Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently providing services in 5G communication systems, particularly in managing subcarrier spacing and cyclic prefix configurations to optimize slot formats and resource allocation for effective data transmission and reception.
Innovation Solution
The method involves a terminal receiving subcarrier spacing and cyclic prefix information from a base station through higher layer signaling, determining slot formats with extended cyclic prefixes based on normal cyclic prefixes, and mapping link information across consecutive symbols to optimize data transmission and reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If extended cyclic prefix is used in 5G communication systems, then transmission reliability is improved by reducing stray electric waves and increasing transmission distance, but system complexity increases due to dynamic slot format adjustment requirements
Solution Approach 1:
The patent implements dynamic slot format adjustment based on cyclic prefix type. When extended cyclic prefix is detected, the system automatically adjusts slot formats and resource allocation patterns to match the extended timing requirements, enabling adaptive optimization without manual reconfiguration
Solution Approach 2:
The system changes operational parameters (slot format, resource allocation) based on the cyclic prefix configuration. By detecting the CP type and dynamically adjusting related parameters, the system resolves the contradiction between reliability improvement and complexity increase
2Productivity
If slot formats are dynamically adjusted for extended cyclic prefix, then data transmission efficiency is improved, but processing complexity increases
Solution Approach 1:
The base station performs preliminary detection of cyclic prefix type and pre-determines appropriate slot formats before data transmission begins. This advance preparation enables efficient transmission without real-time processing complexity during actual data transfer
Solution Approach 2:
The system uses the cyclic prefix type itself as the basis for automatic slot format selection. The detected CP configuration directly determines the slot structure, creating a self-adjusting mechanism that improves efficiency without requiring external control or complex processing
