Uplink Control Information Transmission via Service-Specific PUSCH Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for transmitting uplink control information (UCI) in wireless communication technologies fail to meet the different reliability requirements of Ultra Reliable Low Latency Communication (URLLC) and Enhance Mobile Broadband (eMBB) services, as they use the same UCI piggyback rules for both services.
Innovation Solution
The method involves configuring different Physical Uplink Shared Channel (PUSCH) parameters for different types of UCI, allowing the terminal to transmit UCI based on specific PUSCH configuration parameters that match the reliability requirements of each service type, including setting state parameters, scaling parameters, and beta-offsets to manage Resource Elements (REs) and code rate adjustments.

Engineering Contradiction Analysis
1Reliability
If the same UCI piggyback rules are used for both URLLC and eMBB services, then the device complexity is reduced, but the reliability requirement of URLLC service cannot be met
Solution Approach 1:
The patent applies local quality by configuring different PUSCH parameters (such as beta-offset, scaling factor, and resource element allocation) specifically for URLLC service UCI transmissions. This allows the system to provide enhanced reliability for critical URLLC control information while maintaining simpler configuration for eMBB service, thus resolving the contradiction between reliability requirements and device complexity.
2Reliability
If different PUSCH configuration parameters are configured for different service types, then the reliability requirement of URLLC service is met, but the device complexity increases
Solution Approach 1:
The patent segments the PUSCH configuration into service-type-specific parameters, allowing independent optimization for URLLC and eMBB services. By dividing the configuration into distinct segments (URLLC-specific parameters vs. eMBB parameters), the system can meet the high reliability requirements of URLLC without unnecessarily complicating the entire UCI transmission system.
3Reliability
If UCI is transmitted on PUSCH with standard piggyback rules, then the ease of operation is maintained, but the loss of information occurs for URLLC service
Solution Approach 1:
The patent changes key transmission parameters (beta-offset value, scaling factor, resource element mapping) when transmitting UCI for URLLC service on PUSCH. These parameter modifications ensure that critical URLLC control information receives enhanced protection and prioritization, preventing information loss while maintaining the overall simplicity of the piggyback transmission mechanism.
