Set command

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 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
