CPC H04W 72/0453 (2013.01) [H04W 72/23 (2023.01); H04W 4/70 (2018.02); H04W 72/51 (2023.01)] | 10 Claims |
1. A method performed by a first network node operating in a wireless communications network using a Narrow Band-Internet of Things (NB-IoT), the method comprising:
initiating sending a first indication to a first wireless device operating in the wireless communications network using the NB-IoT, the first indication indicating that a first carrier is a standalone NB-IoT carrier operating within a New Radio (NR) carrier, and the first carrier is:
deployed in one of: a guardband mode and an inband mode, and
shifted away by a frequency offset from a frequency channel raster grid used by the first wireless device; and
initiating sending a second indication to the first wireless device, the second indication indicating that the first carrier is operating with a different Physical Cell Identifier (PCI) than an assumed long-term evolution (LTE) carrier, wherein the first carrier is an anchor NB-IoT carrier, and wherein the NB-IoT anchor carrier:
operates inside the LTE carrier using the inband mode with same PCI as that of the LTE carrier, and
is refarmed to operate within the NR carrier.
