METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING USING REDUCED TRANSMISSION TIME INTERVAL IN WIRELESS CELLULAR COMMUNICATION SYSTEM

摘要

The present invention relates to a wireless communication system, and especially to a method and an apparatus for operating transmissions of a downlink and uplink control channel in a system supporting transmission and reception to/from a transmission time interval that is shorter than 1 ms. Specifically, a method is provided for defining the physical channels that are required when the transmission time interval is shorter than 1 ms, especially when a TTI has a length of 1 OFDM symbol, for allocating resources and for mapping to a resource block.
