Description

Channel simulator port dynamic multiplexing allocation method and device for multiple scenarios

Technical field

The present application relates to the field of wireless communication technology, and specifically to a multi-scenario oriented channel simulator port dynamic multiplexing and allocation method and device.

Background technique

As a signal-level simulation and verification device for wireless communication channels, the channel simulator can simulate the attenuation, delay, multipath and other channel characteristics of radio frequency signals to realize the simulation of wireless signal transmission and reception. In addition to the fidelity of channel simulation, the importance of the channel simulator The metric is the number of ports.

Due to the high requirements for RF port connection, special connectors are required for stable interconnection to reduce insertion loss. Therefore, once a port is connected to the RF port of a wireless communication device, the RF channel is bound to the wireless communication device. If the scene needs to be changed, Adding or removing equipment requires re-connection and configuration of RF cables, which is time-consuming and labor-intensive. At the same time, the number of ports of the channel simulator directly determines the number of wireless communication equipment accesses. The greater the number of ports, the more wireless transceiver nodes that can be simulated. However, as the number of ports increases, its internal radio frequency communication interconnection relationship becomes more complex. For example, an n-port simulator has an internal interconnection network of n*(n-1)=n2-n, and a 2n The internal interconnection network of the port simulator has been increased to 2n (2n-1) = 4n2-2n, the number of ports has doubled, and the complexity of the internal interconnection network is more than 4 times the original. All have brought higher requirements, and the hardware cost and solution complexity have increased accordingly. In addition, the wireless communication equipment connected during actual use is not always in working state, but the ports it occupies are difficult to release, resulting in a waste of port and internal channel computing resources. Therefore, the number of simulator ports often matches the needs of a specific working scenario, making it difficult to adapt to the requirements of multiple complex scenarios.

In related technologies, for example, Chinese patent document (CN111181690A) records a multi-channel communication and interface dynamic switching method, which completes frame synchronization operations through the hardware layer, and the timing and working mode of multi-channels can be dynamically switched through software to achieve multi-channel communication. Although it avoids redesigning hardware solutions and increases the flexibility and compatibility of communication equipment, it is not suitable for multiple complex scenarios.

No effective solutions have yet been proposed for the problems existing in related technologies.
