摘要： A method for power control in spread spectrum communication systems includes a first step of providing multiplexed registers coupled to a control circuit and controlled by a control signal. A next step includes measuring a transmit power. Next steps include receiving TPC information, and determining whether the TPC information calls for an increase or decrease in power. A next step includes comparing the TPC information to the last TPC information, wherein if the TPC information is the same as the last TPC information, calculating a new power control value using the TPC information and measured transmit power, and writing the new power control value to the next selected register. A next step includes applying the control signal corresponding to the next selected register to the multiplexer to couple the value of next selected register to the control circuit.

摘要： A communication unit is provided having a transmitter and a processor (103). The processor (103) receives information (105) representative of a configuration of physical channels (107). The processor (103) determines a scaling factor responsive to the information (105) and facilitates scaling a signal (109, 111) provided by a combination of the channels utilizing the scaling factor. The scaled signal (109, 111) is provided to the transmitter.

摘要： A method for power control in spread spectrum communication systems includes a first step of providing multiplexed registers coupled to a control circuit and controlled by a TPC-derived control. One register containing an increased power control value and the other register a decreased power control value. A next step includes measuring a transmit power. A next step includes precalculating an increased and decreased power control value using the measured transmit power. Next steps includes comparing precalculated power control values to those previously stored in the registers, and writing only those changed values to their corresponding registers. A next step is receiving TPC information, followed by determining the requested power change from the TPC information, wherein if the information for the next slot is the same as for the current slot, writing the associated precalculated value to the next register to be selected. A last step is applying the value of the next selected register to the control circuit.

摘要： A mobile station (102) has electrical circuitry (301) that operates to reduce power consumption. A synthesizer (318) is tuned so that a receiver (314) receives a home radio frequency (RF) signal during a receive slot (504) of a PCH subframe (209). A controller (310) detects if an upcoming subframe has an uplink requirement and if data from the home RF signal indicates that an idle condition exists. If the upcoming subframe does not have an uplink requirement, synthesizer (318) is tuned during a long idle slot (506) of PCH subframe (209) to measure signal strengths of two peripheral RF signals. If the idle condition does exist, electrical circuitry (301) is placed into a low power mode throughout a transmit slot (508), a receive slot (512), a long idle slot (514), and a transmit slot (516).
