A radio communications system has a plurality of transmitter/receiver stations.
At a certain point in time, a first set of said transmitter-receiver stations forms
a group of active stations, which communicate with a mobile terminal device. When
a requirement is detected, after a connection has been relayed, the number of active
of stations is increased by at least one additional station. Thereafter, at least
the station having the lowest transfer quality is removed from the active stations
in order to close the connecting relay.
