Abstract: Techniques for compensating for self-induced interference in a small cell base station are provided. The techniques include detecting control signals from a neighboring base station associated with a wireless communication network, the control signals being transmitted by the neighboring base station at predetermined intervals, and compensating for self-induced interference caused by a transmitter of the small cell base station transmitting during the predetermined intervals in which control signals are received from the neighboring base station and the transmitter of the small cell base station is transmitting data.

Abstract: Various aspects described herein relate to interference cancellation. A received signal is received at a receiver chain, where the received signal is interfered by an aggressor signal transmitted using a transmitter chain. In a second portion of a time interval, one or more cancellation coefficients can be updated based on a measurement made in a first portion of the time interval, where the time interval can be within a protocol time interval of a protocol used by the transmitter chain. Based on the one or more updated cancellation coefficients, interference cancellation is performed to cancel interference of the aggressor signal from the received signal.

Abstract: Various aspects described herein relate to providing analog interference cancellation using digitally computed coefficients. An aggressor signal can be obtained from a transmitter chain of a radio frequency (RF) front end. A digital representation of the aggressor signal can be generated, and cancellation coefficients can be estimated for the digital representation of the aggressor signal. An analog cancellation signal can be generated based at least in part the cancellation coefficients and the digital representation of the aggressor signal. The analog cancellation signal can be added to a victim signal in a receiver chain of the RF front end to cancel interference to the victim signal from the aggressor signal.

Abstract: Various aspects described herein relate to providing analog interference cancelation in a shared antenna. A plurality of signals can be obtained at a plurality of reference points in a transmitter chain of a shared antenna. At least one reference point of the plurality of reference points from which to generate a cancelation signal and/or at least one injection point for injecting the cancelation signal can be selected based at least in part on expected analog interference cancelation metrics related to each of the plurality of reference points and/or the at least one injection point. The cancelation signal can be generated based at least in part on the at least one reference point and/or injection point. The cancelation signal can be injected in the injection point at a receiver chain of the shared antenna to cancel interference from signals generated at the transmitter chain of the shared antenna.
