Title:
LOCAL OSCILLATOR CONTROL METHOD AND SYSTEM, SIGNAL TRANSCEIVING METHOD, AND TERMINAL
Document Type and Number:
WIPO Patent Application WO/2021/121124
Kind Code:
A1
Abstract:
Provided in the present application are a local oscillator control method and system, a signal transceiving method, and a terminal. The local oscillator control method comprises: when a working resource of a scene is received and the working resource includes a millimeter wave resource, extracting a working frequency band under the scene from the working resource; evaluating whether there is interference between the working frequency band and a default frequency point of a millimeter wave intermediate frequency signal; and if there is interference, acquiring a new frequency point, matching the frequency point of an interference-free intermediate frequency signal, of a local oscillator signal, and adjusting the frequency point of the local oscillator signal from the default frequency point of the local oscillator signal to the new frequency point.
