Set command

The set command subscribes Coverage Enhancement (CE) notifications and reads current parameters.

Syntax:

+CEINFO=<Reporting>

Notification syntax:

+CEINFO: <Reporting>,<CE Enabled>,<UE State>,<Downlink Repetition Factor>,<Uplink Repetition Factor>,<RSRP>,<CINR>

<UE State> is not between double quotation marks.

The set command parameters and their defined values are the following:

<reporting>
0 – Disable unsolicited notifications
1 – Enable unsolicited notifications
<CE Enabled>
0 – Serving cell does not support CE mode A/B
1 – Serving cell supports CE mode A/B
<UE State>
User Equipment (UE) state at the time of the report.
I – Idle
R – RACH
C – Connected
<Downlink Repetition Factor>
Downlink repetition factor.
If <UE state> is Idle or RACH, it is set to mpdcch-NumRepetition according to the current radio condition (i.e. RSRP) and prach-ParametersListCE-r13 in SIB2 if the access technology is LTE-M. It is set to npdcch-NumRepetitions according to the current radio condition and NPRACH-Parameters-NB-r13 in SIB2-NB if the access technology is NB-IoT.
If <UE state> is Connected, it is set to mpdcch-NumRepetition for the radio bearer if the access technology is LTE-M. It is set to npdcch-NumRepetitions for the radio bearer if the access technology is NB-IoT.
<Uplink Repetition Factor>
Uplink repetition factor.
If <UE state> is Idle, it is set to numRepetitionPerPreambleAttempt accordig to the current radio condition.
If <UE state> is RACH, it is set to numRepetitionPerPreambleAttempt selected by UE.
If <UE state> is Connected, it is set to repetition number for PUSCH if the access technology is LTE-M. It is set to repetition number for NPUSCH if the access technology is NB-IoT.
<rsrp>
0 – RSRP < −140 dBm
1 – When −140 dBm ≤ RSRP < −139 dBm
2 – When −139 dBm ≤ RSRP < −138 dBm
...
95 – When −46 dBm ≤ RSRP < −45 dBm
96 – When −45 dBm ≤ RSRP < −44 dBm
97 – When −44 dBm ≤ RSRP
255 – Not known or not detectable
<CINR>
0 – SNR < −24 dB
1 – When −24 dB ≤ SNR < −23 dB
2 – When −23 dB ≤ SNR < −22 dB
...
47 – When 22 dB ≤ SNR < 23 dB
48 – When 23 dB ≤ SNR < 24 dB
49 – When 24 dB ≤ SNR

The following command example subscribes unsolicited CE notifications:

AT+CEINFO=1
OK

The following is an example of an unsolicited CE notification:

+CEINFO: 1,1,C,5,3,-50,10
