Timing Determination for High-Frequency Communication Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems operating in high frequency bands, such as 57 GHz to 71 GHz, the current Subcarrier Spacing (SCS) is insufficient, leading to reduced symbol length and inadequate scheduling or feedback timing for terminal processing, which affects transmission performance.
Innovation Solution
A timing determination method that acquires information including subcarrier spacing, band information, and timing superposition domain, and determines a timing set from a first channel transmission to a second channel transmission, ensuring that scheduling or feedback timing meets terminal processing time requirements even with enlarged SCS.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the Subcarrier Spacing (SCS) is enlarged to meet high-frequency communication requirements, then the communication system can operate in high bands (57 GHz to 71 GHz), but the length of each symbol is reduced and the scheduling timing or feedback timing becomes insufficient, affecting terminal processing time and transmission performance
Solution Approach 1:
The patent applies dynamics by making the timing set configurable and adaptable rather than fixed. The timing set can be dynamically adjusted based on the enlarged SCS configuration, allowing the system to adapt timing parameters to maintain sufficient processing time while operating at higher communication speeds in high-frequency bands
Solution Approach 2:
The patent changes the timing parameter by introducing a configurable timing set that can be adjusted according to the SCS enlargement. This parameter change allows the scheduling timing and feedback timing to be reconfigured to ensure adequate terminal processing time even when symbol length is reduced due to larger SCS
2Adaptability or versatility
If the Subcarrier Spacing (SCS) is enlarged, then the communication system can support high-frequency bands, but the scheduling timing or feedback timing among different channel transmissions becomes too small to meet terminal processing requirements
Solution Approach 1:
The patent makes the timing configuration dynamic and adaptable to different high-band scenarios. The timing set can be configured based on the specific SCS values and channel transmission requirements, allowing the system to maintain reliable transmission performance while adapting to various high-frequency band conditions
Solution Approach 2:
The patent changes the timing parameter by introducing a configurable timing set that can be adjusted according to the SCS enlargement. This parameter change allows the scheduling timing and feedback timing to be reconfigured to ensure adequate terminal processing time even when symbol length is reduced due to larger SCS
