LTE-Advanced 8x8 MIMO Measurements in an Indoor Scenario
The potential link performance gain obtained with up to 8x8 MIMO transmission as standardized in 3GPP LTE Release 10 have been evaluated in an indoor measurement campaign using a testbed implementation. For well-separated antennas, the result show increasing downlink throughput when increasing the number of transmit and receive antennas, up to a median throughput of 335 Mbps for an 8x8 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.
