    Abstract: The present invention provides a method of transmitting broadcast signals. The method includes, demultiplexing input streams into plural PLPs (Physical Layer Pipes); encoding data of the each PLPs according to each physical layer profiles, wherein the physical layer profiles are configurations based on reception condition, wherein the each physical layer profiles include: LDPC (Low Density Parity Check) encoding the data of the PLP, bit interleaving the LDPC encoded data of the PLP; building plural signal frames by mapping the encoded data of the each PLPs, wherein each signal frame belongs to one of the physical layer profiles, wherein a super frame includes at least two built signal frames; and modulating data in the built plural signal frames by OFDM (Orthogonal Frequency Division Multiplexing) method and transmitting the broadcast signals having the modulated data,

    Abstract translation: 本发明提供一种发送广播信号的方法。 该方法包括：将输入流解复用为多个PLP（物理层管道）; 根据每个物理层简档编码每个PLP的数据，其中物理层简档是基于接收条件的配置，其中每个物理层简档包括：编码PLP的数据的LDPC（低密度奇偶校验），比特交织 PLP的LDPC编码数据; 通过映射每个PLP的编码数据来构建多个信号帧，其中每个信号帧属于物理层简档中的一个，其中超帧包括至少两个内置信号帧; 并通过OFDM（正交频分复用）方式调制内置的多个信号帧中的数据，并发送具有调制数据的广播信号，

    Abstract: A first device receives information related to an absolute location of a positioning reference from the positioning reference; obtains a first PRS reception timing based on a positioning reference signal (PRS) received from the positioning reference; obtains a second PRS reception timing at which a second device receives the PRS from the positioning reference, based on a phase difference value between first RSs received on first subcarriers from the second device; obtains a third PRS reception timing at which a third device receives the PRS from the positioning reference, based on a phase difference value between second RSs received on second subcarriers from the third device; estimates a relative location of the positioning reference, based on the first PRS reception timing, the second PRS reception timing, and the third PRS reception timing; and obtains location information of the first device based on the absolute location and the relative location.

    Abstract: Disclosed are a method and apparatus for determining a position of a Vehicle-to-Everything (V2X) device in a wireless communication system according to various embodiments. Disclosed are a method and apparatus, the method comprising the steps of: receiving a first signal from a first road side unit (RSU) and a second signal from a second RSU through a first antenna and a second antenna distributed over a predetermined distance; measuring a first time difference that is a reception time difference for the first signal and a second time difference that is a reception time difference for the second signal between the first antenna and the second antenna; and determining the position of the V2X device on the basis of the first time difference and the second time difference.
