Reduced time packet transmission in a wireless communications system |
摘要 |
System and method for reducing acquisition time of packets in a FDD system, such as a spread-spectrum or OFDM system. A remote unit transmits a multi-tone packet. The multi-tone packet has a plurality of tones with each tone having a different power level, and at a different frequency, from other tones in the plurality of tones. The base station receives the multi-tone packet. The base station compares the plurality of tones from the received multi-tone packet to a threshold or other selection criteria. A tone is selected from the plurality of tones meeting desired selection criteria. Based on the selected tone, the base station transmits a BS packet with the BS packet having power information from the power level of the selected tone.
