Enhanced-transport format combination power margin for uplink

A communications device for enhanced uplink of High-Speed Uplink Packet Access (HSUPA) of 3G wireless communications, the communications device comprising:

• a mobile unit comprising a receiver and a transmitter, where the mobile unit is operable to:
• use a channel prediction to estimate a power margin of a one or more dedicated channels;
• predict a power margin for an acknowledgement transmission based on transmission parameters;
• reserve a power margin for a channel quality indicator (CQI) transmission;
• and
• determine an Enhanced Transport Format Combination (E-TFC) for an uplink data packet transmission based on an available power margin.

A communications network for enhanced uplink of High-Speed Uplink Packet Access (HSUPA) in third generation (3G) wireless communications, the communications network comprising:

• a mobile transceiver unit, where the mobile transceiver unit is operable to:
• use a channel prediction to estimate a power margin of a one or more dedicated channels;
• predict a power margin for an acknowledgement transmission based on transmission parameters;
• reserve a power margin for a channel quality indicator (CQI) transmission;
• and
• determine an Enhanced Transport Format Combination (E-TFC) for an uplink data packet transmission based on an available power margin;
• and
• a communications network node operable to transmit a power control signal to the mobile transceiver unit.

A method that transmits data for enhanced uplink of High Speed Downlink Packet Access in third generation (3G) wireless communications for a communications network, the method comprising:

• using a channel prediction to estimate a power requirement of a one or more dedicated channels and maintain a power margin for Enhanced Transport Format Combination (E-TFC) selection;
• using a channel prediction to estimate a power margin of a one or more dedicated channels;
• predicting a power margin for an acknowledgement transmission based on transmission parameters;
• reserving a power margin for a channel quality indicator (CQI) transmission;
• determining an E-TFC for an uplink data packet transmission based on an available power margin;
• transmitting a data signal from a mobile unit based on the determined E-TFC;
• and
• transmitting a power control signal from a network node based on the data signal.
