Abstract: Various communication systems may benefit from the appropriate monitoring of communication channels. For example, certain wireless communication systems may benefit from downlink control channel monitoring optimized for discontinuous reception mode and/or narrowband operation. A method can include selecting a search space configuration from a plurality of search space configurations for a user equipment. The method can also include operating the user equipment in the selected search space configuration.

Abstract: According to an aspect, there is provided a waveform processing device. The waveform processing device includes circuitry for receiving an input signal including one or more subsequent orthogonal frequency division multiplexing, OFDM, symbol blocks each of which includes a cyclic prefix and an OFDM data block and corresponds to one or more subbands. Further, the waveform processing device includes circuitry for segmenting each OFDM symbol block of the input signal into a set of a pre-defined number of partially overlapping signal blocks of equal length so that non-overlapping samples of the pre-defined number of partially overlapping signal blocks in each set include, in combination, an OFDM data block. Moreover, the waveform processing device includes circuitry for filtering each signal block in each set and for combining the filtered signal blocks in each set using overlap-and-save processing to produce one or more filtered OFDM data blocks for each subband.
