Abstract
A method is provided for generating test data for testing radio equipment. The method includes: determining, by a test apparatus, one or more beam identifiers; selecting, by the test apparatus, based on the one or more beam identifiers, one or more radio channel models; receiving, by the test apparatus, a baseband signal representing I/Q data of one or more beamforming antennas; processing, by the test apparatus, the baseband signal representing I/Q data according to the selected radio channel model; and transmitting, by the test apparatus, the processed baseband signal representing I/Q data to a radio equipment under test.

A method of generating test data for testing radio equipment, the method comprising:
- determining, by a test apparatus, one or more beam identifiers;
- selecting, by the test apparatus, one or more radio channel models based on the one or more beam identifiers, wherein the test apparatus positioned between a radio unit and a distributed unit reads a fronthaul communication and selects the one or more radio channel models based on the one or more beam identifiers transmitted from the distributed unit;
- receiving, by the test apparatus, a baseband signal representing In-phase and Quadrature components (I/Q) data of one or more beamforming antennas;
- processing, by the test apparatus, the baseband signal representing I/Q data according to the selected one or more radio channel models, wherein the one or more radio channel models are applied in the fronthaul communication by processing the I/Q data transmitted over the fronthaul communication between the distributed unit and the radio unit;
- and
- transmitting, by the test apparatus, the processed baseband signal representing the I/Q data to a radio equipment under test.
A test apparatus for generating test data for testing radio equipment, wherein the test apparatus is configured to:
- determine one or more beam identifiers;
- select one or more radio channel models based on the one or more beam identifiers, wherein the test apparatus, when positioned between a radio unit and a distributed unit, is configured to read a fronthaul communication and select the one or more radio channel models based on the one or more beam identifiers transmitted from the distributed unit;
- receive a baseband signal representing In-phase and Quadrature components (I/Q) data of one or more beamforming antennas;
- process the baseband signal representing I/Q data according to the selected one or more radio channel models;
- and
- transmit the processed baseband signal representing the I/Q data to a radio equipment under test.
A system comprising:
- a test apparatus;
- and
- a radio equipment configured to operate based on a machine learning model,
- wherein the test apparatus is configured to:
- determine one or more beam identifiers;
- select one or more radio channel models based on the one or more beam identifiers, wherein the test apparatus, when positioned between a radio unit and a distributed unit, is configured to read a fronthaul communication and select the one or more radio channel models based on the one or more beam identifiers transmitted from the distributed unit;
- receive a baseband signal representing In-phase and Quadrature components (I/Q) data of one or more beamforming antennas;
- process the baseband signal representing the I/Q data according to the selected one or more radio channel models;
- and
- transmit the processed baseband signal representing the I/Q data to the radio equipment, and
- wherein the processed baseband signal representing the I/Q data is configured to train the machine learning model of the radio equipment.
