Abstract: An apparatus and a method for detecting a cell ID(Identification) in a mobile communication system are provided to improve a detection performance by arranging codes having an orthogonal relation in one group and minimizing an influence from each other. An apparatus for detecting a cell ID(Identification) in a mobile communication system includes an FFT(Fast Fourier Transform)(602), a reference signal selector(604), an inverse scrambler, and an energy detection unit(616). The FFT transforms a demodulated input signal to a signal of a frequency axis. The reference signal selector selects a reference signal from the signal which is transformed to the frequency axis. The inverse scrambler performs and outputs an inverse scrambling for all scrambling codes included in one group. The energy detection unit calculates an inverse scrambled energy, and detects a cell ID in case of a maximum energy value.

Abstract: A mobile station transmits a pilot signal, a common channel signal and a traffic channel signal for a reverse link. The mobile station normally transmits the common channel signal and the pilot signal at a predetermined transmission power, and transmits the pilot signal at a transmission power higher than the predetermined transmission power over a predetermined duration. The pilot signal transmitted over the predetermined duration is spread with a first spreading code over the duration where the pilot signal is transmitted at the predetermined transmission power, and is spread with a second spreading code over the duration where the pilot signal is transmitted at the transmission power higher than the predetermined transmission power.

Abstract: A device and method for controlling communication on a reverse link in a mobile communication system includes a measurer, a controller, and a reverse link transmitter according to an embodiment of the present invention. The measurer detects a power control bit from a channel signal received on a forward link and measures the reception strength of the channel signal using the detected power control bit. The controller compares the reception strength with a threshold and generates a signal for controlling transmission on a reverse link if the channel status of the forward link is determined to be bad during the comparison. The reverse link transmitter stops channel transmission on the reverse link in response to the transmission control signal.
