1. An apparatus, comprising:

  • one or more processing elements including analog self-interference cancelation (SIC) circuitry and one or more digital SIC processing elements, wherein the one or more processing elements are configured to;

    receive a reference signal in a wireless communication; and

    determine an effective signal to interference plus noise ratio (SINR) for full-duplex (FD) communications, based on the reference signal, wherein the effective SINR for FD communications is based on;

    a measured SINR of the reference signal; and

    one or more measured self-interference cancelation (SIC) levels that include an analog SIC level generated by the analog SIC circuitry and a digital SIC level generated by the one or more digital SIC processing elements, wherein the analog SIC level is determined based on power of a wireless transmission by the apparatus and a measured residual power of the wireless transmission after analog self-interference cancelation.
