Terminal Higher Layer Parameter Control via DCI Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Future radio communication systems, such as 5G and New Radio (NR), face challenges in controlling the configuration and application of new Downlink Control Information (DCI) formats and higher layer parameters, which are essential for supporting diverse communication requirements like enhanced Mobile Broadband (eMBB), massive Machine-Type Communications (mMTC), and Ultra-Reliable and Low-Latency Communications (URLLC).
Innovation Solution
A terminal is designed with a receiving section to receive higher layer parameters for a grant-based uplink shared channel and a control section to determine the application of these parameters based on higher layer signaling, allowing flexible control of communication settings, including the use of new DCI formats and higher layer parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a new DCI format and higher layer parameter are supported for diverse communication requirements, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic control of higher layer parameters through DCI signaling, allowing the terminal to flexibly activate or deactivate specific parameter configurations based on current communication requirements. This enables the system to adapt to different traffic types (eMBB, mMTC, URLLC) without permanently configuring all possible parameters, thus improving adaptability while managing device complexity through on-demand activation.
Solution Approach 2:
The patent utilizes parameter changes by introducing a mechanism where higher layer parameters can be dynamically modified through DCI signaling. The terminal receives configuration information containing multiple parameter sets and selectively applies different parameter configurations based on service requirements, enabling versatile communication support without requiring the device to permanently maintain all parameter configurations simultaneously.
2Adaptability or versatility
If multiple higher layer parameters are configured for different traffic types, then adaptability is improved, but control difficulty increases
Solution Approach 1:
The patent segments the higher layer parameter configuration into multiple independent parameter sets, each optimized for specific traffic types (e.g., one set for eMBB, another for URLLC). The DCI signaling mechanism allows selective activation of specific parameter segments based on current service requirements, making control easier by avoiding the need to manage all parameters simultaneously and enabling targeted configuration adjustments.
