    • There are provided spread spectrum signal generating devices and methods in a transmitter of a mobile communications system using a plurality of logical channels. In the spread spectrum signal generating devices, a multiplexer time multiplexes a pilot channel signal and a control channel signal which are output at substantially constant power levels. A first orthogonal encoder orthogonally spreads the output of the multiplexer with an orthogonal code. A second orthogonal encoder orthogonally spreads voice channel data of a variable bit rate with an orthogonal code. A third orthogonal encoder orthogonally spreads packet channel data of a variable bit rate with an orthogonal code. An IQ signal mapper adds the outputs of the first and third orthogonal encoders, outputs the added signal as a first channel signal, and outputs the output of the second orthogonal encoder as a second channel signal. A PN spreader spreads the first and second channel signals with PN codes and outputs a final spectrum spread signal, which exhibits a substantially minimized peak-to-average power ratio.
    • 在使用多个逻辑信道的移动通信系统的发射机中提供扩频信号产生装置和方法。 在扩展频谱信号发生装置中,多路复用器以基本上恒定的功率电平输出导频信道信号和控制信道信号。 第一正交编码器使用正交码对多路复用器的输出进行正交扩展。 第二正交编码器用正交码对可变比特率的语音信道数据进行正交扩频。 第三正交编码器使用正交码对可变比特率的分组信道数据进行正交扩展。 IQ信号映射器将第一和第三正交编码器的输出相加,输出相加的信号作为第一信道信号,并将第二正交编码器的输出作为第二信道信号输出。 PN扩展器用PN码扩展第一和第二信道信号,并输出最终的频谱扩展信号,其表现出基本上最小化的峰均功率比。

    • An apparatus and method for efficiently operating a fast feedback channel in a wireless communication system are provided. A method for operating a feedback channel in a Base Station (BS) of a wireless communication system includes identifying feedback information types of one or more feedback channels intended to be deallocated among a plurality of existing allocated feedback channels for a Mobile Station (MS), activating a bit corresponding to the identified feedback information type in a ‘deallocation bitmap’ field within a DownLink (DL) control signal, and transmitting the DL control signal to the MS. Among the feedback information types of the plurality of existing allocated feedback channels, the feedback information type having the smallest value corresponds to the highest priority bit among bits within the ‘deallocation bitmap’ field.
    • 提供了一种用于在无线通信系统中有效地操作快速反馈信道的装置和方法。 一种用于在无线通信系统的基站(BS)中操作反馈信道的方法包括识别用于移动台(MS)的多个现有分配的反馈信道中旨在被释放的一个或多个反馈信道的反馈信息类型, 在DownLink(DL)控制信号中的“解除分配位图”字段中激活与所识别的反馈信息类型相对应的位,并将DL控制信号发送到MS。 在多个现有分配的反馈信道的反馈信息类型中,具有最小值的反馈信息类型对应于“取消分配位图”字段内的比特中的最高优先级位。
