Method for transmitting and receiving uplink data in wireless communication system and device for same
First Claim
1. A method of transmitting and receiving, by a user equipment, uplink (UL) data in a wireless communication system, the method comprising:
- receiving a first UL grant from an eNodeB;
transmitting first UL data to the eNodeB based on the first uplink grant;
receiving an HARQ response of the first uplink data from the eNodeB;
transmitting second uplink data to the eNodeB using retransmission resources allocated for retransmission of the first uplink data; and
transmitting control information indicating whether the second uplink data is retransmission data of the first uplink data or new data generated due to a specific event to the eNodeB through physical uplink control channel (PUCCH) resources;
receiving scheduling request (SR) transmission resources for transmitting SR information from the eNodeB,wherein the control information is transmitted to the eNodeB through the SR transmission resources.

Abstract
The present description provides a method for transmitting and receiving uplink (UL) data in a wireless communication system. A method performed by a terminal comprises: receiving a first uplink grant from a base station; transmitting, based on the first uplink grant, first uplink data to the base station; receiving an HARQ response to the first uplink data from the base station; transmitting second uplink data to the base station by means of retransmission resources allocated for the retransmission of the first uplink data; and transmitting, to the base station, the control information, which indicates whether the second uplink data is retransmission data of the first uplink data or new data generated by means of a particular event, by means of physical uplink control channel (PUCCH) resources.
