    • Various communication systems may benefit from an improved signaling protocol. For example, communication systems may benefit from an improved network support for a narrowband internet of things in a hosting long term evolution carrier. A method, in certain embodiments, includes shifting a frequency of a downlink long term evolution channel by a pre-determined amount. The shift causes a duplex distance between the downlink long term evolution channel and an uplink long term evolution channel to change. The method includes blanking at least one overlapping radio resource in at least one of the uplink long term evolution channel or an uplink narrowband internet of things channel. The uplink narrowband internet of things channel and the uplink long term evolution channel at least partially overlap. In addition, the method includes receiving data on the uplink narrowband internet of things channel and an additional uplink narrowband internet of things channel at a network entity from a user equipment.

    • It is described a technique to compensate the in-band ripple of filters at the IFFT prior to filtering in the transmitter (100) or, for the receiver (200), in the FFT after filtering. A transmitter (100) comprises a multiplier (128) for multiplying at least one transmitter coefficient (130a, 130b) to an input signal (103a, 103b) of an inverse Fourier transformer (104) which is followed subsequent signal processing chain (108), thereby reducing a ripple on the output (110) of said signal processing chain (108). A receiver for receiving a transmission signal comprises a signal processing chain for processing the transmission signal a multiplier for multiplying at least one receiver coefficient to an output signal of a Fourier transformer to which the output of the signal processing chain is fed to thereby reduce a ripple on said output signal of said Fourier transformer.
