    摘要: Embodiments of the present invention may provide an apparatus and a method for transmitting and receiving a random access channel (RACH) in a single carrier-frequency division multiple access (SC-FDMA) system. A frequency domain RACH signal may be mapped to a localized sub-frequency band of an entire frequency band available to the SC-FDMA system. A guard band including at least one sub carrier may be allocated between the RACH signal band and other channel signal bands. A guard time may be allocated between the RACE signal and other channel signals in the time domain. The RACH signal may include a short message including information related to a mobile station. The RACE signal may be detected in a frequency based method, a time based method or a sliding matched filter based method. Receiver complexity can be decreased if the RACH signal includes a CAZAC code sequence for a preamble. In such a case, a receive delay may be simply calculated and then adjusted more accurately.

    摘要: A method for matching a rate in a mobile communication system causes puncturing or repetition in a fixed pattern, in which puncturing or repetition is applied to each bitstream on transport channels supporting different services in a next generation mobile communication system of the W-CDMA (Wideband Code Division Multiple Access) system. The method comprises the steps of (1) subjecting a bitstream on a transport channel for use in supporting a particular service to channel coding, (2) determining an initial error offset value for use in avoiding all the puncturing only in a particular bitstream among one or more than one bitstreams produced by the channel coding, (3) periodically subtracting a decrement from the determined initial error offset value, for puncturing a bit at a relevant position when a result of the subtraction satisfies a puncturing condition, (4) adding an update error parameter determined as the maximum bit size among TF (Transport Format) transportable during one TTI (Transport Time Interval) of the transport channel after the puncturing to a result of the subtraction, for updating an initial error offset value, and (5) periodically subtracting a decrement from the updated initial error offset value, for determining a position of a relevant bit to be punctured at the next time.

    摘要: Disclosed is a method of transmitting emergency stop control information on a common packet channel (CPCH) in a mobile communication system, which can perform an emergency stop within a less period of time when the user equipment is in a state of transmitting a packet through the CPCH by rapidly transmitting he emergency stop control information. The method of transmitting emergency stop control information on a CPCH is a radio mobile communication system comprises a first step of inserting and transmitting a predetermined bit pattern to a downlink (DL) dedicated physical channel (DPCH) by a universal mobile terrestrial radio access network (UTRAN), a second step of recognizing the particular bit pattern by the UE, and a third step of controlling data transmission through an uplink (UL) CPCH by the UE. Thus, the method according to the invention has an effect of more rapidly transmitting urgent control information through the DL DPCCH or the DPDCH, which are related to the CPCH, or through both of these two channels when the UE is transmitting a packet through the CPCH currently allocated to the UE.

    摘要: A method for allocating common packet channels in a next generation mobile communication system is disclosed. A mobile station maps a signature for indicating a specific common packet channels with scrambling codes and transmits an access preamble including the signature to a system to request allocation of the channel. The system maps a signature of a channel assignment for a desired common packet channel with the scrambling codes to transmit it to the mobile station. The mobile station transmits a message to the system through a corresponding physical channel in accordance with the channel assignment. The mobile station can transmit a collision detection preamble for preventing channel collision to the system by mapping with a specific scrambling code set. At this time, the system can select a scrambling code from a scrambling code set designated by the collision detection preamble and can map the selected scrambling code with the channel assignment.

    摘要: A TFCI transmission scheme using optimal TFCI transmission bit patterns for the DPCH and DSCH in the hard split mode of the W-CDMA standard. The DPCH TFCI bits (TFCI1) and the DSCH TFCI bits (TFCI2) are mapped to their corresponding bit positions and then transmitted such that TFCI code word errors are minimized and communication reliability is improved. When the TFCI1 to TFCI2 ratio is 5:5, the TFCI transmission bit pattern has alternating TFCI1 and TFCI2 bits. For other ratios, such as 1:9. 2:8, 3:7, and 4:6, the bit patterns are obtained by considering situations where the number of TFCI bits is 6 or 7, while bit patterns for respective conjugate ratios (9:1, 8:2, 7:3, and 6:4) are obtained by reversing all 0 and 1 bits of the previously obtained bit pattern for that ratio.
