Improving carrier aggregation performance
First Claim
1. A method for carrier scheduling, comprising:
- scheduling a communication of control channel information from a low power node on a physical downlink control channel (PDCCH) over at least one of a first low power component carrier and a second low power component carrier;
identifying at each corresponding sub-frame of the first and second low power component carriers, the sub-frame having a lowest level of interference caused by a corresponding macro component carrier; and
selecting the identified sub-frame at each corresponding sub-frame of the first and second low power component carriers on which to transmit the control channel information on the PDCCH to a wireless device.

Abstract
A system and method for using carrier aggregation and enhanced inter-cell interference coordination in carrier scheduling is disclosed. The method comprises scheduling a communication of control channel information from at least one low power node on a physical downlink control channel (PDCCH) over at least one of a first low power component carrier and a second low power component carrier. A sub-frame having a lowest level of interference caused by a corresponding macro component carrier is identified at each corresponding subframe of the component carriers. The identified sub-frame is selected to transmit the control channel information on the PDCCH from the at least one low power node to a mobile wireless device.

7. A wireless system using carrier aggregation and enhanced inter-cell interference coordination, comprising:
-
a low power node configured to communicate with a wireless device via a first low power component carrier and a second low power component carrier using the carrier aggregation, wherein the first and second low power component carriers include light macro interference sub-frames associated with almost blank sub-frames in a first macro component carrier and a second macro component carrier, respectively; a cross carrier scheduling module configured to communicate with the low power node, wherein the cross carrier scheduling module is configured to schedule control channel information for the first low power component carrier for transmission on the second low power component carrier during light macro interference sub-frames of the second low power component carrier. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method for carrier scheduling, comprising:
-
receiving, at a user equipment (UE), a physical downlink control channel (PDCCH) monitoring pattern to identify, for each sub-frame, a component carrier on which the PDCCH will be monitored at the UE; receiving, at the UE, a first PDCCH monitoring pattern to identify, for each sub-frame, one of a first macro component carrier and a second macro component carrier, on which the PDCCH will be monitored at the UE; and receiving, at the UE, a second PDCCH monitoring pattern to identify, for each sub-frame, one of a first low power component carrier and a second low power component carrier, on which the PDCCH will be monitored at the UE. - View Dependent Claims (14, 15, 16, 17, 18, 19)
