摘要
Methods of operating a base station serving a cell in a heterogeneous network and at least one relay node serving a subcell of the cell, in which a user equipment unit connects to the network via the base station or the relay node, are provided. The methods include receiving uplink access (Uu) signals at the relay node from the user equipment unit in a first frequency range, and transmitting uplink backhaul (Un) signals from the relay node to the base station in a second frequency range that is different from the first frequency range.
