Uplink Control Channel Coding for Mixed-Priority UCI Multiplexing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in appropriately executing channel coding for uplink control information (UCI) with different priorities multiplexed on uplink control channels, particularly in high-frequency bands of 5G and beyond.
Innovation Solution
A terminal is equipped with a control unit that multiplexes uplink control information with different priorities using a new scaling factor for channel coding, determining the number of resource blocks based on the effective code rate of each UCI, and transmitting the signal through an uplink control channel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If uplink control information with different priorities is multiplexed on uplink control channel, then resource utilization is improved, but channel coding performance deteriorates
Solution Approach 1:
The patent segments the uplink control information into different priority levels (first priority and second priority UCIs) and applies separate channel coding processes to each segment. This allows optimized coding parameters for each priority level, resolving the contradiction by maintaining high resource utilization while ensuring reliable coding performance for critical information.
Solution Approach 2:
The patent applies different channel coding parameters (such as code rates and modulation schemes) to different priority levels of UCI. High-priority UCIs receive more robust coding parameters while low-priority UCIs use efficient parameters, achieving local optimization that balances resource utilization with coding reliability.
2Manufacturing precision
If separate coding is performed for different priority UCIs, then channel coding accuracy is improved, but processing complexity increases
Solution Approach 1:
The patent performs preliminary classification of UCIs into priority levels before channel coding. By pre-sorting and identifying which UCIs require separate coding based on their priority, the system achieves accurate coding without excessive complexity in the actual coding process.

AI summary
A terminal comprises: a control unit that multiplexes two or more uplink control information having mutually different priorities on an uplink control channel; and a communication unit that transmits an uplink signal using the uplink control channel on which the two or more uplink control information are multiplexed; wherein the control unit determines a number of resource blocks related to the uplink control channel in a separate coding of the two or more uplink control information.
