Scalable channel feedback for wireless communication

An apparatus for wireless communication, comprising:

• means for determining granularity of feedback of channel state information (CSI) for each of a plurality of cells, the granularity of feedback for each cell being selected based on quality of a communication channel between the cell and a user equipment (UE);
• and
• means for reporting CSI for each of the plurality of cells based on the granularity of feedback for the cell.

An apparatus for wireless communication, comprising:

• at least one processor configured to determine granularity of feedback of channel state information (CSI) for each of a plurality of cells, the granularity of feedback for each cell being selected based on quality of a communication channel between the cell and a user equipment (UE), and to report CSI for each of the plurality of cells based on the granularity of feedback for the cell.

A computer program product, comprising:

• a non-transitory computer-readable medium comprising:
• code for causing at least one computer to determine granularity of feedback of channel state information (CSI) for each of a plurality of cells, the granularity of feedback for each cell being selected based on quality of a communication channel between the cell and a user equipment (UE), and
• code for causing the at least one computer to report CSI for each of the plurality of cells based on the granularity of feedback for the cell.

A method for wireless communication, comprising:

• receiving channel state information (CSI) for a cell among a plurality of cells, the CSI for the cell being determined by a user equipment (UE) in accordance with granularity of feedback of CSI selected for the cell based on quality of a communication channel between the cell and the UE;
• and
• sending data transmission from the cell to the UE based on the received CSI, the data transmission being sent by at least one cell among the plurality of cells, the at least one cell including the cell.
