Abstract
A first radio station of a group of radio stations identifies at least one adjacent radio station of the group while using a first radio interface. The first radio station then transmits information concerning the at least one adjacent radio station, which is determined by the first radio station, to a second radio station in the group using a second radio interface. Afterwards, the second radio station transmits path information to the first radio station using the second radio interface. From the path information, it can be inferred with regard to every other radio station of the group, to which radio station respectively adjacent to the first radio station a message addressed to the respective other radio station of the group is to be sent by the first radio station using the first interface.

12. A method for communication in a radio communications system having a group of radio stations and a further radio station, the group including a first radio station and a plurality of other radio stations, said method comprising:
-
determining by the first radio station, at least one neighboring radio station of the group with respect to a first radio interface;
transmitting neighborhood information about the at least one neighboring radio station from the first radio station to the further radio station using a second radio interface;
determining, by the further radio station, path information using the neighborhood information transmitted by the first radio station and additional neighborhood information transferred from the other radio stations of the group relating to neighborhood relationships between the radio stations of the group, the path information defining how a message can be sent from the first radio station to any of the other radio station of the group using the first radio interface; and
transmitting the path information from the further radio station to at least the first radio station using the second radio interface. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A radio station for communication in a radio communication system having a group of other radio stations, comprising:
-
means for receiving via a first radio interface, neighborhood information from the other radio stations about neighboring radio stations of the group neighboring each of the other radio stations;
means for storing the neighborhood information;
means for determining, using the neighborhood information, path information about paths between the other radio stations using a second radio interface; and
means for unsolicited transmitting, via the first radio interface, of the path information required for one of the other radio stations to send a message to any of the other radio stations of the group using the second radio interface, in response to receipt of new information about at least one neighboring radio station neighboring the one of the other radio stations.
