摘要:
A communication system node transmits first control channel information on a control channel that extends over a first bandwidth of a radiofrequency resource. The first control channel information is necessary to enable a first type of communication device, capable of receiving a signal having the first bandwidth, to establish a connection with a host cell. A MIB, occupying a second bandwidth-size part of the first bandwidth, is transmitted. The second bandwidth is smaller than the first bandwidth and is receivable by a second type of communication device having reduced receive bandwidth capabilities. The MIB has a first part comprising first part information necessary to enable the first type of communication device to establish the connection with the host cell, and a second part comprising second part information directly or indirectly enabling the second type of communication device to obtain parameters that enable connection establishment with the host cell.
