1. A method of operating a base station in a mobile telecommunications system, the method comprising:
- the base station communicating directly with a mobile station via a first channel;
the base station receiving a request for a higher rate connection from the mobile station;
the base station instructing the mobile station to broadcast a random access burst for receipt by a plurality of relay stations;
the base station receiving, from each of one or more relay stations, information indicative of a quality of reception of the random access burst from the mobile station;
the base station using the information from each of the one or more relay stations as a basis for selecting one of the one or more relay stations; and
the base station communicating indirectly with the mobile station via the selected relay station.

Abstract
A mobile station is operated in a telecommunications system that includes a base station and one or more relay stations. The mobile station communicates directly with the base station via a first channel. To facilitate selection of a suitable relay station, the mobile station broadcasts a burst for receipt by a plurality of relay stations. Relay stations each measure a quality of the received burst and communicate this information to the base station, which uses the information to select a most suitable one of the relay stations for use in carrying on indirect communications between the base station and the mobile station.
