Feedback to enhance rate prediction with bursty interference

A method of wireless communication, comprising:

• transmitting a packet to a user equipment (UE), the packet having a first modulation and coding scheme (MCS);
• receiving information from the UE only if the UE fails to decode the packet, wherein the information comprises channel quality information (CQI) relating to an interference condition corresponding to time-frequency resources allocated for the transmitted packet, a data channel quality information (DCQI) report corresponding to time-frequency resource blocks on which data is allocated;
• optimizing the packet, based on the received information, to have a second MCS, the second MCS being different from the first MCS;
• and
• retransmitting the optimized packet to the UE.

An apparatus for wireless communication, comprising:

• means for receiving a first packet from a base station, the first packet having a first modulation and coding scheme (MCS);
• means for attempting to decode the first packet;
• means for determining information to provide to the base station only if the first packet fails to be decoded, wherein the information comprises channel quality information (CQI) relating to an interference condition corresponding to time-frequency resources allocated for the received first packet, and a data channel quality information (DCQI) report corresponding to time-frequency resource blocks on which data is allocated;
• means for sending the information to the base station;
• and
• means for receiving a second packet from the base station, the second packet being an optimized version of the first packet and having a second MCS, the second MCS is different from the first MCS and is determined based at least in part on the determined information provided to the base station.
