Abstract
Embodiments of this application disclose an antenna calibration method and system. The system includes a baseband processing unit, a remote radio unit, an antenna array, and a coupled antenna. The antenna array sends a radio frequency calibration signal sent by the baseband processing unit, or receive the radio frequency calibration signal. The remote radio unit provides a plurality of transmission channels, where the plurality of transmission channels correspond to a plurality of transmission ports. The coupled antenna receives the radio frequency calibration signal sent by the baseband processing unit, and transmit a coupled signal corresponding to the radio frequency calibration signal to the baseband processing unit, or send the radio frequency calibration signal. The baseband processing unit calibrates, based on a difference between the radio frequency calibration signal and the coupled signal, a plurality of to-be-sent baseband signals corresponding to the plurality of transmission channels.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
