An antenna switching circuit, electronic device and method. The switching circuit includes a radio frequency processor, a radio frequency front-end, a first switch, and an antenna system with a plurality of antennas. The radio frequency processor receives a first radio frequency signal, generates a second radio frequency signal based on a loss value of the first switch, and transmits the second radio frequency signal to the first switch. The first switch selects, from a plurality of radio frequency channels in the radio frequency front-end, a radio frequency channel coupled with the radio frequency processor, and transmits the second radio frequency signal to a radio frequency channel. The radio frequency front-end receives and processes the second radio frequency signal to generate a third radio frequency signal and transmits it to the antenna system, which outputs the third radio frequency signal.

One example method includes a base station obtains, in real time, a network access request message from a terminal, where the network access request message includes at least one of a network standard supported by the terminal, an access service of the terminal, or QoS of the access service, the base station dynamically allocates spectrum resources to different network standards based on the network access request message, and the base station sends a first network standard access indication message to the terminal, where the terminal accesses a service based on the first network standard access indication message via a corresponding network standard.

Dynamic spectrum resource allocation for full spectrum sharing

For a terminal located in any area of a first cell in a first system, a sum of actual interference of all second cells to any spectrum resource to be used by the terminal can be determined according to a pre-established interference matrix for representing historical reference interference of each second cell in a second system to each area in the first cell and a spectrum resource real-time occupation status of each second cell; when it is determined that the sum does not exceed a preset interference threshold value range, it is determined that the terminal can use the any spectrum resource; or when it is determined that the sum exceeds a preset interference threshold value range, it is determined that the terminal cannot use the any spectrum resource.
