Method and device for determining routings and for allocating radio resources for the determined routings in a radio communications system
First Claim
1. A method for communicating by radio in a cellular radio communications system having a base station and a plurality of radio stations, the method comprising:
- wirelessly transmitting a message from a subscriber-side transmitting radio station to a subscriber-side receiving radio station through a routing that passes through at least one relay radio station that forwards the message; and
wirelessly sending from the base station information about the routing from the subscriber-side transmitting radio station to the subscriber-side receiving radio station and information about which radio resources are to be used for at least one radio transmission of the message,wherein the message is not transmitted from the subscriber-side transmitting radio station to the subscriber-side receiving radio station until after the base station sends the information about the routing.

Abstract
A method for radio communication between a device and radio stations of a radio communications system having a plurality of radio stations involves transmitting messages from the transmitting radio station to the receiving radio station either directly, or via a routing the passes through one or more radio stations that forward said messages. The device transmits information, which related to one or more routings between a respective transmitting radio station and a receiving radio station and to radio resources that are to be used for at least one message transmission via the routing or routings, to radio stations.

18. A base station for radio communication with radio stations in a cellular radio communications system, comprising:
-
a memory to store adjacent positional relationships between the radio stations of the radio communications system; and a transmitter to wirelessly send information about a routing for a message to be sent wirelessly from a subscriber-side transmitting radio station to a subscriber-side receiving radio station via at least one relay radio station that forwards the message, the transmitter also sending information about which radio resources are to be used for at least one radio transmission of the message, wherein the message is not transmitted from the subscriber-side transmitting radio station to the subscriber-side receiving radio station until after the base station sends the information about the routing. - View Dependent Claims (19, 20)

21. A method for communicating by radio in a radio communications system, the method comprising:
-
receiving a request for wirelessly routing a message on a route from a subscriber-side transmitting radio station to a subscriber-side receiving radio station via at least one relay radio station that forwards the message, the request being received at a base station from the subscriber-side transmitting radio station; determining the routing at the base station by assigning radio resources and at least one relay radio station to the route, the routing being determined based on knowledge of adjacent position relationships between the radio stations; wirelessly sending a routing response from the base station, the routing response containing information identifying the at least one relay radio station and information about which radio resources are to be used; and transmitting the message on the route only after receiving the routing response.
