DATA TRANSMISSION WITHIN A SPREAD-SPECTRUM COMMUNICATION SYSTEM |
| 摘要 |
<p>Rate assignment circuitry (102) detects when a data transmission begins and originally assigns an Orthogonal Variable Spreading Factor (OVSF) code corresponding to low data rate. Over time, a base station controller (101) determines when an OVSF code and/or a repetition rate should be changed (i.e., data rate increased or decreased). The OVSF code and/or the repetition rate is changed in order to gradually increase the data rate, up to a maximum allowable data rate. Once data transmission ceases for a period of time the OVSF code and/or the repetition rate is changed in order to gradually decrease the data rate, down to a lowest allowable data rate.</p> |
