摘要： A apparatus and method for allocating synchronization acquisition sequence in a time domain and allocating a cell ID search sequence in a frequency domain. In a method for transmitting a synchronization signal of a base station in a wireless communication system, a binary frequency-domain preamble sequence predetermined for cell ID search and a binary time-domain preamble sequence predetermined for synchronization acquisition are used to determine a complex time-domain preamble sequence except the binary time-domain preamble sequence among the time-domain preamble sequences that are generated according to an Inverse Fast Fourier Transform (IFFT) operation on the binary frequency-domain preamble sequence. The complex time-domain preamble sequence and the binary time-domain preamble sequence are transmitted to a mobile station.

摘要： Methods and apparatus are provided for searching for a peripheral device and transmitting device information in a device-to-device service. First information is transmitted using a first tone in a first region of a search duration. A second tone is determined by transposing a subcarrier index and a symbol index of the first tone. The first information is transmitted through the second tone in a second region of the search duration. First information of a peripheral device is received in the first and the second region of the search duration. The second information is transmitted through a resource region corresponding to the first tone in a third region of the search duration. Second information of the peripheral device is received in the third region of the search duration. Device information of the peripheral device is determined by combining the first and second information of the peripheral device.
