    • The present invention relates to a method of transmitting/receiving random access response information in a radio communication system, and a base station and a terminal thereof. According to the invention, in a case where a base station of a radio communication system transmits response information for random access processing requested from terminals, the base station determines whether to transmit non-contention-based response information and contention-based response information for each of one or more terminals, which requests random access, by one radio resource. When determining to be transmitted by one radio resource, the base station transmits the random access response information configured by the non-contention-based response information and the contention-based response information for each of one or more terminals. In addition, when determining to be transmitted by separate radio resources, the base station transmits the random access response information configured by the non-contention-based response information or the contention-based response information for each of one or more terminals. Accordingly, since the response information is efficiently configured from the point of view of allocation and utilization of radio resources, it can support variable and flexible utilization of physical layer radio resources.
    • 本发明涉及一种在无线电通信系统中发送/接收随机接入应答信息的方法,以及基站及其终端。 根据本发明,在无线通信系统的基站发送从终端请求的随机接入处理的响应信息的情况下,基站判定是否发送基于非竞争的应答信息和基于竞争的响应信息 一个或多个终端通过一个无线电资源请求随机访问。 当确定由一个无线电资源发送时,基站发送由基于非竞争的响应信息配置的随机接入响应信息和针对一个或多个终端中的每一个的基于争用的响应信息。 此外,当确定要由单独的无线电资源发送时,基站发送由基于非竞争的响应信息配置的随机接入响应信息或针对一个或多个终端中的每一个的基于争用的响应信息。 因此,由于响应信息从无线资源的分配和利用的角度高效地配置,因此能够支持对物理层无线资源的可变且灵活的利用。

    • A temperature-adaptive capacitor array used in a TCXO so that the TCXO effectively conducts temperature-compensating in the resonant frequency without the non-monotonicity while a smaller silicon area is used in producing the capacitor array. A number of capacitor arrays allocated in two capacitor banks. Each of the capacitor arrays comprises two or more unit cells, and in turn each unit cell consists of a unit capacitor and a switching element, respectively. All of unit capacitors included in the capacitor arrays are connected each other through a decoder assembly to provide a crystal oscillator with a load capacitance. The unit capacitors belonging to one of the capacitor arrays have the same capacitance with each other. Two unit capacitors belonging to different capacitor arrays, however, have different capacitances from each other. The capacitance of the unit capacitors belonging to each capacitor array is set in consideration of control preciseness required in compensating a frequency deviation in the resonant frequency of the crystal oscillator as the temperature varies in at least a portion of a practical temperature range, within which the crystal oscillator operates.
