Abstract
The present application provides a method in which a terminal transmits or receives a signal to or from a base station in a wireless communication system. Particularly, the method comprises the steps of: receiving a control signal configured by a first number of time units from the base station; and transmitting or receiving a data signal configured by a second number of time units to or from the base station on the basis of the control signal, wherein the control signal includes an indicator relating to the second number.
Claims8
A method for transmitting uplink channels to a base station (BS) by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving, on a first subframe, a first uplink grant for transmitting, on a second subframe, a first transmission time interval (TTI) based uplink data channel;
- transmitting the first TTI based uplink data channel on the second subframe using the first uplink grant, if a second uplink grant for transmitting, on the second subframe, a second TTI based uplink data channel is not detected;
- and
- transmitting, on the second subframe, the second TTI based uplink data channel using the second uplink grant, if the second uplink grant is detected,
- wherein the second TTI is shorter than the first TTI.
A user equipment (UE) in a wireless communication system, the UE comprising:
- a radio frequency (RF) unit;
- and
- a processor connected with the RF unit,
- wherein the processor is configured to:
- receive, on a first subframe, a first uplink grant for transmitting, on a second subframe, a first transmission time interval (TTI) based uplink data channel;
- transmit the first TTI based uplink data channel on the second subframe using the first uplink grant if a second uplink grant for transmitting, on the second subframe, a second TTI based uplink data channel is not detected;
- and
- transmit, on the second subframe, the second TTI based uplink data channel using the second uplink grant, if the second uplink grant is detected,
- wherein the second TTI is shorter than the first TTI.
