Patent ID: 8885560

Claim:
A method of operating a network node that serves a host cell in a cellular communication system, the method comprising: at one or more first time intervals, transmitting first control channel information on a control channel that extends over a first bandwidth of a radiofrequency resource, wherein the first control channel communicates information that is necessary to enable a first type of communication device to establish a connection with the host cell, the first type of communication device being capable of receiving a signal having the first bandwidth of the radiofrequency resource; and at one or more second time intervals, transmitting a master information block that occupies a part of the first bandwidth of the radiofrequency resource, wherein the part of the first bandwidth of the radiofrequency resource has a second bandwidth that is smaller than the first bandwidth and is receivable by a second type of communication device having reduced receive bandwidth capabilities compared to those of the first type of communication device, wherein the master information block comprises a first part and a second part, wherein the first part comprises first part information that is necessary to enable the first type of communication device to establish the connection with the host cell, and wherein the second part comprises second part information that directly or indirectly enables the second type of communication device to obtain parameters that enable the second type of communication device to establish a connection with the host cell.
