    Abstract: A method for transmitting and receiving a signal and an apparatus for transmitting and receiving a signal are disclosed. The method for receiving the signal includes receiving (S210) the signal in a first frequency band, identifying (S220) a first pilot signal including, a cyclic prefix obtained by frequency-shifting a first portion of an useful portion of the first pilot signal and a cyclic suffix obtained by frequency-shifting a second portion of the useful portion of the first pilot signal from the received signal, demodulating (S220) a signal frame including a physical layer pipe (PLP) to which a service stream is converted, by an orthogonal frequency division multiplexing (OFDM) scheme, using information set in the first pilot signal, parsing (S230) the signal frame and obtaining the PLP and obtaining (S240) the service stream from the PLP.

    Abstract: According to one embodiment, a method of transmitting a broadcasting signal includes: encoding data; encoding signaling data by an LDPC (Low Density Parity Check) scheme; building a signal frame based on at least one preamble data symbol having the encoded signaling data and a data slice having the encoded data; inserting at least one pilot into the signal frame with a specific pattern and modulating the signal frame by an OFDM (Orthogonal Frequency Division Multiplexing) method; and transmitting the modulated signal frame. A signaling block having the signaling data is repeated in the at least one preamble data symbol in a frequency domain by a bandwidth. The bandwidth of the signaling block corresponds to a number of active subcarriers assigned to a single channel.

    Abstract: A method of measuring a location of a first user equipment (UE) in a wireless communication system includes the first UE receiving control information from at least one of a plurality of base stations and the first UE transmitting a first reference signal to the plurality of base stations based on the control information. The control information includes information indicating transmission of the first reference signal to the first UE with maximum power, and the location of the first UE is measured by the plurality of base stations based on the first reference signal.
