1. An apparatus comprising:
a processor configured to:
enable a device to perform wireless communications with a cellular base station according to a plurality of communication parameters based on a first device category;
enable the device to receive, as part of the communications with the cellular base station, a machine type communication physical downlink control channel (MPDCCH) that includes downlink control information (DCI); and
identify resource block allocations for the device from one or more DCI fields of the DCI by interpreting, based on one or communication parameters of the plurality of communication parameters, a format of the one or more DCI fields as a first format,
wherein the first format is different from a second format of the one or more DCI fields of the DCI, and
wherein the format of the one or more DCI fields for identifying the resource block allocations is interpreted as the second format when performing wireless communications according to communication parameters based on a second device category different from the first device category.
