Reply To: low RI with 2x2CLSM


Dear Nasser,

about the rank, this is correct. Only for very good channel conditions, there will be an improvement when using two streams in a 2×2 setup.

Why you see the increase in throughput comes from a higher SINR when using the transmit and receive antennas for diversity.

You can also check this by looking at the average CQI. It will be significantly higher for a 2×2 setup than for a 1×1 setup.

Best regards,
