摘要

PROBLEM TO BE SOLVED: To improve network efficiency by decreasing unnecessary data transmissions and interference signals, and to improve a time delay characteristic by further speedily creating an appropriate power level through retransmission on a preamble unit basis.;SOLUTION: When data are transmitted from a plurality of terminal devices via a common channel according to a code division multiple access system, in the present invention, one of preamble signatures available for a terminal device 100 and one of available connecting slots are selected to transmit a preamble to a base station 200. In the base station 200, capturing of the preamble is attained, all the terminal devices 100 are notified about whether or not the preamble is captured, and according to a result of capturing of the preamble, the terminal device transmits the data or retransmits the preamble.;COPYRIGHT: (C)2011,JPO&INPIT
