摘要： A user equipment and method of transmitting symbols by the user equipment in a wireless communication system. The method includes: generating a first symbol by adding a cyclic prefix (CP) to a first inverse fourier transformed samples, the CP being copied from the first fourier transformed samples; generating a next consecutive second symbol by adding a CP to a second inverse fourier transformed samples, the CP being copied from the second fourier transformed samples; removing samples overlapped with the first symbol from the next consecutive second symbol when the next consecutive second symbol is to be advanced in transmission timing; and transmitting the first symbol and the next consecutive second symbol to a base station.

摘要： A user equipment and corresponding method of transmitting symbols by the user equipment in a wireless communication system. The method includes: generating a first symbol and a second symbol, each symbol including a cyclic prefix and a data part; manipulating a part of the second symbol to be ignored in transmission so that the first symbol and a remaining part of the second symbol are transmitted without overlapping, when the first symbol and the second symbol are overlapped due to a transmission timing advance of the second symbol; and transmitting the first symbol and the second symbol at each transmission timing to the base station.

摘要： A method of adjusting transmission timing, a method of continuously transmitting packets, and a mobile station are provided. The method of adjusting the transmission timing includes adjusting the transmission timing according to a transmission timing adjustment command when the transmission timing adjustment command is received from a receiving side; and creating a cyclic prefix (CP) in consideration of a part of a CP of a next symbol which overlaps with a previous symbol on a time axis on the basis of the adjusted transmission timing. Accordingly, it is possible to prevent deterioration in reception performance and minimize reception complexity even when packet transmission timing is adjusted at a transmitting side using an OFDMA or analogous radio access scheme.

摘要： A user equipment and corresponding method of transmitting symbol by the user equipment in a wireless communication. The user equipment transmits a plurality of symbols to a base station, each symbol including a cyclic prefix and a data part. The method includes: receiving a timing adjustment command from the base station, the timing adjustment command advancing a transmission timing of symbol after a predetermined time; and transmitting a timing adjusted symbol to the base station. A length of the timing adjusted symbol is varied so that the timing adjusted symbol does not include an overlapping part with a previous symbol.

摘要： A method of transmitting pilot signals in a system which performs communication using two or more earners comprises transmitting first pilots and second pilots from at least one user equipment to a base station, the first and second pilots, which are transmitted from the at least one user equipment, being multiplexed by code division multiplexing, and the first and second pilots, which are transmitted from a specific user equipment, having different transmission powers, and transmitting data from the at least one user equipment to the base station depending on the first pilots and the second pilots. Since many UEs can transmit CQ pilots, exact channel estimation can be performed and thus communication efficiency can be improved.

摘要： A method for indicating a combination between a codeword and a layer in a MIMO communication system, a layer mapping method, and a data transmission method using the same are disclosed. A minimum number of codeword-layer mapping combinations from among all available combinations based on the numbers of all codewords and all layers are pre-defined in consideration of a ratio of a codeword to a layer, a reception performance of a receiver, and reduction of combinations, so that a data transmission method using the predefined combinations is implemented. If a specific one codeword is mapped to at least two layers, a diversity gain can be acquired.
