## Abstract

The present application discloses a method for transmitting, by a base station, downlink control information to a terminal in a wireless communication system. More particularly, the method comprises the steps of: allocating, to a transmission resource, the downlink control information for the terminal; and transmitting, to the terminal, the downlink control information using the transmission resource. the downlink control information for the terminal comprises: a downlink grant; and an uplink grant, wherein the downlink grant is allocated to one of first and second slots of a subframe of the transmission resource, and the uplink grant is allocated to at least one of first and second slots of a subframe of the transmission resource.

## Claims

### Claim 1

A method of transmitting downlink control information to a user equipment at an eNode B in a wireless communication system, comprising:
allocating the downlink control information for the user equipment to a transmission resource; and
transmitting the downlink control information to the user equipment using the transmission resource,
wherein the downlink control information for the user equipment comprises a downlink grant and an uplink grant, wherein the downlink grant is allocated to either a first slot or a second slot of a subframe among the transmission resource, wherein the uplink grant is allocated to at least one of a first slot and a second slot of a subframe among the transmission resource.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the downlink grant is allocated to the first slot of the subframe only among the transmission resource.

### Claim 3 (depends on 1)

The method according to claim 1, wherein the transmission resource corresponds to a data region of the subframe.

### Claim 4 (depends on 1)

The method according to claim 1, wherein data information for the user equipment is allocated to at least one of a first slot and a second slot of a subframe among the transmission resource.

### Claim 5

An eNode B device in a wireless communication system, comprising:
a processor configured to allocate downlink control information for the user equipment to a transmission resource; and
a radio communication module configured to transmit the downlink control information to the user equipment using the transmission resource,
wherein the downlink control information for the user equipment comprises a downlink grant and an uplink grant, wherein the processor is configured to allocate the downlink grant to either a first slot or a second slot of a subframe among the transmission resource, wherein the processor is configured to allocate the uplink grant to at least one of a first slot and a second slot of a subframe among the transmission resource.

### Claim 6 (depends on 5)

The eNode B device according to claim 5, wherein the processor is configured to allocate the downlink grant to the first slot of the subframe only among the transmission resource.

### Claim 7 (depends on 5)

The eNode B device according to claim 5, wherein the transmission resource corresponds to a data region of the subframe.

### Claim 8 (depends on 5)

The eNode B device according to claim 5, wherein the processor is configured to allocate data information for the user equipment to at least one of a first slot and a second slot of a subframe among the transmission resource.
