Chip-to-Chip Interface Power Adaptation via Channel Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power consumption in radio receivers, particularly in user equipment, is excessively high due to inefficient data transfer over chip-to-chip interfaces, which affects battery life and operational efficiency.
Innovation Solution
A communication device adapts data transmission over a chip-to-chip interface by determining the channel quality of received radio signals and adjusting the transmission parameters, such as signal-to-noise ratio or bits per sample, to match the required quality, thereby optimizing power consumption based on signal properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the chip-to-chip interface is designed to handle the worst case scenario with highest possible data rate, then the reliability is improved, but the power consumption increases unnecessarily
Solution Approach 1:
The patent applies dynamics by making the transmission parameters of the chip-to-chip interface adjustable rather than fixed. The interface adapts its data rate and channel quality settings dynamically based on the actual received signal quality, transitioning between different operational states to match requirements, thereby avoiding constant high-power operation while maintaining reliability when needed
Solution Approach 2:
The patent changes physical parameters of the transmission interface based on channel conditions. Specifically, it adjusts the data rate and channel quality parameters of the chip-to-chip transmission according to the measured quality of the received radio signal, allowing the system to operate at lower power when high data rates are not required while ensuring reliability when signal conditions demand it
2Reliability
If the transmission parameters are increased to ensure sufficient channel quality, then the reliability is improved, but the power consumption increases
Solution Approach 1:
The patent implements feedback by continuously monitoring the quality of the received radio signal and using this information to adjust the transmission parameters of the chip-to-chip interface. The system measures channel quality indicators from the received signal and feeds this information back to control the transmission settings, ensuring that power is only increased when actually needed to maintain sufficient channel quality
Solution Approach 2:
The system dynamically adjusts transmission parameters based on real-time channel conditions rather than maintaining fixed high settings. The chip-to-chip interface adapts its operational state according to the received signal quality, increasing power and data rate only when channel conditions require higher reliability, and reducing power when lower settings suffice

AI summary
A method in a communication device and a communication device (100) for adapting a transmission of data are provided. The transmission is transferred from a first chip (110) to a second chip (120) over a chip-to-chip interface (104, 304). The chip-to-chip-interface comprises a wired connection between the first chip and the second chip which is comprised in the communication device. The communication device receives (201) the radio signal (330), comprising the transmission of data from another communication device. The communication device determines (202), from the received radio signal (330), modulation and coding information, which is used for determining (203) a channel quality. Further, the communication device (100) adapts (204) the transmission of data based on the determined channel quality of the received radio signal (330) in such way that at least the determined channel quality is obtained when transferring (205) the transmission of data over the chip-to-chip interface to the second chip.
