1. A method for wireless communication supporting carrier aggregation, the method comprising:
- monitoring a first search space and a second search space on a primary component carrier, to receive a scheduling assignment including information indicating a component carrier on which data is transmitted, wherein a scheduling assignment for the primary component carrier is received in the first search space, and a scheduling assignment for a secondary component carrier is received in the second search space;
transmitting the data on one of the primary component carrier and the secondary component carrier,wherein the first search space for the primary component carrier is different from the second search space for the secondary component carrier.

Abstract
Methods and apparatuses are described for wireless communication supporting carrier aggregation. The method includes monitoring, by a user equipment (UE), a downlink control channel in a first search space to receive first control information in the first search space; monitoring, by the UE, a downlink control channel in a second search space to receive second control information in the second search space; and receiving, by the UE, data on a first carrier based on the received first control information or on a second carrier based on the received second control information.
