LTE UE Connection Status

This page documents the enb uepool chans command, as of r7293.
- RNTI - RNTI (radio layer connection ID) of this connection.
- If this number is followed by R, it means the connection is marked for release but not yet fully released.
- If this number is followed by S, that means it is a simulated UE generated internally by the eNodeB.
- AVGRSSI - Recent average PUSCH UL RSSI, referenced to a ideal level of 0 dB.
- CURRSSI - RSSI of most recent PUSCH UL transmission, referenced to a ideal level of 0 dB.
- UL-SNR - Short-term average PUSCH UL signal to noise ratio in dB, which should be 12 or higher for a good connection.
- UL-FER - Short-term UL transport block error rate ("frame error rate"), before counting effects of HARQ retries.
- UL-HFER - Long-term UL transport block error rate, including effects of HARQ retransmission and recovery.
- UL-eff - UL PHY efficiency in bits per resource element x100.
- 64QAM - True if 64-QAM is enabled for UL.
- ULbytes - Total number of bytes transferred on UL at the MAC layer, including padding bytes.
- DL-eff - DL PHY efficiency in bits per resource element x100.
- 256QAM - True if 256-QAM is enabled for DL.
- DLbytes - Total number of DL bytes transferred in the MAC layer on this connection.
- DL-NACK - Short-term average HARQ NACK rate for DL. An estimate of DL frame error rate at the UE.
- UC-RSSI - PUCCH RSSI in dB, on same scale as PUSCH. PUCCH is normally 6 to 20 dB lower than PUSCH.
- UC-SNR - PUCCH post-despread signal to noise ratio in dB, which should be 6 or higher for a good connection.
- UC-miss - Fraction of time when PUCCH expected to receive HARQ ACK/NACK or CSI but could not decode anything.
- Shows reliability of PUCCH, with zero being ideal.
- CQI - Fraction of time that CQI was received correctly on PUCCH.
- Age - Age of the connection in seconds.
- Idle - Idle time of the connection in seconds.
- RSRP - DL RSSI of reference signals at the UE, in dBm. See Wikipedia RSRP. For a Lab Kit, -70 to -90 is normal, less than < -90 is weak.
- RSRQ - DL channel quality at the UE. 0 is perfect, -1 .. -3 is good, less than -5 is poor. This number is a good predictor of DL throughput for this UE.
- UL-BSR - Estimated number of bytes waiting for UL transmission in the UE.
- DL-BSR - Number of bytes waiting for DL transmission in the eNodeB.
