    Abstract: PROBLEM TO BE SOLVED: To provide forward link power control in a cellular system using N
    T /I
    O Values.
    SOLUTION: The mobile station determines a signal strength value according to a communication signal received by way of the communication channel. A pilot channel signal is determined according to a pilot signal transmitted by way of the pilot channel. The signal-to-noise ratio of the communication signal is determined according to the determined signal strength value and the pilot channel signal. The power level of a transmission is controlled according to the signal-to-noise ratio. The pilot channel signal includes pilot energy component and pilot noise component. This pilot noise component is removed to provide a remaining pilot signal. Communication system operations are controlled according to the remaining pilot signal. The power levels of transmissions are controlled by determining the signal-to-noise ratio of a signal within the communication channel and determining a difference signal. The difference signal is formed by determining the difference between determined and desired signal-to-noise ratios.

    Abstract: PROBLEM TO BE SOLVED: To provide techniques to improve an acquisition process in a spread spectrum environment.SOLUTION: Signals from various CDMA systems are spread with various sets of PN sequences, and the PN sequences of each set are uncorrelated to the PN sequences of the other sets. By using uncorrelated PN sequences, the likelihood of detecting a pilot signal from an undesired system is reduced or minimized, and the mean time to acquire the pilot signal from a desired system is improved. A mobile station acquires the pilot signal by processing a received signal with a first set of the PN sequences corresponding to a first hypothesis of acquired particular signal. When the acquisition of the pilot signal is a failure, a second set of the PN sequences corresponding to a second hypothesis is selected and the received signal is processed. The PN sequences in the second set are uncorrelated to the PN sequences in the first set.

    Abstract: PROBLEM TO BE SOLVED: To determine an effective use of reception diversity, and to reduce power consumption.
    SOLUTION: A control system 210 determines a demand level for use in a communication resource. A transmitter communicates with a message indicating the use of the reception diversity at a mobile station based on a determined demand level. In another aspect, a receiver 200 receives one channel and determines a transmission power level of the channel at a lower-limited transmission power level or an upper-limited transmission power level. The control system 210 controls the reception diversity by selecting the number of receiver chains 290 based on the determined transmission power level. In another aspect, the receiver 200 receives one channel and determines one channel condition of the channel and the duration of the channel condition. The control system 210 selects the number of the receiver chains 290 based on the determined channel condition and the duration.
