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 first set of antennas dedicated to network device communication and a second set of antennas available for A-IoT communication. This segmentation allows simultaneous operation of both communication types without interference, resolving the contradiction between device complexity and communication quality.
Solution Approach 2:
The patent dynamically determines antenna availability by checking whether the network device communication can switch antennas before allocating antennas for A-IoT communication. This dynamic approach enables flexible resource allocation that maintains communication quality while managing device complexity.
2Reliability
If the terminal device allocates dedicated antennas for A-IoT communication, then communication quality is maintained, but device complexity increases
Solution Approach 1:
The patent implements dynamic antenna allocation where the terminal device determines whether network device communication can switch to a different antenna before allocating the first antenna for A-IoT communication. This dynamic decision-making process maintains communication quality while avoiding unnecessary increases in device complexity.
Solution Approach 2:
The patent changes the operational parameters of the communication system by introducing antenna switching capability assessment. The terminal device evaluates whether antenna switching is possible and adjusts antenna allocation accordingly, maintaining communication quality without permanently increasing device complexity.
3Adaptability or versatility
If the terminal device performs rapid antenna switching for concurrent communications, then adaptability is improved, but loss of time increases due to switching latency
Solution Approach 1:
The patent segments antenna resources into dedicated sets for different communication types, eliminating the need for rapid switching. The first set of antennas handles network device communication while the second set handles A-IoT communication, achieving concurrent communication capability without switching latency.
Solution Approach 2:
The patent performs preliminary assessment of antenna switching capability before initiating A-IoT communication. By determining in advance whether the network device communication can switch antennas, the system avoids time loss during actual communication operations, maintaining adaptability while reducing latency.

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.
