說明書
The following describes in detail relationships between a radio frame, a subframe, a slot, and an OFDM symbol. For an LTE system, one radio frame includes 10 subframes, and each subframe includes two slots. If a data transmission configuration is a normal cyclic prefix and a subcarrier spacing is 15 KHz, each subframe includes 14 OFDM symbols, and each slot includes seven OFDM symbols. If a data transmission configuration is an extended cyclic prefix and a subcarrier spacing is 15 KHz, each subframe includes 12 OFDM symbols, and each slot includes six OFDM symbols. In an LTE system, a radio frame may be represented by a radio frame index number, and the radio frame index number is any integer value in 0 to 1023. A subframe may be represented by a position in a radio frame, and the position in a radio frame may be represented by a subframe index. The subframe index is any integer value in 0 to 9. A subframe whose subframe index number is M corresponds to an (M+1)th subframe in a radio frame. A slot may also be represented by a position in a radio frame, and the position in a radio frame may be represented by a slot index. The slot index is any integer value in 0 to 19. A slot whose slot index number is N corresponds to an (N+1)th slot in a radio frame. An OFDM symbol may be represented by a position in a subframe, or may be represented by a position in a slot. The position in a subframe may be represented by an OFDM symbol index, the OFDM symbol index is an any integer value in 0 to 13 or 0 to 11, and an OFDM symbol whose OFDM symbol index is K corresponds to a (K+1)th OFDM symbol in a subframe. The position in a slot may also be represented by an OFDM symbol index, the OFDM symbol index is any integer value in 0 to 6 or 0 to 5, and an OFDM symbol whose OFDM symbol index is L corresponds to an (L+1)th OFDM symbol in a slot.
