Method and apparatus for multi-sTTI-based scheduling for transmitting and receiving data channel in LTE

Abstract:

Provided is a method of scheduling for improving the performance of data channel detection in order to provide URLLC services in the 3GPP LTE/LTE-A system. In particular, a method of a UE may be provided for transmitting an uplink data channel or receiving a downlink data channel. The method may include receiving repetitive transmission information for the uplink data channel or the downlink data channel from a base station, and receiving the downlink data channel from the base station or transmitting the uplink data channel to the base station, based on the repetitive transmission information. The repetitive transmission information indicates a number of repetitive transmissions for the uplink data channel or the downlink data channel, and the repetitive transmission is performed based on on a unit of a slot or a unit of a sub-slot.
