Method and apparatus for transceiving wireless signal in wireless communication system
摘要
說明書
In Table 1, D denotes a downlink subframe, U denotes an uplink subframe and S denotes a special subframe. The special subframe includes DwPTS (Downlink Pilot TimeSlot), GP (Guard Period), and UpPTS (Uplink Pilot TimeSlot). DwPTS is used for initial cell search, synchronization or channel estimation in a UE and UpPTS is used for channel estimation in a BS and uplink transmission synchronization in a UE. The GP eliminates UL interference caused by multi-path delay of a DL signal between a UL and a DL.
The radio frame structure is merely exemplary and the number of subframes included in the radio frame, the number of slots included in a subframe, and the number of symbols included in a slot can be vary.
