In the method for transmitting subcarriers using a pilot structure, pilot subcarriers are repeatedly allocated at predetermined subcarrier spacings and at predetermined symbol spacings in a basic resource block, and the basic resource block is periodically and repeatedly allocated in a time domain and a frequency domain within a subframe, and then the pilot subcarriers and data subcarriers included in the subframe are transmitted. When one or more antennas are used, it is possible to transmit pilot symbols while maintaining predetermined spacings in the time domain and the frequency domain, thereby improving channel estimation performance.

摘要： A method for transmitting a preamble in a scalable bandwidth system is disclosed. The method includes transmitting a primary synchronization channel to which symbols are allocated at intervals of two or more subcarriers, through a specific bandwidth out of an entire system bandwidth at a start time point of a synchronization period, and transmitting a secondary synchronization channel through the specific bandwidth with a prescribed time difference from the primary synchronization channel at the synchronization period.

摘要： A signal transmission method in a multiple antenna system is described. The signal transmission method includes, upon receiving channel state information from a receiving end, estimating a channel according to the channel state information, determining a precoding matrix according to the estimated channel and modifying the signal of the transmitting end using the precoding matrix in a process of mapping a symbol of the signal to a subcarrier, and transmitting the signal to the receiving end.

摘要： A method for transmitting and receiving signals using multi-band Radio Frequencies (RFs) is provided. The method transmits an information unit of a specific layer above a physical layer through a plurality of frequency allocation bands managed by the specific layer and transmits control information identifying each of the plurality of frequency allocation bands. The control information identifying each of the plurality of frequency allocation bands includes a second ID into which a first ID has been converted, the first ID identifying each of the plurality of frequency allocation bands in the physical layer, the second ID identifying each of the plurality of frequency allocation bands managed by the specific layer in the specific layer. To accomplish this, a timing offset is applied to the entirety of a frame or to a preamble (synchronous channel) so that the timing offset is used as the ID. Applying a timing offset to the entirety of a frame or to a preamble (synchronous channel) can achieve an advantage of PAPR reduction.

摘要： A method of transmitting a wideband frame for a wideband system having backward compatibility with a narrowband system includes configuring a wideband carrier by using a set of base carriers, wherein a bandwidth of the base carriers corresponds to a bandwidth of the narrowband system and any one of center frequencies of the base carriers is the same as a center frequency of the narrowband system, and allocating all or some of guard subcarriers between the two adjacent base carriers to a traffic channel when a center frequency spacing between two adjacent base carriers is an integer multiple of a subcarrier spacing. Accordingly, the method can be used to support backward compatibility with the narrowband system. Further, the method can be equally used when the narrowband system co-exists with the wideband system in a guard band defined in a narrowband of a new system.

摘要： Provided is an uplink transmission power control method in a wireless communication system. Said method includes the steps of preferentially determining the transmission power of an uplink control channel, and determining the transmission power of an uplink data channel within the difference between the maximum transmittable power of a terminal and the transmission power of the uplink control channel, wherein the transmission of the uplink control signal through the uplink control channel and the transmission of the uplink data through the uplink data channel are performed at the same time using wireless resources different from one another. The present invention preferentially allocates the transmission power required for the transmission of an uplink control channel, and allocates residual power to an uplink data channel, thereby improving the effectiveness of power allocation when an uplink control signal and an uplink data signal are transmitted at the same time using physical resources different from one another.
