摘要:
The present invention relates to an apparatus and a method for transmitting/receiving signals by using a preset frame structure in a wireless communication system. As there are difficulties ensuring the link capacity and quality for a high speed moving object with the existing frame structure and the antenna arrangement and communication system based on the existing scheme, a new frame structure needs to be proposed. According to one example of those newly proposed frame structures, one frame is composed of 8 subframes, each of the 8 subframes being composed of orthogonal frequency division multiple access (OFDMA) symbols in a range of 11 to 14, and the cyclic prefix (CP) length of the frame is 1/8 or less of an effective symbol length (e.g., 1/8, 1/16, 1/31, 1/64).

Disclosed are an apparatus and method for transceiving a signal using a frame structure appropriate for a high-speed moving body. The method for transceiving a signal using a predetermined frame structure according to the present invention comprises a step of transceiving a signal via a frame having the predetermined frame structure, wherein one frame is constituted by eight subframes, and said frame consists of a type-1 subframe consisting of six orthogonal frequency division multiple access (OFDMA) symbols and a type-2 subframe consisting of seven OFDMA symbols, and said frame has a cyclic prefix length which is either 0, 1/32 of the useful symbol length, 1/64 of the useful symbol length, or 1/128 of the useful symbol length.

摘要:
A method of transmitting data in a wireless communication system is provided. The method includes generating duplicate data by using repetition coding, the duplicate data being the same as original data, shifting the phase of the duplicate data, and transmitting the original data and the phase-shifted duplicate data. The duplicate data is mapped to a modulation symbol having a different size or phase as that of the original data, thus to reduce the PAPR unlike the general repetition coding.
