Abstract
In a radiotelephone system, the control channel in all cells in an area can be simulcasted. A microcell base station may be provided with a receiver to listen on the umbrella cell control channel for messages, in addition to listening on its own control channel for control information and call accesses, to facilitate the appropriate assignment of a call to a cell. Also, a microcell can share a control channel with an umbrella cell provided interference between the control channels is not excessive. Further, microcells can share a common control channel independent of the overlying macrocell structure.
