PROBLEM TO BE SOLVED: To increase the traffic amount of outgoing line remarkably in comparison with the traffic amount of incoming line by dividing information to be transmitted through the outgoing line to one radio terminal more than spreading codes to be used for communication through the incoming line, spreading and transmitting the respective divided pieces of information while using mutually different spreading codes. SOLUTION: A radio base station temporarily dividedly stores the information sent from a server through a network into two buffers 22a and 22b. When the permission of transmission is received from a control part 21, the buffers 22a and 22b send the stored information to a transmission part 24. The transmission part 24 performs the spread spectrum of respective transmitted information with different pseudo random codes PN1-PN2 through respective spread spectrum parts 24a-24b and transmits it through an antenna 26 to the radio terminal while using a carrier frequency. Thus, the signal transmission speed of outgoing line can be accelerated and when receiving the large capacitance of information at the radio terminal, waiting time can be shortened. |
