    摘要: A method for converting source data to a channel-modulated signal having a plurality of pairs of in-phase (I) and quadrature-phase (Q) data in a mobile station, wherein the mobile station uses at least one channel, includes the steps of: a) encoding the source data to generate at least one data part and a control part; b) generating at least one spreading code to be allocated to the channel, wherein each spreading code is selected on the basis of a data rate of the data part and the control part and spreading codes are selected so that two consecutive pairs of the I and Q data are correspondent to two points located on same point or symmetrical with respect to a zero point on a phase domain; and c) spreading the control part and the data part by using the spreading code, to thereby generate the channel-modulated signal. The method is capable of improving a power efficiency of a mobile station by reducing a peak-to-average power ratio in a mobile communication system.

    摘要: Provided is a method for allocating radio resources in a mobile telecommunication system. The method for allocating a downlink radio resource in a base station includes retrieving a downlink radio resource allocated to a first mobile terminal if the first mobile terminal does not have a downlink packet, continuously checking whether or not there is a new downlink packet for the first mobile terminal, and retrieving a radio resource allocated to a second mobile terminal if there is a new downlink packet for the first mobile terminal and reallocating the retrieved radio resource to the first mobile terminal.
