Engineering Contradiction Analysis
1Productivity
If traditional uplink channel transmission methods are used in heterogeneous networks, then device compatibility is maintained, but communication efficiency and resource utilization deteriorate
Solution Approach 1:
The patent segments the uplink channel into multiple resource sets based on device capabilities and network conditions. Different resource sets are configured for different device types (e.g., first resource sets for first devices, second resource sets for second devices), allowing efficient resource allocation while maintaining manageable complexity through structured division.
Solution Approach 2:
The patent implements dynamic resource allocation where the network can switch between different resource sets based on real-time conditions. The gNodeB can dynamically determine which resource set to use for a particular device based on capability reporting and network state, optimizing communication efficiency without requiring complex static configurations.
2Quantity of substance
If device-specific resource allocation is implemented, then resource utilization improves, but system complexity increases
Solution Approach 1:
The patent creates universal resource set configurations that can serve multiple device types within categories. The resource sets are designed to be broadly applicable (e.g., first resource sets for all first devices, second resource sets for all second devices), allowing efficient resource utilization across different devices while avoiding the complexity of entirely separate configurations for each device type.
Solution Approach 2:
The patent utilizes parameter changes to adapt resource allocation to different device capabilities. Instead of creating entirely different resource configurations for each device type, the system modifies parameters (such as time resources, frequency resources, or transmission parameters) within standardized resource set frameworks, achieving efficient utilization with manageable complexity.
3Productivity
If dynamic uplink channel adjustment is implemented, then communication efficiency improves, but measurement and control difficulty increases
Solution Approach 1:
The patent implements feedback mechanisms where devices report their capabilities to the network, and the network uses this feedback information to determine appropriate resource sets. The gNodeB receives capability information from UEs and uses this feedback to dynamically select the most suitable resource set, enabling efficient communication while managing measurement complexity through structured feedback protocols.
Solution Approach 2:
The patent performs preliminary configuration of multiple resource sets before actual communication begins. The network pre-configures different resource sets with appropriate parameters, and devices report their capabilities in advance, allowing the network to pre-determine the optimal resource set allocation without complex real-time measurements during active communication.

AI summary
A wireless device receives one or more radio resource control (RRC) messages comprising one or more configuration parameters. The one or more configuration parameters indicates a first sounding reference signal (SRS) resource set with a first SRS resource set identifier (ID) and a second SRS resource set with a second SRS resource set ID, wherein the first SRS resource set ID is lower than the second SRS resource set ID. A wireless device receives downlink control information (DCI) scheduling a physical uplink shared channel (PUSCH) transmission. A wireless device transmits the PUSCH transmission using the first SRS resource set based on the first SRS resource set ID being lower than the second SRS resource set ID.
