Abstract:
A method, an apparatus for acquiring for acquiring radio channel environment information, and a radio network control device are provided in embodiments of the present invention. The apparatus includes: an acquiring unit, configured to acquire a radio signal transmitted by a terminal; a channel information acquiring unit, configured to acquire pilot information from the radio signal, and calculate channel information according to the pilot information; and a storage unit, configured to record the channel information. With the method, the apparatus for acquiring radio channel environment information, and the radio network control device provided in the embodiments of the present invention, the real condition of the radio channel can be reflected accurately, and the exception to the user terminal or the network can be identified accurately, thereby improving the efficiency of exception handling.
Abstract:
An optical communication apparatus may include a frequency locking module and a signal light generation module. The frequency locking module is configured to: generate a target wavelength control signal based on an optical frequency difference indication signal and send the target wavelength control signal to the signal light generation module. The frequency locking module is further configured to generate a target electrical modulation signal based on a target optical frequency difference, a target electrical frequency difference, and to-be-transmitted bit information that are determined by using the optical frequency difference indication signal. The signal light generation module is configured to: generate third signal light based on the target wavelength control signal and the target electrical modulation signal and send the third signal light to a second optical communication apparatus.
