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>
Current Reference Signal Received Power (RSRP) level at the time of report. Numerical range in dBm.
255 – Not known or not detectable.
<CINR>
Current CINR level at the time of report. Numerical range in dBm.
127 – Not known or not detectable.

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
