METHOD AND APPARATUS FOR SENDING CHANNEL STATE INFORMATION USING SUBFRAME - DEPENDENT CONTROL CHANNEL FORMAT
First Claim
1. A method for wireless communication, comprising:
- identifying a plurality of cells for which to report channel state information (CSI) by a user equipment (UE);
determining a plurality of control channel formats to use to report the CSI for the plurality of cells in a plurality of subframes; and
reporting the CSI for the plurality of cells in the plurality of subframes based on the plurality of control channel formats.

Abstract
Techniques for reporting channel state information (CSI) for multiple cells (e.g., carriers) using multiple control channel formats are disclosed. A user equipment (UE) may be configured for operation on a plurality of cells. The UE may be configured to periodically report CSI for the plurality of cells and may also report CSI whenever requested. The UE may be configured with a plurality of control channel formats for sending CSI and possibly other control information in different subframes. The plurality of control channel formats may be associated with at least two different capacities. The UE may report CSI for the plurality of cells in the plurality of subframes based on the plurality of control channel formats.
