Method of transmitting uplink data in wireless communication system
A method of transmitting uplink data in a wireless communication system is provided. The method includes receiving an uplink grant and transmitting uplink data through a resource block which is indicated by the resource block index in a control region of a slot indicated by the slot indicator in the subframe.
1. A method of transmitting uplink data in a wireless communication system, carried in a user equipment (UE), the method comprising:
receiving an uplink grant from a base station (BS), the uplink grant comprising a resource allocation field and a slot indicator, the resource allocation field comprising a resource block index which is an index of a resource block selected among a plurality of resource blocks in a control region of a subframe, the slot indicator indicating one of two slots in the subframe; and
transmitting uplink data through a first resource block which is indicated by a resource block index in a slot indicated by the slot indicator in the subframe.
2. The method of claim 1 , wherein the second resource block which is indicated by a resource block index in the other slot of the two slots not indicated by the slot indicator in the subframe is punctured.
3. The method of claim 2 , wherein control information of other UE is transmitted through the second resource block.
4. The method of claim 1 , further comprising:
transmitting the uplink data through a second resource block in the other slot of the two slots not indicated by the slot indicator in the subframe.
5. The method of claim 4 , wherein the first resource block and the second resource block are different in a frequency domain.
6. The method of claim 4 , wherein the second resource block is indicated by the resource block index.
7. The method of claim 1 , further comprising:
receiving a boundary indicator from the BS, the boundary indicator indicating whether the resource block indicated by the resource block index belongs to the control region of the subframe.
8. An apparatus for a wireless communication, the apparatus comprising:
a signal generator configured to generate and transmit a radio signal; and
a processor coupled with the signal generator and configured to:
receive an uplink grant, the uplink grant comprising a resource allocation field and a slot indicator,
the resource allocation field comprising a resource block index which is an index of a resource block selected among a plurality of resource blocks in a control region of a subframe,
the slot indicator indicating one of two slots in the subframe; and
transmit data through a resource block which is indicated by a resource block index in a slot indicated by the slot indicator in the subframe.
