Power Control Group Boundary Determination for Wireless Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems with multiple antenna elements face interference issues due to signals propagating along different paths, leading to destructive interference, which affects spectral efficiency and signal quality.
Innovation Solution
A method is introduced to determine a power control group boundary by receiving samples, setting a window, determining the number of power control bits within the window, and moving the window to identify the point with the largest number of power control bits, allowing for modification of signals based on a time boundary to improve signal quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple antenna elements are used to transmit signals, then spectral efficiency is improved, but signal interference increases due to different propagation paths
Solution Approach 1:
The patent changes the timing parameters of signal transmission by determining optimal power control group boundaries and applying signal modifications at specific time points within these groups. This temporal parameter adjustment helps synchronize signals from multiple antenna elements, reducing interference while maintaining spectral efficiency
Solution Approach 2:
The patent performs preliminary determination of power control group boundaries and calculates optimal signal modification timing before actual signal transmission. This advance preparation allows the system to pre-coordinate signals from multiple antenna elements, preventing interference rather than correcting it after occurrence
2Reliability
If signal modifications are applied frequently to improve quality, then signal quality improves, but synchronization accuracy may deteriorate
Solution Approach 1:
The patent implements periodic signal modifications structured around power control groups, which are time-bound intervals. By confining modifications to specific periodic windows rather than applying them continuously or at arbitrary intervals, the system maintains both signal quality improvement and synchronization accuracy
Solution Approach 2:
The patent dynamically determines the optimal timing within each power control group for applying signal modifications, rather than using fixed periodic intervals. This dynamic adjustment within structured time boundaries allows the system to adapt to varying channel conditions while maintaining synchronization

AI summary
Determining a power control group boundary includes receiving a plurality of samples having power control groups, where each power control group corresponds to a time period. The following are repeated for a predetermined number of iterations: a window is set at a point of a sample; a number of power control bits within the window at the point is determined; and the window is moved to a point of a next sample. A point at which the window has the largest number of power control bits is identified. A power control group boundary is determined in accordance with the window at the identified point.
