## Abstract

A method of transmitting data for uplink coverage for improvement of a wireless communication system by a terminal improving uplink data transmission reliability so as to be capable of successful data transmission. A method for transmitting and receiving a signal of a terminal in a time division wireless communication system of the present invention includes receiving a TTI bundling setting command from a base station, confirming whether a TTI bundling number is included in the TTI bundling setting command, determining the time when a signal is transmitted and received according to the TTI bundling number, when the TTI bundling number is included and determining the time when a signal is transmitted and received according to a preset TTI bundling number, when the TTI bundling number is not included.

## Claims

### Claim 1

A signal transmission/reception method of a terminal in a Time Division Duplexing (TDD) wireless communication system, the method comprising:
receiving a TTI bundling configuration command from a base station;
checking whether the TTI bundling configuration command includes a number of subframes for the TTI bundling;
determining, when the number of subframes for TTI bundling is included, signal transmission/reception timing according to the number of subframes for TTI bundling; and
determining, when the number of subframes for TTI bundling is not included, signal transmission/reception timing according to a predetermined number of subframes for TTI bundling.

### Claim 2 (depends on 1)

The method of claim 1, wherein the determining of the signal transmission/reception timing according to a predetermined number of subframes for TTI bundling comprises determining the signal transmission/reception timing based on the number of subframes which is fixed depending on TDD configuration number.

### Claim 3 (depends on 1)

The method of claim 1, wherein the determining of the signal transmission/reception timing according to a predetermined number of subframes for TTI bundling comprises determining the signal transmission/reception timing regardless of the number of subframes which is fixed depending on TDD configuration number.

### Claim 4 (depends on 1)

The method of claim 1, wherein the receiving of the TTI bundling configuration command comprises performing, when the TTI bundling configuration command is received after carrier aggregation is configured to the terminal, an RRC connection reestablishment procedure.

### Claim 5 (depends on 1)

The method of claim 1, wherein the receiving of the TTI bundling configuration command comprises receiving, when carrier aggregation is configured to the terminal, a carrier aggregation release command before the receipt of the TTI bundling configuration command.

### Claim 6

A terminal transmitting/receiving signals in a Time Division Duplexing (TDD) wireless communication system, the terminal comprising:
a transceiver which transmits and receives data and signals to and from a base station; and
a control unit which receives a TTI bundling configuration command from a base station, checks whether the TTI bundling configuration command includes a number of subframes for the TTI bundling, determines, when the number of subframes for TTI bundling is included, signal transmission/reception timing according to the number of subframes for TTI bundling, and determines, when the number of subframes for TTI bundling is not included, signal transmission/reception timing according to a predetermined number of subframes for TTI bundling.

### Claim 7 (depends on 6)

The terminal of claim 6, wherein the control unit determines the signal transmission/reception timing based on the number of subframes which is fixed depending on TDD configuration number.

### Claim 8 (depends on 6)

The terminal of claim 6, wherein the control unit determines the signal transmission/reception timing regardless of the number of subframes which is fixed depending on TDD configuration number.

### Claim 9 (depends on 6)

The terminal of claim 6, wherein the control unit performs, when the TTI bundling configuration command is received after carrier aggregation is configured to the terminal, an RRC connection reestablishment procedure.

### Claim 10 (depends on 6)

The terminal of claim 6, wherein the control unit receives, when carrier aggregation is configured to the terminal, a carrier aggregation release command before the receipt of the TTI bundling configuration command.
