There is no PHICH channel in NB-IOT device then how UE will receive HARQ feedback?
I am new to IOT and came across two possible deployment options (Cat M1- eMTC and NB-IOT). I know LTE technology (Radio and Core both) but I could not understand how these options would be integrated with existing LTE network. Please someone put some light on that.
NB-IOT device uses different Rb coding mechanism and different BW, Is it same ENB supports NB-IOT device and normal UE ?is same ENB supports how MAC and PHY layer works ,because MAC and PHY functionality is different for NB-IOT and normal UE
