Channel quality reporting for different types of subframes
First Claim
Patent Images
1. A method for channel quality estimation in a wireless network, comprising:
- indicating, to a user equipment (UE), to perform a plurality of channel quality measurements for at least two subbands in a subframe;
receiving, from the UE, a first channel quality report including a first channel quality measurement of a first subband and a second channel quality report including a second channel quality measurement of a second subband;
determining separate channel quality measurements for a clean subframe and an unclean subframe based on the first and second channel quality reports;
receiving, from the UE, a third channel quality report including a third channel quality measurement of a third subband; and
determining a channel quality measurement for a third subframe type based on the third report.

Abstract
A method for determining channel quality estimates of two or more types of subframes, such as clean and unclean subframes, may be applicable to both legacy and newer user equipment. A first base station affects a channel quality measurement by either transmitting dummy signals over designed tones that correspond to a second base station, or by puncturing transmissions during designated tones that correspond to the second base station.
