Coordinated interference cancellation in wireless network

An apparatus comprising at least one processor and at least one memory including computer instructions, when executed by the at least one processor, cause the apparatus to:

• receive, by a user device, a first signal including a first user device-specific signal from a base station and one or more interfering signals, the first user device-specific signal being received based on a first modulation and coding scheme (MCS);
• determine, by the user device, whether the user device can perform interference cancellation for the one or more interfering signals;
• send, by the user device to the base station, an interference cancellation feedback message including at least, for each of the one or more interfering signals, an interference cancellation capability indication that indicates whether or not the user device can perform interference cancellation for the interfering signal;
• receive an updated MCS, wherein the updated MCS is based, at least in part, on the interference cancellation feedback message;
• and
• receive, by the user device based on the updated MCS, a second signal including at least a second user device-specific signal in which at least one of a signal muting or an interference cancellation is performed for at least one of the interfering signals.

A method comprising:

• receiving, by a victim base station, a first signal from a user device and one or more interfering signals, the first signal being received based on a first modulation and coding scheme (MCS);
• determining, by the victim base station, whether the victim base station can perform interference cancellation for the one or more interfering signals;
• sending, by the victim base station to one or more neighbor base stations, an interference cancellation signaling message including at least, for each of the one or more interfering signals, an interference cancellation capability indication that indicates whether or not the victim base station can perform interference cancellation for the interfering signal;
• determining an updated MCS;
• and
• receiving, by the victim base station based on the updated MCS, at least a second signal, in which at least one of a signal muting or an interference cancellation is performed for at least one of the interfering signals.

A method comprising:

• transmitting, by a victim base station to a user device based on a first modulation and coding scheme (MCS), a first user device-specific signal;
• receiving, by the victim base station from the user device, an interference cancellation feedback message including at least, for each of one or more interfering signals, an interference cancellation capability indication that indicates whether or not the user device can perform interference cancellation for the interfering signal;

• receiving, by the victim base station from one or more of the neighbor base stations in response to the interference cancellation signaling message, a muting response that indicates whether one or more of the interfering signals will be muted (turned Off) by a neighbor base station;
• determining an updated MCS based at least on the muting response;
• and
• sending the updated MCS to the user device.
