Method and apparatus for managing interference in full-duplex communication

摘要

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives an intended signal from a first wireless device operating in a full-duplex mode, receives an interfering signal from a second wireless device communicating with the first wireless device, and reduces an interference of the received intended signal caused by the interfering signal by projecting a matrix of the received intended signal onto a space associated with the interfering signal.

1. A method of wireless communication comprising:
receiving an intended signal from a first wireless device operating in a full-duplex mode; receiving an interfering signal from a second wireless device communicating with the first wireless device; determining a first channel gain with respect to the first wireless device and a second channel gain with respect to the second wireless device; determining a subspace based on the first channel gain and the second channel gain; and reducing an interference of the received intended signal caused by the interfering signal by projecting a matrix of the received intended signal onto a space associated with the interfering signal, wherein the space is the subspace, the subspace being configured to increase a signal to interference-plus-noise ratio (SINR), and wherein the subspace is defined as H*(p×ggH+σ2I)−1, where H is the first channel gain, p is a power of the interfering signal, g is the second channel gain, gH is a Hermite conjugate of g, I is an identity matrix, and σ2 is a variance of noise at a receiver.
