Solution Overview
Problem
Current 5G NR wireless communication devices face challenges in simplifying RF architecture, reducing path loss, and optimizing performance due to complex antenna switching schemes, which increase power consumption and cost.
Innovation Solution
A multiway switch with 10 throw (T) ports and 4 pole (P) ports is integrated with the radio frequency circuit and antenna system, enabling dual-frequency dual-transmit mode operation by selectively coupling T ports with P ports to transmit sounding reference signals through four antennas, reducing the number of switches and improving transmission efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional antenna switching schemes are used in 5G NR wireless communication devices, then the device can support multiple antennas and frequency bands, but the RF architecture becomes complex, increasing power consumption and cost
Solution Approach 1:
The patent combines multiple switching functions into a single multiway switch device that integrates both transmit and receive path switching capabilities. This consolidation reduces the number of separate switching components needed in the RF architecture, thereby simplifying the overall system while maintaining support for multiple antennas and frequency bands.
Solution Approach 2:
The multiway switch is designed to perform multiple functions simultaneously: it handles transmit path switching, receive path switching, and supports multiple frequency bands all within a single device. This multi-functionality eliminates the need for separate switching components for each function, reducing RF architecture complexity while preserving adaptability.
2Productivity
If multiple switches are used in the RF architecture to support dual-frequency dual-transmit mode, then the device can transmit sounding reference signals through multiple antennas, but the number of switches increases, leading to higher power consumption and cost
Solution Approach 1:
The patent merges multiple switching operations into a single multiway switch that can handle transmit and receive paths for multiple antennas simultaneously. By consolidating what would traditionally require multiple separate switches into one device, the system reduces the total number of active switching components, thereby lowering power consumption while maintaining high data transmission rates through efficient signal routing.
3Adaptability or versatility
If traditional antenna switching schemes are used, then the device can support four-antenna RF system architecture, but path loss increases due to the complexity of signal routing through multiple switches
Solution Approach 1:
The patent consolidates multiple switching functions into a single multiway switch, creating more direct signal paths between antennas and the RF circuit. This reduction in the number of switching stages minimizes the accumulation of insertion losses that occur when signals pass through multiple separate switches, thereby reducing overall path loss while maintaining four-antenna system capability.

AI summary
A multiway switch, a radio frequency system, and a wireless communication device are provided. The multiway switch includes ten T ports and four P ports, the ten T ports include two first T ports, each of which the two first T ports is coupled with all of the four P ports. The multiway switch is configured to be coupled with a radio frequency circuit of a wireless communication device through the ten T ports and an antenna system of the wireless communication device through the four P ports, to implement a preset function of the wireless communication device, the antenna system comprising four antennas corresponding to the four P ports, and the preset function being a function of transmitting a sounding reference signal (SRS) through the four antennas in turn.
