Packets are received at a first boundary node of a long haul optical communication network which may either interconnect originating and destination communication networks or form an integral part of a single end-to-end network. The method also includes transmitting allocation information about the resource allocation for the UE and the transmit beamforming vector to a communications controller serving the UE. The gate electrode layer has at least one through hole, and a third N-type impurity layer is provided in the P-type well region at a position facing the through hole. The remaining portions of the ball preferably contribute to the moment of inertia of the ball.
