Abstract
Embodiments can relate to an apparatus for interference mitigation in a wireless communication. The apparatus can comprise at least one processing element arranged to extract, from a received PDCCH or EPDCCH signal, modulated symbols; the modulated symbols having been modulated using a linear m-ary modulation constellation. The apparatus also comprises a demodulator to demodulate the extracted PDCCH or EPDCCH modulated symbols; the demodulator being operable to demodulate the extracted symbols according to the linear m-ary modulation constellation.
