[srslte-users] when eNB use tm=1, how to know which channel/antenna eNB is using?

[Jane Zhang]

Dear srsLTE team
I implement eNB with LimeSDR. In enb.conf, I didnt set tm. It means eNB is
using tm =1(default, single antenna) . But there are two TX channels (one
channel has two ports/antenna)  and two RX channels (one channel has three
ports) on LimeSDR.

For example, I use earfcn =1934, when running eNB, it said:
Rx antenna set to LNAL
Tx antenna set to BAND1
but LNAL can be used by RX1_L(channel 1) and RX2_L (channel 2). BAND1 can
be used in TX1-1(channel 1) and TX2-1 (channel 2)

How can I know which antenna TX is using and which antenna RX is using by
the eNB?


Thank you for your help!
