Embodiments of the present disclosure are directed towards a communications system and uplink transmission method which may dynamically adapt to changing conditions of the backhaul network. A traffic engineering element (TEE) is disclosed which receives a request from at least one wireless device for uplink data transmission. The TEE then determines the backhaul conditions of the backhaul network and coordinates uplink data transmissions from at least one wireless device to one or more receivers dependent on the determined backhaul conditions.
