Transmission of scheduling assignments in multiple operating bandwidths
First Claim
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; and
receiving 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 the transmission of Scheduling Assignments (SAs) from a base station to User Equipments (UEs) for data reception in the downlink or data transmission in the uplink of a communication system. A method for wireless communication includes receiving a scheduling assignment in a search space on a primary component carrier, the scheduling assignment including information indicating a component carrier on which data is transmitted; and receiving the data on the indicated component carrier. The search space for the primary component carrier is different from a search space for a secondary component carrier.
