    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: An apparatus and method for maximizing throughout for HARQ transmissions is provided. Systematic and prodeduralized RV selection is facilitated by determining the parameter “s” by using two important factors affecting the system throughout, specifically the coding gain varying according to the code rate and the balance between energy per systematic bit and energy per parity bit.

    摘要: A communication system having multiple channels is disclosed. An apparatus for controlling outer loop power in the communication system having the multiple channels includes a step adjustment unit for re-setting height of a step size for power controlling with reference to a CRC result, when the CRC result is received from a base station; and a power controller for determining a target signal to interference ratio (SIR) with reference to the CRC result and the re-set step size information, and transmitting the determined target SIR to the base station. Power controlling operation can be more effectively performed in the communication system having the multiple channels.
