FAQ's

Is cell selection and reselection available in NB-IoT?

As in legacy LTE networks, cell selection and reselection is available in NB-IoT. Following “3GPP TS 36.304 V13.2.0, June 2016; User Equipment (UE) procedures in idle mode” and “Rohde-Schwarz in a white paper in web link: (www.rohde-schwarz.com/appnote/ 1MA266)” for the RRC_IDLE state, cell selection and re-selection is defined for both, intra frequency and inter frequency cells. Note: Inter frequency refers here to a different 180 kHz carrier, which means that even if two carriers are used in the in-band operation embedded into the same LTE carrier, this is still referred to as an inter-frequency re-selection.

How is initial cell selection executed in NB-IoT?

For initial cell selection UE first measures the received power and quality of the NRS and in a second step these values are compared to cell specific thresholds provided by the SIB-NB. Following “3GPP TS 36.304 V13.2.0, June 2016; User Equipment (UE) procedures in idle mode” and in a similar way as in legacy LTE, the 3GPP standardized S-criteria states that if both values are above these thresholds, the UE considers itself to be in coverage of that cell, camping on it through the initial registration procedure.

How is initial cell re-selection executed in NB-IoT?

Following “3GPP TS 36.304 V13.2.0, June 2016; User Equipment (UE) procedures in idle mode” depending on the received NRS power and the S-criteria failure, the UE may have to start a cell re-selection. UE compares NRS received power to a re-selection threshold based on the proper R-criteria formulas, which may be different for the intra-frequency and the inter-frequency case. All required parameters are received from the actual serving cell against SIB-NB received thresholds. UE follows a R-criteria based ranking procedure among all cells fulfilling the S-criteria with respect to the power excess over another threshold. It is highly recommended to use a hysteresis value in this process in order to prevent frequent oscillating cell reselection (ping-pong effect). Moreover to that it is also recommended to configure a cell specific offset may be applied for the intra frequency case. In Contrary to legacy LTE, 3GPP does not allow priorities for the different frequencies, letting UE to finally select the highest R-criteria based ranked cell which also fulfills the S-criteria suitability.
