Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication technologies face challenges in meeting the requirements for 5G high-reliability transmission, particularly at the edge of a cell, due to difficulties in efficiently configuring parameters for low-latency and high-reliability services.
Innovation Solution
The method involves classifying configuration parameters into an information element structure, adding this structure to a radio resource control (RRC) message, and sending it to user equipment (UE), which includes a category identifier to differentiate between cell common and UE specific parameters, thereby enhancing air interface efficiency and cooperating with the physical layer for parameter configuration.

Engineering Contradiction Analysis
1Reliability
If new downlink control information (DCI) is determined at the physical layer, then high-reliability services are supported, but it is difficult to meet the requirements for 5G high-reliability transmission at the edge of a cell
Solution Approach 1:
The configuration parameter set is segmented into multiple information elements, each carrying specific configuration parameters. This segmentation allows for organized and efficient transmission of parameters needed for high-reliability services, making the configuration process more manageable and effective, particularly for 5G transmission at cell edges.
Solution Approach 2:
The base station performs preliminary configuration by classifying parameters into information elements and embedding them in RRC messages before actual data transmission. This preliminary action ensures that all necessary configuration parameters are pre-established, enabling the UE to properly handle high-reliability transmission requirements without complex real-time configuration.
2Productivity
If configuration parameters are transmitted through traditional methods, then basic services are supported, but air interface efficiency is not optimized for low-latency and high-reliability services
Solution Approach 1:
Configuration parameters are segmented into specific information elements within the RRC message structure, allowing for targeted and efficient transmission. This segmentation enables the air interface to transmit only the necessary configuration data for low-latency and high-reliability services, optimizing bandwidth utilization and reducing transmission time.
Solution Approach 2:
The patent introduces specific parameter configurations including repetition parameters for physical layer repetition, power offset information, and HARQ parameters optimized for low-latency transmission. These parameter changes enable the system to achieve enhanced air interface efficiency and meet the stringent requirements of 5G high-reliability services.

AI summary
A method for sending configuration parameters includes: classifying a configuration parameter set into an information element structure, wherein the information element structure includes at least one information element used to carry configuration parameters in the configuration parameter set; adding the information element structure to a radio resource control RRC message; when UE establishes a low-latency and high-reliability service request, sending, to the UE, the RRC message including the information element structure.
