Apparatus for transmitting and receiving a signal and method of transmitting and receiving a signal

摘要

A method of transmitting and receiving a signal and an apparatus for transmitting and receiving a signal are disclosed. The method includes receiving the signal of a first frequency band, obtaining layer-1 information from a preamble of the first time-frequency slicing (TFS) signal frame of the received signal, said layer-1 information including a radio frequency (RF) channel identifier of a first TFS signal frame including the PLP in a super frame of TFS structure, and an identifier of a starting radio frequency (RF) channel which can receive the PLP in the TFS signal frame, parsing the TFS signal frame using the layer-1 information and obtaining a physical layer pipe (PLP) of the TFS signal frame, and converting the PLP to a service stream.

1. A method of transmitting a signal, the method comprising:
converting a service stream for delivering a service to a physical layer pipe (PLP); building a time-frequency slicing (TFS) signal frame comprising the PLP and layer-1 information; modulating the TFS signal frame by an orthogonal frequency division multiplexing (OFDM) scheme in order to output a modulated signal; and transmitting the modulated signal via at least one radio frequency (RF) band signal, wherein the layer-1 information includes an identifier (ID) of a radio frequency (RF) channel that includes the PLP in a first (1st) TFS signal frame of a super frame of a TFS structure, an ID of a starting RF channel of the TFS signal frame, and an index of a current RF channel within the TFS signal frame, wherein the ID of the RF channel is included in a configurable part of the layer-1 information, wherein the configurable part is changed in unit of the super frame, wherein the TFS signal frame further comprises signal frame identification information that comprises a portion, a cyclic prefix obtained by frequency-shifting a first part of the portion, and a cyclic suffix obtained by frequency-shifting a second part of the portion, and wherein the first part of the portion is a foremost part of the portion and the second part of the portion is a rearmost part of the portion.
