Metrics are generated once per second by default. This can be configured using the expert.metrics_period_secs parameter in ue.conf
.
Metrics are provided for the received signal (Signal), downlink (DL) and uplink (UL) respectively. The following metrics are provided:
- cc
Component carrier
- rsrp
- pl
Pathloss (dB)
- cfo
- mcs
Modulation and coding scheme (0-28)
- snr
- turbo
Average number of turbo decoder iterations
- brate
Bitrate (bits/sec)
- bler
Block error rate
- ta_us
Timing advance (uS)
- buff
Uplink buffer status - data waiting to be transmitted (bytes)
