RF Channel Segmentation for Lower-Power Multi-Antenna Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high power consumption of multi-antenna radio frequency modules in communication systems is a challenge, particularly when improving user capacity and experience, as existing methods like symbol or channel shutdown have limitations.
Innovation Solution
Decouple radio frequency channels into two sets based on signal type, where one set carries cell-level common signals and the other carries user-level signals, allowing selective activation and deactivation of channels based on load and signal quality to reduce power consumption.

Engineering Contradiction Analysis
1Productivity
If multi-antenna technology is used to improve user capacity and experience, then user capacity and experience are improved, but power consumption of radio frequency module increases
Solution Approach 1:
The patent segments radio frequency channels into two distinct sets: a first set for carrying cell-level common signals and a second set for carrying user-level signals. This segmentation allows independent control and optimization of each channel set, enabling the system to maintain basic coverage functions while reducing power consumption by selectively activating only necessary channels based on load conditions.
2Reliability
If all radio frequency channels are activated to ensure basic coverage, then coverage is maintained, but power consumption increases
Solution Approach 1:
The patent implements dynamic channel activation where the second set of radio frequency channels (carrying user-level signals) can be selectively activated or deactivated based on network load status and signal quality requirements. The first set of channels maintaining basic coverage remains active, while the second set adapts its activation state dynamically, thus reducing power consumption during low-load periods while ensuring coverage reliability when needed.
3Productivity
If user-level signals are processed to improve capacity, then network capacity increases, but interference with cell-level common signals may occur
Solution Approach 1:
By segmenting radio frequency channels into separate sets for cell-level common signals and user-level signals, the patent ensures that processing of user-level signals in the second channel set does not interfere with cell-level common signal processing in the first channel set. This physical and functional separation maintains signal independence and reliability while enabling enhanced network capacity through optimized user-level signal handling.

A communication method,-including-using a radio frequency channel in a first radio frequency channel set to carry a first-type signal, and using a radio frequency channel in a second radio frequency channel set to carry a second-type signal, where the first radio frequency channel set and the second radio frequency channel set are different, and functions of the first-type signal and the second-type signal are different.
