Reduced time packet transmission in a wireless communications system

A power control method, comprising the steps of:

• transmitting from a remote unit, a multi-tone packet having 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;
• receiving, at a base station, the multi-tone packet;
• processing, at the base station, the plurality of tones from the received multi-tone packet to generate a mask placement;
• selecting, using the mask, a tone from the plurality of tones meeting a desired selection criteria;
• transmitting, responsive to the selected tone, a BS packet from the base station, with the BS packet having power information from the power level of the mask at the selected tone;
• receiving, at the remote unit, the BS packet;
• setting, at the remote unit, responsive to the power information, a RU power level;
• and
• transmitting, from the remote unit, a plurality of packets, with the RU power level.

A power control system, comprising:

• A remote unit for transmitting a multi-tone packet having 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;
• a base station for receiving the multi-tone packet, for comparing the plurality of tones from the received multi-tone packet to a threshold, for selecting a tone from the plurality of tones meeting a desired selection criteria, and for transmitting, responsive to the selected tone, a BS packet from the base station, with the BS packet having power information from the power level of the selected tone;
• and
• the remote unit for receiving the BS packet, and for setting, responsive to the power information, a RU power level, and for transmitting a plurality of packets, using the RU power level.

A power control system, comprising:

• a base station for receiving the multi-tone packet, for processing the plurality of tones from the received multi-tone packet to generate a mask, and for selecting, using the mask, a tone from the plurality of tones meeting a desired selection criteria;
• the base station for transmitting, responsive to the selected tone, a BS packet, with the BS packet having power information from the power level of the mask at the selected tone;
• the remote unit for receiving the BS packet, setting responsive to the power information, a RU power level, and for transmitting a plurality of packets, with the RU power level.

A power control system, comprising:

• remote-unit means for transmitting a multi-tone packet having 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;
• base-station means for receiving the multi-tone packet, for comparing the plurality of tones from the received multi-tone packet to a threshold, for selecting a tone from the plurality of tones meeting a desired selection criteria, and for transmitting, responsive to the selected tone, a BS packet from the base-station means, with the BS packet having power information from the power level of the selected tone;
• and
• the remote-unit means for receiving the BS packet, and for setting, responsive to the power information, a RU power level, and for transmitting a plurality of packets, using the RU power level.
