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.1
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.1 Numerical range in dBm.
255 – Not known or not detectable.
<CINR>
Current CINR level at the time of report1. 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
Parent topic: Coverage enhancement mode information +CEINFO
1 The value corresponds to the last value that has been stored before the time of report. For example, when releasing an RRC connection, the transition from connection to idle state and the next <UE State> being stored and reported can take several seconds.
