APPARATUS AND METHOD FOR TRANSMITTING/RECEIVING SIGNALS BY USING A PRESET FRAME STRUCTURE IN A WIRELESS COMMUNICATION SYSTEM |
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). |
