Abstract

See full text

A method is disclosed that includes configuring (202) a UE in a cell to operate with a center frequency of a radio frequency, RF, reception band-width of the UE receiver is different than the center frequency of an RF transmission bandwidth of the cell; puncturing (204) a subcarrier in a downlink signal that, when transmitted over the RF transmission bandwidth corresponds to the center frequency of the UE RF reception band-width to provide a punctured downlink signal; and transmitting (206) the punctured downlink signal to the UE through a transmitter circuit operating within the UE RF reception bandwidth. Related UEs, methods of operating a UE, and network nodes are also disclosed.
