Control signal transceiving method and apparatus for same
First Claim
1. A method for receiving control information by a user equipment (UE) in a wireless communication system in which a first type of carrier and a second type of carrier are aggregated, the method comprising:
- receiving grant information by the user equipment, the grant information used for signal transmission on the second type of carrier,wherein the grant information is received through the second type of carrier when the grant information comprises a first type of downlink control information (DCI) format, andwherein the grant information is received through the first type of carrier when the grant information comprises a second type of DCI format, the grant information comprising the second type of DCI format received through the first type of carrier when cross carrier scheduling is not configured for the UE and a cell-specific reference signal (CRS) is not transmitted on the second type of carrier at subframe timing for receiving the grant information.

Abstract
The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and an apparatus for receiving control information in a wireless communication system in which a first carrier type and a second carrier type are aggregated. The method comprises a step of receiving grant information for signal transmission on the second carrier type, wherein the grant information is received through the second carrier type if the grant information includes a first downlink control information (DCI) format, wherein the grant information is received through the first carrier type if the grant information includes a second DCI format.

8. A user equipment (UE) for receiving control information in a wireless communication system in which a first type of carrier and a second type of carrier are aggregated, the UE comprising:
-
a radio frequency (RF) unit; and a processor, that receives grant information through the RF unit, the grant information used for signal transmission on the second type of carrier, wherein the grant information is received through the second type of carrier when the grant information comprises a first type of downlink control information (DCI) format, and wherein the grant information is received through the first type of carrier when the grant information comprises a second type of DCI format, the grant information comprising the second type of DCI format received through the first type of carrier when cross carrier scheduling is not configured for the UE and a cell-specific reference signal (CRS) is not transmitted on the second type of carrier at subframe timing for receiving the grant information. - View Dependent Claims (9, 10, 11, 12, 13, 14)
