Providing a downlink control structure in a first carrier to indicate information in a second different carrier

An apparatus, comprising:

• a memory;
• and
• at least one processor in communication with the memory, wherein the at least one processor is configured to:
• monitor a physical downlink control channel (PDCCH) on an anchor carrier for a carrier pointer message;
• receive, in a first subframe, the carrier pointer message on the PDCCH of the anchor carrier, wherein the carrier pointer message includes a bitmap, wherein the bitmap includes indications for each of a set of non-anchor carriers, wherein the bitmap instructs the apparatus to turn on monitoring of PDCCHs of one or more non-anchor carriers of a set of non-anchor carriers starting in a second subframe;
• and
• monitor, in the second subframe, the PDCCH of the anchor carrier and PDCCHs of the one or more non-anchor carriers of the set of non-anchor carriers based on the bitmap, wherein there is at least a one subframe delay between the first subframe and the second subframe.

A mobile station, comprising:

• wireless communication circuitry, configured to perform wireless communication with at least a base station;
• and
• processing hardware coupled to the wireless communication circuitry, wherein the processing hardware is configured to operate with the wireless communication circuitry to:
• monitor a physical downlink control channel (PDCCH) on an anchor carrier for a carrier pointer message;
• receive, in a first subframe, the carrier pointer message on the PDCCH of the anchor carrier, wherein the carrier pointer message includes a bitmap, wherein the bitmap includes indications for each of a set of non-anchor carriers, wherein the bitmap instructs the mobile station to turn on monitoring of PDCCHs of one or more non-anchor carriers of a set of non-anchor carriers;
• and
• monitor, in second subframe, the PDCCH of the anchor carrier and PDCCHs of the one or more non-anchor carriers of the set of non-anchor carriers based on the bitmap, wherein there is at least a one subframe delay between the first subframe and the second subframe.
