1. A method, comprising:appending, by a base station device comprising a processor, bits to an information block to match a size of a radio network identifier, wherein the information block comprises common downlink control information, and wherein the appending results in appended bits;
masking, by the base station device, the information block with the radio network identifier, resulting in a masked information block;
encoding, by the base station device, the masked information block resulting in a code symbol;
transmitting, by the base station device, the radio network identifier to a group of mobile devices using a radio resource control channel before a common control channel is established; and
transmitting, by the base station device, the code symbol to the group of mobile devices on the common control channel.
