摘要： A method for selecting an access link in a multi-hop relay network includes determining a first effective spectrum efficiency value of a first connection between an endpoint and a base station. The first effective spectrum efficiency value is indicative of the spectrum efficiency from the endpoint to the base station when the first connection is used. The method also includes determining a second effective spectrum efficiency value of a second connection between the endpoint and the base station via a relay station. The second effective spectrum efficiency value is indicative of the spectrum efficiency from the endpoint to the base station when the second connection is used. The method also includes comparing the first and second effective spectrum efficiency values. The method further includes establishing a connection using one of the first or second connections based on the comparison of the first and second effective spectrum efficiency values.
