    Abstract: A method and apparatus for automatically correcting the frequency of a local oscillator of a receiver. A primary common pilot channel (CPICH) code sequence is generated by a CPICH code generator based on a reference cell identification signal and a frame start signal. The received despread CPICH code sequence is used to generate an estimated frequency error signal. A control voltage generator based on the estimated frequency error signal generates a control voltage signal. The CPICH code generator generates the CPICH code sequence based on signals received from a high speed downlink packet access (HSDPA) serving cell when HSDPA is active, or a timing reference cell when HSDPA is not active. The present invention achieves full maximum ratio combining gain when space-time transmit diversity (STTD) is used, even without receiving a transmit diversity indication.

    Abstract translation: 一种自动校正接收机本地振荡器频率的方法和装置。 基于参考小区识别信号和帧起始信号由CPICH码发生器生成主公共导频信道（CPICH）码序列。 所接收的解扩CPICH码序列被用于生成估计的频率误差信号。 基于估计的频率误差信号的控制电压生成器生成控制电压信号。 CPICH码发生器基于HSDPA有效时从高速下行链路分组接入（HSDPA）服务小区接收到的信号或HSDPA未激活时的定时参考小区产生CPICH码序列。 即使没有接收到发射分集指示，当使用空时发射分集（STTD）时，本发明也实现了全部最大比合并增益。

    Abstract: A method and apparatus for compensating for phase noise of symbols spread with a long spreading code are disclosed. To compensate for the phase noise, a phase error estimate is generated from despread symbols with a short spreading code. A phase correcting phasor is applied to chip rate data before despreading the data with a long spreading code. A signal-to-interference ratio (SIR) on a common pilot channel (CPICH) may be calculated by spreading the data with a parent spreading code in an orthogonal variable spreading factor (OVSF) code tree and by combining symbols. Alternatively, a magnitude of the symbols may be used in estimating the SIR. The SIR of a channel using a short spreading code and an SIR of a channel using a long spreading code are measured. The SIR of the channel with the long spreading code may be compensated in accordance with a difference between degradation of the SIRs.

    Abstract: A wireless communication system implements wireless communications between a base station and a plurality of User Equipments (UEs) including paging of UEs by initially processing paging indicator information. A first embodiment involves a UE's physical layer L1 being configured for interpreting a paging indicator (PI) to activate a preset decoding configuration to process paging data in a pre-specified paging channel (PCH). A second embodiment involves the physical layer control of a next higher level, L2, interpreting the paging indicator and configuring the physical layer L1 to process paging data in a pre-specified PCH.

    Abstract: A method for emulating signal impairments to enable dynamic evaluation of transmit and receive modem performance through the use of computer-generated models enabling both an evaluation of system performance as well as a comparison of results obtained from system designs respectively exposed to both impaired and unimpaired conditions to enable direct comparison as well as comparison with standardized measurement values to facilitate system design activities prior to any hardware implementation.
