Uplink Multiplexing Priority Signaling for Channel Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications systems, managing overlapping uplink channels poses challenges, particularly in selecting the appropriate uplink data channel for multiplexing with uplink control channels, which can lead to resource-consuming selection processes.
Innovation Solution
A signaling mechanism is introduced that indicates priority levels for uplink data channels, allowing user equipment (UE) to select channels for multiplexing based on these priority levels, thereby simplifying the selection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE performs detailed selection processes to choose the appropriate uplink data channel for multiplexing with uplink control channels, then the reliability of channel selection is improved, but the device complexity and resource consumption increase
Solution Approach 1:
The network entity performs preliminary actions by pre-configuring priority levels for different uplink data channels and providing this priority information to the UE before the UE needs to make channel selection decisions. This allows the UE to simply select channels based on pre-provided priority information rather than performing complex real-time analysis, thus reducing device complexity while maintaining reliable selection
Solution Approach 2:
The patent introduces priority level information as an intermediary element that mediates between the network entity's scheduling decisions and the UE's channel selection process. This intermediary priority information simplifies the UE's decision-making by providing clear selection criteria, reducing the complexity of the selection process while ensuring reliable channel choice
2Measurement precision
If the UE performs comprehensive selection processes to identify the appropriate uplink data channel, then the measurement precision of channel selection is improved, but the loss of time and processing resources increases
Solution Approach 1:
The network entity provides priority level configurations to the UE in advance, allowing the UE to make precise channel selection decisions without performing time-consuming analysis. The pre-configured priority information enables the UE to quickly identify the appropriate uplink data channel for multiplexing, thus maintaining high selection precision while minimizing processing time
Solution Approach 2:
The patent extracts the complex selection logic from the UE and relocates it to the network entity, which performs the preliminary work of determining and communicating priority levels. The UE only needs to extract and apply the simple priority-based selection rule, significantly reducing its processing time while maintaining accurate channel selection
Data Source
AI summary
Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a control message that is associated with an uplink control channel and that indicates a priority level associated with an uplink data channel. The UE may multiplex uplink control information associated with the uplink control channel with data associated with the uplink data channel based on the priority level being associated with the uplink data channel. The UE may then transmit the uplink control information multiplexed with the data in the uplink data channel.
