Wireless Terminal Signal Timing Randomization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile communication terminals generate periodic signals that cause noise interference with voice signals in wired or wireless telephony, particularly due to their frequency alignment with voice frequency bands, leading to significant noise issues during voice communication.
Innovation Solution
A method and apparatus for randomizing the transmission timing of periodic signals from mobile communication terminals, using configuration information received from a base station to determine and adjust the transmission timing, thereby breaking the periodicity and reducing noise interference with voice signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If periodic signal transmission is used for channel measurement information, then transmission efficiency is improved, but noise interference with voice signals occurs
Solution Approach 1:
The patent applies dynamics by making the signal transmission timing variable rather than fixed. The terminal determines transmission timing dynamically using a random variable k that changes with each transmission, transforming the static periodic transmission into a dynamic aperiodic transmission pattern that avoids fixed frequency interference with voice signals
Solution Approach 2:
The patent changes the timing parameter of signal transmission from a fixed periodic interval to a randomized interval. By introducing randomness in the transmission timing parameter through the variable k and offset value, the signal no longer transmits at regular intervals, thereby eliminating the frequency components that cause noise interference with voice bands
2Ease of operation
If signal transmission timing is fixed periodically, then transmission timing is simple to determine, but frequency interference with voice band occurs
Solution Approach 1:
The patent applies preliminary action by pre-configuring the offset value and random variable k before signal transmission. The base station provides configuration information including the offset value in advance, and the terminal pre-determines the random variable k based on this configuration, so that when signal transmission is needed, the timing can be quickly determined without complex real-time calculations
Solution Approach 2:
The terminal autonomously determines its own signal transmission timing by using the pre-configured offset value and generating the random variable k itself based on this configuration. The system serves itself by enabling the terminal to independently calculate transmission timing without requiring complex coordination with the base station for each transmission instance
