摘要： A relay operable to relay data between a base station and user equipment of a wireless communications system, a relay-base station pair, methods and computer program products are disclosed. The relay comprises: queuing logic operable, for each user equipment supported by the relay, to form a pending data queue associated with that user equipment, the pending data queue storing received data intended for that user equipment which has yet to be transmitted by the relay over a communications channel between that user equipment and the relay; and scheduling logic operable to schedule transmissions of pending data to each user equipment based on at least one of a size of the pending data queue associated with each user equipment, priority of pending data and channel state information of the communications channel between each user equipment and the relay. In this way, the amount of unnecessary traffic being transmitted between the base station and the relays is reduced, the amount processing resources required in the base station is also reduced and, as a consequence, the deployment of relays within the macro network becomes much more scalable. Accordingly, new relays can be readily deployed where needed without requiring complex and careful network planning.
