Abstract: The present invention relates to a preamble signal detection method of a receiving device, and a device therefor. A preamble signal detection method of a receiving device, according to one embodiment of the present disclosure, can comprise the steps of: receiving a plurality of preamble signals for random access through a physical random access channel (PRACH); determining at least one preamble signal corrupted by an interference signal among the received plurality of preamble signals; combining the remaining preamble signals excluding the at least one corrupted preamble signal among the plurality of preamble signals; and detecting a peak value of the combined preamble signals. The study was performed with the support of the “Governmental Depathnent Giga KOREA Business” of the Ministry of Science, ICT and Future Planning

Abstract: Provided are a cell ID determination method and apparatus for a receiving device in a wireless communication system. The cell ID determination method for a receiving device may include: receiving a first synchronization signal and a second synchronization signal; generating a first joint signal by concatenating the first synchronization signal and the second synchronization signal; calculating the correlation between the first joint signal and each of a preset number of cell IDs; and determining a cell ID using the calculated correlations.

Abstract: The present disclosure relates to a method and apparatus for transmitting and receiving signals in a wireless communication system. According to an embodiment of the present disclosure, random access signals including preamble sequences transmitted from a user equipment (UE) may be detected during a plurality of observation periods. A temporary timing advance (TA) value may be determined based on a preamble sequence of a random access signal having greater signal strength among the plurality of random access signals detected in the plurality of observation periods. A final TA value may be acquired based on the temporary TA value according to a result of comparison between the strengths of the random access signals received in the plurality of observation periods and a preset threshold value. A random access response signal including the final TA value may be transmitted to the UE.

Abstract: A method and apparatus is provided for determining, by a receiving end, a correction time value according to ranging access in a wireless communication system. A reception apparatus in a wireless communication system comprises a signal period selector for selecting a first detection time interval and a second detection time interval from a RACH signal for ranging access, the RACH signal including a RACH preamble sequence, a time offset detector for detecting a first time offset and a second time offset, each corresponding to a point of time when the preamble sequence is received, from the selected first detection time interval and the second detection time interval, respectively, and a time offset determiner for determining a correction time value for correcting a point of time when data is transmitted by a transmitting end in the wireless communication system, on the basis of the detected first time offset and the second time offset. This research was carried out with the support of “Pan-government Giga Korea Project” led by the Ministry of Science, ICT and Future Planning.
