Methods and apparatus for blind interference decrease/cancellation techniques

An apparatus for wireless communication, comprising:

• means for obtaining, at an eNodeB (eNB), one or more semi-static parameters identifying at least one neighboring eNB and an interfering UE, wherein the one or more semi-static parameters includes at least one of an eNB cell identifier (ID), a network identifier of the interfering UE, a resource ID of the interfering UE;
• means for determining, at the eNB, one or more unknown parameters, wherein the one or more unknown parameters includes one or more of a payload size, the network identifier of the UE, the resource ID of the interfering UE, whether the interfering UE is sending a control channel quality indicator (CQI) in a subframe, or a cyclic shift index per localized frequency division multiplexing symbol;
• and
• means for reducing signal interference from a signal generated by the interfering UE, at the eNB, by applying a blind interference reduction scheme based on the one or more unknown parameters that are determined.

A non-transitory computer-readable medium storing computer executable code for wireless communication, comprising code for:

• obtaining, at an eNodeB (eNB), one or more semi-static parameters identifying at least one neighboring eNB and an interfering user equipment (UE), wherein the one or more semi-static parameters includes at least one of an eNB cell identifier (ID), a network identifier of the interfering UE, a resource ID of the interfering UE;
• determining, at the eNB, one or more unknown parameters, wherein the one or more unknown parameters includes one or more of a payload size, the network identifier of the UE, the resource ID of the interfering UE, whether the interfering UE is sending a control channel quality indicator (CQI) in a subframe, or a cyclic shift index per localized frequency division multiplexing symbol;
• and
• reducing signal interference from a signal generated by the interfering UE, at the eNB, by applying a blind interference reduction based on the one or more unknown parameters that are determined.

An apparatus for wireless communication, comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• obtain, at an eNodeB (eNB), one or more semi-static parameters identifying at least one neighboring eNB and an interfering user equipment (UE), wherein the one or more semi-static parameters includes at least one of an eNB cell identifier (ID), a network identifier of the interfering UE, a resource ID of the interfering UE;
• determine, at the eNB, one or more unknown parameters, wherein the one or more unknown parameters includes one or more of a payload size, the network identifier of the UE, the resource ID of the interfering UE, whether the interfering UE is sending a control channel quality indicator (CQI) in a subframe, or a cyclic shift index per localized frequency division multiplexing symbol;
• and
• apply, at the eNB, a blind interference reduction scheme to reduce a signal from the interfering UE based on the one or more unknown parameters that are determined.
