levels, as the actual QoS support varies based on network conditions and reception points.
Innovation Solution
A method and device that receive grants conferring transmission rights and quality of service (QoS) indicators for wireless communications resource blocks, allowing user devices to select data for transmission based on estimated QoS levels, thereby improving the quality of service and user experience by optimizing data transmission according to available network paths.

Engineering Contradiction Analysis
1Productivity
If data transmission is scheduled according to transmission parameters provided by base station, then transmission efficiency is improved, but actual QoS may not meet user experience requirements due to variations in network conditions and reception points
Solution Approach 1:
The patent applies preliminary action by providing QoS indicators to the wireless device in advance of data transmission. The base station determines and transmits QoS indicators for multiple reception points before the device needs to select which data to transmit. This allows the device to proactively choose data that will achieve the desired QoS based on pre-provided information about expected QoS levels for different transmission paths, rather than reacting after transmission begins.
Solution Approach 2:
The patent implements dynamics by enabling the wireless device to dynamically select which data to transmit based on current QoS conditions. The device receives QoS indicators for multiple reception points and transmission paths, then adaptively chooses to transmit data through the path that will achieve the desired QoS level. This dynamic selection allows the system to respond to varying network conditions and reception point qualities in real-time.
2Adaptability or versatility
If multiple transmission paths are available with different QoS characteristics, then transmission flexibility is improved, but device complexity increases due to need to evaluate and select among multiple paths
Solution Approach 1:
The patent uses an intermediary approach by introducing QoS indicators as a mediating information element between the base station and the wireless device. Instead of requiring the device to directly evaluate and compare complex network conditions, transmission path qualities, and reception point characteristics, the base station provides pre-processed QoS indicators that simplify the decision-making process. The device merely needs to compare these indicators to select the appropriate transmission path.
3Measurement precision
If QoS indicators are provided for each transmission path, then QoS selection accuracy is improved, but information overhead increases
Solution Approach 1:
The patent applies the extraction principle by isolating and providing only the essential QoS indicator information needed for path selection. Rather than transmitting complete detailed information about network conditions, transmission path characteristics, and reception point qualities, the base station extracts and provides only the critical QoS indicators that enable the device to make informed transmission decisions. This minimizes information overhead while maintaining sufficient accuracy for QoS-based selection.

AI summary
Methods, devices and systems are provided for incorporating a consideration of the quality of service (QoS) of different end-to-end paths in a network, or portions thereof, into the scheduling of uplink data and the selection of data by a user device for transmission to one or more target reception points in a network. The target reception points may be determined from a number of possible reception points by a scheduling entity or by a network access node, gateway or other entity in the network and provided to a user device along with one or more indications of QoS for an uplink scheduling grant.
