A-IoT Antenna Selection for Concurrent Link Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in efficiently managing concurrent communications with both network devices and power-limited devices in ambient IoT (A-IoT) systems, particularly due to the need for quick antenna switching and potential degradation of communication quality.
Innovation Solution
A terminal device determines whether a communication link with a network device can switch to a different antenna, identifying a set of available antennas for A-IoT communication based on this determination, allowing concurrent communication with power-limited devices without degrading the RRC connection quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the terminal device uses the same antenna for both network device communication and A-IoT communication, then device complexity is reduced, but communication quality degrades due to antenna switching requirements
Solution Approach 1:
The patent segments the antenna resources by identifying a dedicated first antenna for network device communication and a separate set of antennas (second antenna or other antennas) for A-IoT communication. This segmentation eliminates the need for antenna switching and allows concurrent communications without interference, resolving the contradiction between device complexity and communication quality.
2Productivity
If the terminal device switches antennas quickly to support A-IoT communication, then productivity is improved, but communication quality degrades due to switching interruptions
Solution Approach 1:
The patent performs preliminary action by pre-identifying and reserving a dedicated first antenna for network device communication before A-IoT communication begins. This advance preparation ensures that the network communication antenna is already secured and does not need to be switched during concurrent operations, maintaining RRC connection quality while enabling concurrent A-IoT communication.
3Reliability
If the terminal device allocates separate antennas for network and A-IoT communications, then communication quality is maintained, but device complexity increases
Solution Approach 1:
The patent applies universality by enabling the terminal device to dynamically determine and allocate antennas based on communication needs. The same antenna set can serve different purposes (network communication or A-IoT communication) depending on the determination result, reducing the need for permanently dedicated hardware while maintaining communication quality through intelligent resource allocation.

AI summary
Example embodiments of the present disclosure relate to a terminal device, a method, an apparatus and a computer readable storage medium for determination of antennas for an A-IoT communication. In the solution, a terminal device may determine whether a communication link with a network device is capable of switching from a first antenna to a different antenna, and further determine a set of antennas available for a communication with a power-limited device based on a determination result for the communication link with the network device. Specifically, the terminal device may determine whether the first antenna which is used for a communication link with a network device can be included into the set of antennas available for a communication with a power-limited device. As a result, a communication with the network device and a communication with the power-limited device can be concurrently performed by the terminal device.
