1. A base station, comprising:
- wireless communication circuitry, configured to perform wireless communication with at least a mobile station; and
processing hardware coupled to the wireless communication circuitry, wherein the processing hardware is configured to operate with the wireless communication circuitry to;
transmit, to a mobile station, control information in resource blocks (RBs) of a physical downlink shared channel region on a first component carrier among a plurality of component carriers, wherein the plurality of component carriers comprises the first component carrier and a second component carrier, wherein the physical downlink shared channel region is located within orthogonal frequency division multiplexing (OFDM) symbols following the physical downlink control channel region in a subframe, wherein the second component carrier is different than the first component carrier, wherein the control information indicates a resource assignment for the mobile station on the second component carrier, and wherein the second component carrier is identified in the control information of the first component carrier by a component carrier number; and
communicate with the mobile station using the control information of the first component carrier and the resource assignment on the second component carrier.

Abstract
A mobile station receives a downlink control structure in a first carrier, where the downlink control structure indicates that control information for the mobile station is on a second, different carrier. The mobile station decodes the control information in the second carrier, where the control information specifies resource allocation of a wireless link for the mobile station. More specifically, according to some implementations, the control channel in the first carrier specifies the resource allocation for an extended control channel in the second carrier, where the extended control channel specifies the resource allocation for traffic data of a wireless link for the mobile station.
