A communication system includes at least a large service area (LSA) base station having a LSA geographical service area and a small service area (SSA) base station having a SSA geographical service area that is smaller than the LSA geographical service area and at least partially overlaps the LSA geographical service area in an overlap region. A first logical control channel, assigned to the LSA base station, and a second logical control channel, assigned to the SSA base station, have common control information that is the same. A controller in the system allocates transmission of the common control information from at least one of the base stations over a physical channel having a defined transmission time and transmission frequency. If transmission of the common control information is allocated from both base stations, the common control information is allocated for transmission by both base stations over the physical channel.
