[srslte-users] Problem with 15 and 20 MHz bandwidth and MIMO

[Kartik Seth]

Hello,

I got srsenb working with nextepc by refering
http://nextepc.org/docs/tutorial/1-your_first_lte/
The initial setup was unreliable and then after someone mentioned on list
to set log=none, the setup started working with some reliability. Now I am
facing mainly three issues:

1. The setup works with USRP B210 till a Bandwidth of 10 MHz. For 15 and 20
MHz, mobile phone is not able to search the network. There was some mention
of adjusting power setting in sib1/sib2. Can anyone point to a working
configuration?

2. When I set nof_ports=2 and tm=3 or 4 for MIMO, the leds in B210 blink
for a second and then there is no transmission but srsenb is running in
terminal without any error. What am I missing in this setup?

3. With bladerf, there is always same error of 'Overrun detected in
scheduled RX. Some valid samples were read'. Tried with 3 different
bladerf. Any comment on this issue?

Thanks
Kartik
