Antenna Selection via Single Transceiver Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication devices with multiple antennas and transceiver units increase manufacturing costs while aiming to enhance communication quality, as they require multiple transceiver units to form multiple communication paths.
Innovation Solution
A communication device with a switch element and an antenna selection and control module that switches between two antennas, measuring communication quality parameters during busy and idle periods to determine the best antenna for operation, allowing a single transceiver to be shared between them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple transceiver units are used to form multiple communication paths, then communication quality is improved, but manufacturing cost increases
Solution Approach 1:
Multiple antennas share a single transceiver unit through a switching mechanism. The switch element dynamically connects the transceiver to different antennas based on signal quality measurements, combining the functionality of multiple transceiver units into one while maintaining multiple communication paths through antenna diversity
Solution Approach 2:
A single transceiver unit performs multiple functions by sequentially connecting to different antennas. The transceiver serves as a universal communication interface that can operate with any of the multiple antennas, adapting its function based on the current best antenna selection
2Ease of manufacture
If a single transceiver is shared between multiple antennas, then manufacturing cost is reduced, but antenna selection complexity increases
Solution Approach 1:
The system performs preliminary measurements of signal quality parameters for each antenna before making a selection decision. The antenna selection module pre-evaluates communication quality metrics during idle periods or using reference signals, so that when switching is needed, the decision is based on advance information rather than real-time complexity
Solution Approach 2:
The system continuously monitors signal quality parameters and provides feedback to the antenna selection module. This feedback mechanism enables dynamic adaptation where the transceiver measures communication quality, reports back to the selector, and triggers switching only when improvement is detected, reducing unnecessary switching complexity

AI summary
The invention provides a communication device and a communication method. The communication device with at least a first antenna and a second antenna includes a switch element, a transceiver, and an antenna selection and control module. The switch element is coupled to the first antenna and the second antenna. The transceiver is coupled to the switch element. The antenna selection and control module controls the switch element to switch between the first antenna and the second antenna, such that the first antenna and the second antenna are respectively set as an operating antenna and a non-operating antenna. In one or more busy time periods of the operating antenna, the transceiver measures a first communication quality parameter of the operating antenna. In one or more idle time periods of the operating antenna, the transceiver measures a second communication quality parameter of the non-operating antenna.
