Abstract
The invention concerns a method of transmitting a control signal by a base station of a digital cellular mobile radio system, said base station comprising at least one array of a plurality of antennas for dynamically creating a beam (,) transmitting said control signal, said transmit beam (,) being adapted to assume different angular positions (,) within a predetermined angular range (,). In accordance with the invention, said method includes a step of allocating to said control signal, in at least one of said transmit subsystems, a predetermined specific time shift so that said transmit beam (,), called a vibrating beam (,), assumes in succession at least some (,) of said different angular positions and enables isotropic broadcasting of said control signal in said angular range (,). The invention also concerns a corresponding base station.
