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 system, method and apparatus for demodulating a received signal using a configurable receiver. The receiver performs the demodulation of a signal according to a selected interference cancellation demodulation scheme. The same receiver can be configured, by setting certain parameters, to behave as a successive interference cancellation (SIC) scheme receiver, a parallel interference cancellation (PIC) scheme receiver, or a hybrid interference cancellation (HIC) scheme receiver. In another aspect of the present invention, the receiver performs its demodulation operation using a single interference cancellation unit (ICU). In addition, the ICU's despreading and respreading functions may be performed by the same processing element.

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.

Abstract translation: 路径检测器（100）提供在预定时间段内检测到前导码信号的速率的统计。 对于检测率低的延迟量段，相关值计算的采样率降低，并且用于前导信号检测的相关器组的数量减少。 通过该减少使得可用的相关器组用于检测消息信号路径，从而提高解码器（200）的RAKE接收机的操作速率，以提高消息信号的吞吐量。 此外，周期性地更新前导码信号检测率的统计，并且当采样率降低的延迟量段的前导信号检测率变高时，用于前导信号检测的相关器集合的数量增加 以将采样率返回到其原始值。

Abstract: A single, common correlation filter (CF) core is provided in a wireless system using CDMA. A plurality of channels with different data rates are provided in the wireless system. The channels provided in the wireless system include the access channel, the maintenance channel, and the traffic channel in which information (e.g., pilot or data symbols or both) is transmitted at the tier 1, tier 2 and tier 3 rates. The data rate for transmitting the information is programmable by digital signal processor (DSP). A user-unique code, such as a PN code, is applied to the information being transmitted in the channels of the wireless system. The information is QPSK modulated and transmitted in any one of the channels at any data rate. The transmitted information is correlated at the smallest data rate (i.e., the tier 1 rate) in the correlation filter (CF) of the wireless system by time multiplexing delayed versions of the PN code to the correlation filter core. The correlated information is then demultiplexed and pilot aided QPSK demodulated. The demodulated information is summed at the proper integer multiple of the tier 1 rate to achieve the tier 2 and tier 3 rates. The three strongest multipaths (in terms of the received power) are selected in a window or time period for optimal information recovery. Furthermore, three outputs from the demodulated information can be provided and combined for temporal diversity. Spatial diversity is achieved by providing a plurality of antennas at each receiver and a single, common correlation filter at each of the plurality of antennas of the receivers in the wireless system.

Abstract: A radio apparatus and base station apparatus that flexibly respond to an increase or decrease in the number of users without being constrained by the number of users. An A-DPCH signal processing section (106) generates dedicated transmission signals corresponding in number to users multiplexed based on the number of users for each sector input from a control station apparatus and outputs the multiplexed signal to a multiplexing section (105). An HSDPA signal processing section (107) selects a transmission destination sector based on an instruction from a base station control section, generates multiplexed transmission data and outputs the multiplexed data to the multiplexing section (105). The multiplexing section (105) code-multiplexes dedicated transmission signals of A-DPCH and packet data in HSDPA communication for each sector and outputs the multiplexed data to a radio transmission section (104). The radio transmission section (104) transmits the multiplexed transmission signal input from the multiplexing section (105) from an antenna (101).

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.
