Method and program for channel modification in a cell of a mobile radio access network

A tangible, non-transient computer-readable medium having computer-executable instructions for controlling a base station for a radio coverage area configured to be operably coupled to a macro cell of a mobile radio access network stored thereon, wherein the macro cell has a first transmitter for transmitting a first control channel signal on a broadcast channel and the macro cell overlaps at least partly with the radio coverage area, the radio coverage area being created by a second transmitter, the computer-executable instructions, when executed by a processor, causing the processor to perform the steps of:

• generating a second control channel signal;
• and
• transmitting, on the same broadcast channel as the first control channel signal, the second control channel signal using the same physical layer configuration as the first control channel signal;
• wherein the second control channel signal is synchronized to the first control channel signal, wherein the second control channel signal includes a duplication of the first control channel signal, and wherein the second control channel signal differs from the first control channel signal in at least one information element carried by the first control channel signal.
