16 Claims

1. A method performed by a base station in a wireless communication system, the method comprising:

transmitting, to a terminal, information on a frame structure among a plurality of frame structures, wherein the information on the frame structure includes a subcarrier spacing and a cyclic prefix of the frame structure; and

transmitting, to the terminal, scheduling information based on a transmission time interval (TTI) of the frame structure, as a unit of a scheduling,

wherein the plurality of frame structures includes a first frame structure and a second frame structure,

wherein a subcarrier spacing of the first frame structure is 15 kHz and a subcarrier spacing of the second frame structure is 30 kHz,

wherein a first TTI of the first frame structure and a second TTI of the second frame structure each include 14 symbols, and a duration of the first TTI is 1 ms and a duration of the second TTI is 0.5 ms,

wherein each of a symbol duration of a first symbol and a symbol duration of an eighth symbol in the first TTI is longer than a symbol duration of any of other symbols in the first TTI, and a symbol duration of a first symbol in the second TTI is longer than a symbol duration of any of other symbols in the second TTI,

wherein the symbol duration of the first symbol in the first TTI equals a sum of the symbol duration of the first symbol and a symbol duration of a second symbol in the second TTI such that two symbols in the second TTI are time synchronized with one symbol of the first TTI,

wherein a duration of a cyclic prefix of the first symbol in the second TTI is TCP.0/2+(TCP.0-TCP.1)/2 and a duration of an orthogonal frequency division multiplexing (OFDM) symbol of the first symbol in the second TTI is Tsymb/2, where Tsymb is a duration of an OFDM symbol in the first TTI, TCP.0 is a duration of a cyclic prefix of each of the first symbol and the eighth symbol in the first TTI and TCP.1 is a duration of a cyclic prefix of another symbol in the first TTI, and

wherein a duration of a cyclic prefix of the second symbol in the second TTI is TCP.1/2 and a duration of an OFDM symbol of the second symbol in the second TTI is Tsymb/2.
