Abstract
A base station testing system may receive one or more input signals originating from one or more transceivers of a base station. The base station testing system may form, based on the one or more input signals, one or more output signals associated with a beam direction. The base station testing system may provide a feedback signal, that is based on the one or more output signals, to a calibration component of the base station.
Claims20
A base station testing apparatus, comprising:
- a beamforming network, comprising:
- at least one input port configured to receive one or more input signals originating from one or more transceivers of a base station;
- and
- at least one output port configured to receive a signal from the at least one input port that is based on the one or more input signals, and to output, based on the signal, one or more output signals associated with a beam direction;
- a feedback component configured to provide a feedback signal, that is based on the one or more output signals, to a calibration component of the base station, and
- the calibration component configured to use the feedback signal to cause the one or more transceivers to transmit a phase-adjusted signal;
- and
- a test component configured to receive the phase-adjusted signal.

A base station testing system, comprising:
- a feedback component configured to output one or more feedback signals that are based on one or more calibration signals received from a calibration component of a base station;
- a beamforming network configured to provide one or more output signals, that are based on the one or more feedback signals and are associated with a beam direction, to the base station, wherein the beamforming network comprises:
- at least one input port configured to receive the one or more feedback signals from the feedback component, and
- at least one output port configured to receive a signal from the at least one input port that is based on the one or more feedback signals, and to output, based on the signal, the one or more output signals;
- and
- a test component configured to receive the one or more feedback signals of the feedback component.

A method, comprising:
- receiving, by a base station testing system, one or more input signals originating from one or more transceivers of a base station;
- forming, by the base station testing system and based on the one or more input signals, one or more output signals associated with a beam direction;
- and
- providing, by the base station testing system, a feedback signal, that is based on the one or more output signals to a calibration component of the base station,
- the calibration component configured to use the feedback signal to cause the one or more transceivers to transmit a phase-adjusted signal;
- and
- receiving, by a test component of the base station testing system, the phase-adjusted signal.
