Abstract: Techniques are disclosed relating to channel quality reporting for full-duplex (FD) wireless communications. In some embodiments an apparatus (e.g., a mobile device) is configured to receive a reference signal in a wireless communication and determine an effective signal to interference plus noise ratio (SINR) for FD communications based on a measured SINR of the reference signal and one or more self-interference cancelation levels. The apparatus may determine the one or more self-interference cancelation levels based on the transmit power of signals transmitted by the apparatus and residual power after SIC. The SIC levels may include both analog and digital SIC levels, which may be separately determined. One or more modulation and coding schemes may be determined based on the effective SINR. In some embodiments, multiple effective SINRs are determined for multiple different transmission modulation orders used by the apparatus.

Abstract: Techniques are disclosed relating to channel quality reporting for full-duplex (FD) wireless communications. In some embodiments an apparatus (e.g., a mobile device) is configured to receive a reference signal in a wireless communication and determine one or more signal quality indicators for FD communications based on a measured SINR of the reference signal and one or more self-interference cancelation levels. The apparatus may determine the one or more self-interference cancelation levels based on the transmit power of signals transmitted by the apparatus and residual power after SIC. The SIC levels may include both analog and digital SIC levels, which may be separately determined. One or more modulation and coding schemes may be determined based on the effective SINR.
