Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in maintaining power consistency and phase continuity during transmissions, particularly for devices with varying capabilities and usage expectations, which affects channel estimation and overall communication efficiency.
Innovation Solution
The implementation of time domain windows (TDWs) for transmissions, which are configured to maintain power consistency and phase continuity by grouping transmissions into consecutive or non-consecutive slots, allowing for joint channel estimation and DM-RS bundling, with mechanisms for handling events that disrupt continuity.

Engineering Contradiction Analysis
1Productivity
If transmissions are performed over a period of time to improve productivity, then communication efficiency is improved, but power consistency and phase continuity are compromised
Solution Approach 1:
The transmission time period is segmented into multiple time domain windows, where each window is configured to maintain power consistency and phase continuity. This segmentation allows the system to achieve both extended transmission duration (improved productivity) and maintained signal stability (improved stability) by processing transmissions in controlled segments rather than as a single continuous block.
Solution Approach 2:
The system dynamically determines the number and timing of time domain windows based on the total transmission time and requirements for power consistency and phase continuity. This dynamic adjustment allows the system to adapt transmission parameters in real-time, maintaining signal stability while optimizing communication efficiency for varying transmission durations.
2Measurement precision
If time domain windows are introduced to maintain power consistency and phase continuity, then channel estimation is improved, but device complexity increases
Solution Approach 1:
The system pre-determines the number and timing of time domain windows based on configured parameters before transmissions occur. This preliminary configuration allows the device to maintain simplified transmission logic while achieving accurate channel estimation, as the window structure is established in advance rather than requiring complex real-time calculations.
Solution Approach 2:
The system adjusts transmission parameters (such as the number of windows and their timing) based on configured values rather than requiring complex adaptive algorithms. This parameter-based approach maintains channel estimation accuracy while minimizing device complexity by using straightforward parameter modification rather than complex signal processing.
3Measurement precision
If transmissions are grouped into consecutive slots for joint channel estimation, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The transmission timeline is divided into multiple time domain windows that can be arranged in consecutive slots. This segmentation enables joint channel estimation across multiple transmission opportunities while maintaining flexible timing arrangements that minimize overall transmission time, as the windows can be configured to start immediately after previous transmissions complete without requiring excessive gaps.
