Abstract

A method for transmitting data for a half-duplex device in a wireless communication system is provided. The half-duplex device receives first downlink control information from a base station in a first subframe. The half-duplex device transmits uplink data to the base station in a second subframe. The first downlink control information includes a resource through which the uplink data is transmitted and information on the second subframe.

First claim

What is claimed is:

1 . A method for transmitting data by a half-duplex device in a wireless communication system, the method comprising:
receiving, by the half-duplex device, first downlink (DL) control information from a base station in a first subframe; and transmitting, by the half-duplex device, uplink data to the base station in a second subframe, wherein the first DL control information comprises information about resources and the second subframe in which the uplink data is transmitted.

2 . The method of claim 1 , wherein the second subframe is indicated by an offset value based on an index of the first subframe.

3 . The method of claim 1 , wherein the second subframe is spaced apart from the first subframe at an interval of 4 ms or 5 ms.

4 . The method of claim 1 , wherein the second subframe is spaced apart from the first subframe at an interval of 4 ms, 5 ms, 6 ms, or 7 ms.

5 . The method of claim 1 , further comprising:
receiving, by the half-duplex device, a retransmission request for the uplink data from the base station in a third subframe; and retransmitting, by the half-duplex device, the uplink data to the base station in a fourth subframe, wherein the retransmission request comprises information about resources in which the uplink data is retransmitted.

6 . The method of claim 1 , further comprising:
receiving, by the half-duplex device, a retransmission request for the uplink data from the base station in a third subframe; and retransmitting, by the half-duplex device, the uplink data to the base station in a fourth subframe, wherein the retransmission request comprises information about the fourth subframe.

7 . The method of claim 6 , wherein the fourth subframe is indicated by an offset value based on an index of the third subframe.

8 . The method of claim 6 , wherein the fourth subframe is spaced apart from the third subframe at an interval of 4 ms or 5 ms.

9 . The method of claim 6 , wherein the fourth subframe is spaced apart from the third subframe at an interval of 4 ms, 5 ms, 6 ms, or 7 ms.

10 . The method of claim 1 , wherein the half-duplex device supports a bandwidth of 1.4 MHz.

11 . A half-duplex device in a wireless communication system, the device comprising:
a Radio Frequency (RF) unit configured to transmit and receive radio signals; and a processor connected to the RF unit and configured to: receive first downlink (DL) control information from a base station in a first subframe; and transmit uplink data to the base station in a second subframe, wherein the first DL control information comprises information about resources and the second subframe in which the uplink data is transmitted.

12 . The half-duplex device of claim 11 , wherein the second subframe is indicated by an offset value based on an index of the first subframe.

13 . The half-duplex device of claim 11 , wherein the processor is configured to:
receive a retransmission request for the uplink data from the base station in a third subframe; and retransmit the uplink data to the base station in a fourth subframe, wherein the retransmission request comprises information about resources in which the uplink data is retransmitted.

14 . The half-duplex device of claim 11 , wherein the processor is configured to:
receive a retransmission request for the uplink data from the base station in a third subframe; and retransmit the uplink data to the base station in a fourth subframe, wherein the retransmission request comprises information about the fourth subframe.

15 . The half-duplex device of claim 14 , wherein the fourth subframe is indicated by an offset value based on an index of the third subframe.
