A method of operating a network node that serves a host cell in a cellular communication system wherein an air interface of the cellular communication system is divided up into sequentially occurring frames, each of the frames comprising a plurality of sequentially occurring subframes, the method comprising: at one or more first time intervals (805, 1005), transmitting first control channel information on a control channel that extends over a first bandwidth of a radio frequency spectrum, wherein the first control channel communicates information that is necessary to enable a first type of communication device to receive data from the host cell, the first type of communication device being capable of receiving a signal having the first bandwidth of the radiofrequency spectrum; at one or more second time intervals (807, 1011), transmitting second control channel information on a second control channel of a first M-cell (M-Cell #1, M-Cell #m, M-Cell #n), an M-cell being the collection of aspects/entities of the host cell configured to support a second type of communication device (207, 1701) having reduced receive bandwidth capabilities compared to those of the first type of communication device, wherein the second control channel occupies a second bandwidth of the radiofrequency spectrum, and wherein the second bandwidth is smaller than the first bandwidth, and wherein the one or more second time intervals occur during one or more subframes within a frame and do not coincide with any of the one or more first time intervals; characterized in that at one or more third time intervals, transmitting third control channel information on a third control channel of a second M-cell, wherein the third control channel occupies a third bandwidth of the radiofrequency spectrum, and wherein the third bandwidth is smaller than the first bandwidth, and wherein the one or more third time intervals occur during the one or more subframes within the frame and coincide with one or more of the second time intervals, whereby another communication device of the second type having reduced receive bandwidth capabilities compared to those of the first type of communication device is made capable of being served by the network node, wherein a frequency-wise location of the second bandwidth of the radiofrequency spectrum does not overlap a frequency-wise location of the third bandwidth of the radiofrequency spectrum. at one or more first time intervals (805, 1005), transmitting first control channel information on a control channel that extends over a first bandwidth of a radio frequency spectrum, wherein the first control channel communicates information that is necessary to enable a first type of communication device to receive data from the host cell, the first type of communication device being capable of receiving a signal having the first bandwidth of the radiofrequency spectrum; at one or more second time intervals (807, 1011), transmitting second control channel information on a second control channel of a first M-cell (M-Cell #1, M-Cell #m, M-Cell #n), an M-cell being the collection of aspects/entities of the host cell configured to support a second type of communication device (207, 1701) having reduced receive bandwidth capabilities compared to those of the first type of communication device, wherein the second control channel occupies a second bandwidth of the radiofrequency spectrum, and wherein the second bandwidth is smaller than the first bandwidth, and wherein the one or more second time intervals occur during one or more subframes within a frame and do not coincide with any of the one or more first time intervals; characterized in that at one or more third time intervals, transmitting third control channel information on a third control channel of a second M-cell, wherein the third control channel occupies a third bandwidth of the radiofrequency spectrum, and wherein the third bandwidth is smaller than the first bandwidth, and wherein the one or more third time intervals occur during the one or more subframes within the frame and coincide with one or more of the second time intervals, whereby another communication device of the second type having reduced receive bandwidth capabilities compared to those of the first type of communication device is made capable of being served by the network node, wherein a frequency-wise location of the second bandwidth of the radiofrequency spectrum does not overlap a frequency-wise location of the third bandwidth of the radiofrequency spectrum.
