Transmission of scheduling assignments in multiple operating bandwidths
First Claim
1. A method for wireless communication supporting carrier aggregation, the method comprising:
- monitoring, by a user equipment (UE), a downlink control channel in a first search space to receive first control information in a first set of control channel elements (CCEs) of the first search space;
monitoring, by the UE, a downlink control channel in a second search space to receive second control information in a second set of CCEs of the second search space, the second set of CCEs being determined from the first set of CCEs; 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.

Abstract
Methods and apparatuses are described for wireless communication supporting carrier aggregation. The method includes 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. The first search space for the primary component carrier is different from the second search space for the secondary component carrier.

4. A user equipment (UE) for wireless communication supporting carrier aggregation, the UE comprising:
-
a transceiver; and a controller coupled with the transceiver and configured to; monitor a downlink control channel in a first search space to receive first control information in a first set of control channel elements (CCEs) of the first search space, monitor a downlink control channel in a second search space to receive second control information in a second set of CCEs of the second search space, the second set of CCEs being determined from the first set of CCEs, and receive data on a first carrier based on the received first control information or on a second carrier based on the received second control information. - View Dependent Claims (5, 6, 18, 19, 20)

7. A method for wireless communication supporting carrier aggregation, the method comprising:
-
transmitting, by a base station, first control information for a user equipment (UE) on a downlink control channel corresponding to a first set of control channel elements (CCEs) of a first search space; transmitting, by the base station, second control information for the UE on a downlink control channel corresponding to a second set of CCEs of a second search space, the second set of CCEs being determined from the first set of CCEs; and transmitting, by the base station, data on a first carrier based on the first control information or on a second carrier based on the second control information. - View Dependent Claims (8, 9, 21, 22)
