Abstract
Disclosed is a method performed by a radio access network node of a wireless communication network for handling transmission of LTE or NR signals as well as NB-IoT signals to wireless communication devices over a carrier comprising a plurality of PRBs. The method comprises scheduling the carrier so that at least one of the PRBs is to be used for transmission of NB-IoT signals, called NB-IoT PRBs, and some of the PRBs are to be used for transmission of LTE or NR signals, called LTE PRBs. The method then comprises transmitting LTE or NR signals only in a first group of the scheduled LTE PRBs that experience an interference from the at least one NB-IoT PRB that is lower than the interference experienced from the at least one NB-IoT PRB by a second group of the LTE PRBs, or transmitting LTE or NR signals modulated with a first modulation scheme in the LTE PRBs of the first group, and transmitting LTE or NR signals modulated with a second modulation scheme more robust than the first modulation scheme in the LTE PRBs of the second group.
