    Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for transmitting and receiving transmission rate of a remote unit, in a CDMA communication system utilizing a continuous reverse-channel transmission.
    SOLUTION: A present transmission rate is modulated in the polarity of a Walsh code, in a communication system utilizing a continuous reverse-channel transmission through a Welsh-code redundant transmission. In other words, the transmission rate is modulated in such manner that the remote unit in operation under a specific transmission rate by utilizing the continuous reverse-channel transmission establishes the polarity in every Walsh code, in accordance with a present or a future data-traffic channel rate. The specific communication rate is modulated on reference symbols 501 to 517 by uniformly establishing the reference symbols 501 to 517 in a digit 1 or 0, in the communication system utilizing a reference-coherent (RC) transmission.

    Abstract: Power control in a spread spectrum communication system takes place by determining a speed of a remote unit (405) and assigning as a power-control threshold a target threshold based on the determined speed (410). An instantaneous threshold value is created (415) based on frame-quality information and the target threshold. An energy of a power-control group transmitted (430) from a remote unit is compared to the instantaneous threshold value and a power-adjustment command is determined. The power-adjustment command is transmitted to the remote unit instructing the remote unit to adjust its power accordingly.

    Abstract: In a communication system where a continuous reverse channel transmission is utilized by redundant transmission of Walsh codes, a current transmission rate is modulated onto Walsh code polarity. In particular, a remote unit operating at a particular transmission rate utilizing a continuous reverse channel transmission modulates the transmission rate by setting the polarity of each Walsh code depending upon the current or future data traffic channel rate. In communication systems where a Reference Coherent (RC) type transmission is utilized, the particular transmission rate is modulated onto the reference symbols (501-517) by setting the reference symbols (501-517) equal to a binary "1" or "0".

    Abstract: The method includes acquiring a signal (501); inputting (502), at a first time, a received symbol to a demodulator having a plurality of outputs to produce a set of early outputs; inputting (504), at a second time, the received symbol to the demodulator to produce a set of on-time outputs; inputting (505), at a third time, the received symbol to the demodulator to produce a set of late outputs; and comparing (506) at least one output in the set of early outputs with at least one output in the set of late outputs to produce a timing measure.
