Abstract
A method of testing radio equipment is disclosed herein. The method includes: receiving, by way of a radio channel test apparatus, a baseband signal representing I/Q data of one or more radio channels; processing, by way of the radio channel test apparatus, the baseband signal representing I/Q data according to one or more radio channel models; and transmitting, by way of the radio channel test apparatus, the processed baseband data representing I/Q data to a radio equipment under test.
Claims22
A method of testing radio equipment, the method comprising:
- receiving, by way of a radio channel test apparatus, baseband data representing in-phase and quadrature components (I/Q) data of one or more radio channels via a first section of a fronthaul communication link;
- processing, by way of the radio channel test apparatus, the baseband data representing I/Q data received via the first section of the fronthaul communication link according to a downlink channel model of a first radio channel;
- transmitting, by way of the radio channel test apparatus, the processed baseband data representing I/Q data to a radio equipment under test data via a second section of the fronthaul communication link;
- receiving, by the radio channel test apparatus, baseband data via the second section of the fronthaul communication link;
- processing, by the radio channel test apparatus, the baseband data received via the second section of the fronthaul communication link according to an uplink channel model of the first radio channel;
- and
- transmitting, by the radio channel test apparatus, the processed baseband data via the first section of the fronthaul communication link.
