FAQ's

Describe briefly the Random Access Procedure in NB-IoT

Following “3GPP TS 36.321 V13.2.0, June 2016; Medium Access Control (MAC) protocol specification” RACH procedure has the same message flow as for LTE. In NB-IoT RACH procedure is always contention based and starts with the transmission of a preamble with a typical associated response of a RAR from the eNB. Then follows a scheduled message, msg3, transmitted in order to start the contention resolution process. The associated contention resolution message is finally transmitted to the UE in order to indicate the successful completion of the RACH procedure.

How is NB-IoT device capability informed to the eNodeB?

Following “3GPP TS 36.331 & 36.300” when UE connects to the network, eNB does neither know on which release the UE is built upon, nor which of the optional features defined therein it supports. UE Capability Transfer procedure is typically defined in 3GPP standards in a similar way as in legacy LTE. UE capability transfer is always initiated by eNB side, because the UE cannot know whether the eNB has this information already from the network or from a previous session.
