LTE-advanced 8×8 MIMO measurements in an indoor scenario

The potential link performance gains obtained with up to 8×8 MIMO transmissions as standardized in 3GPP LTE Release 10 have been evaluated in an indoor measurement campaign using a testbed implementation. For well-separated antennas, the results show increasing downlink throughput when increasing the number of transmit and receive antennas, up to a median throughput of 335 Mbps for an 8×8 MIMO configuration on a 20 MHz carrier. A similar and only slightly smaller throughput is achieved when using a compact UE array of a size that is more reasonable for a consumer device implementation.
