In at least one embodiment time separated pulse pairs are generated, followed by amplification to increase the available peak andor average power. The support frame includes a support module connected with the rail section, and two wheel modules attached to the sides thereof in a replaceable manner, and in which at least one of the wheels is rotatably supported. , an operation environment that is personalized in a given apparatus and handled in another apparatus and remains in it, thereby improving the operability and security. During periods of frame dropping prior to encryption, the state vector is disabled, thereby allowing for sequential encryption of the data frames. The base station transmits a data channel signal using a beamforming weight corresponding to the time area number fed back from the terminal. The end option node has a single exit.
