[srslte-users] Error - MIMO configurations for Max throughput

[Bilal Maqsood]

Hi All,

I hope all is well.

I was trying to set MIMO configurations TM3/TM4 for max throughput test. I
am using one USRP X310 as UE and one as eNB. At UE side I changed nof_rx_ant
= 2 and at the enb side I changed tm = 3 and nof_ports = 2.

For n_prb = 75 or 100, UE cannot detect the eNB. I have tried different
gain settings but of no use.

For n_prb = 50, UE can detect the eNB but I get the following displayed on
the console
Number of ports and layers must be 1 for transmission on single antenna
ports (2, 1).

The console trace is given below.

Please, let me know what could be the problem. Many thanks.

Regards,
Bilal
