摘要： A method for transmitting uplink signals from a user equipment to a base station in a time division multiplexing wireless communication system is disclosed. The method comprises the steps of transmitting a first uplink signal on an uplink subframe or a special subframe that precedes the uplink subframe, by preceding a first timing advance value at a reference time; and transmitting a second uplink signal on the uplink subframe by preceding a second timing advance value at the reference time, wherein the first timing advance value is greater than the second timing advance value, and the first uplink signal is transmitted for an uplink pilot time slot (UpPTS) period of the special subframe if a difference value between the first timing advance value and the second timing advance value is greater than a preset value.

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).
