| 摘要 |
The invention concerns a method for transmitting digital signals in asynchronous mode whereby the terminals (16, 18) transmit to a common station (20). The communications are transmitted by cells (40, 42, 44, 46) and the terminals successively transmitting at separate periods (60, 62, 64, 66; 70, 72, 74), to each cell being assigned at least two orthogonal codes (C1, C2, C3, C4). The invention is characterised in that the duration of the period during which each terminal transmits, and/or the number of codes assigned to each terminal, and/or the number of symbols of one specific code assigned in a terminal can be selected at each transmission, according to the a specific power level (80). |
