Abstract: A base station for controlling transmission power during the establishment of a communication channel utilizes the reception of a short code during initial power ramp-up. The short code is a sequence for detection by the base station which has a much shorter period than a conventional access code. The ramp-up starts from a power level that is lower than the required power level for detection by the base station. The power of the short code is quickly increased until the signal is detected by the base station. Once the base station detects the short code, it transmits an indication that the short code has been detected.

Abstract: A method for determining a threshold value for controlling output power of a mobile communication terminal in a W-CDMA system, includes: calculating a first value by dividing an average energy per a PN chip of downlink DPCCH by a total received power spectral density of downlink; calculating a second value by dividing the total received power spectral density of downlink by a white noise power spectral density; calculating a chip unit SIR by adding the first and second values; and determining a symbol unit threshold value for controlling ON/OFF of terminal output power by adding the chip unit SIR and a processing gain according to the number of chips per symbol. Accordingly, a symbol unit threshold value for controlling output power can be easily determined irrespective of a value of a data rate and a spreading factor.

Abstract: A path detector (100) provides statistics of rates at which preamble signals are detected within a predetermined time period. For a delay amount segment where the detection rate is low, the sampling rate of correlation value calculation is reduced, and the number of correlator sets used for the preamble signal detection is reduced. Correlator sets made available by that reduction are used to detect message signal paths, thereby raising the operating rate of the RAKE receivers of a decoder (200) to improve the throughput of the message signals. Further, the statistics of the rates of preamble signal detections are periodically updated, and when the preamble signal detection rate of the delay amount segment where the sampling rate was reduced becomes higher, the number of the correlator sets used for the preamble signal detection is increased so as to return the sampling rate to its original value.
