摘要

PROBLEM TO BE SOLVED: To improve network efficiency by decreasing unnecessary data transmission and interference signals and to create more appropriate power level with a retransmission in a unit of preamble more faster to improve time delay characteristic.;SOLUTION: When multiple terminal devices use code division multiple access method to transmit data via a common channel, the terminal device 100 selects one of available preamble signatures and one of available access slots to transmit the preamble to a base station 200. The base station 200 attempts preamble acquisition and informs all the terminal devices 100 of the acquisition whatsoever. The terminal device either transmits the data or retransmits the preamble depending on the acquisition result of the preamble.;COPYRIGHT: (C)2004,JPO&NCIPI
