This paper studies the signal-to-interference ratio (SIR) meta distribution (MD) for multi-antenna multi-user networks with interference nulling (IN) considered. Since it is difficult to calculate the expression for the SIR MD, we resort to a tight upper bound on the conditional success probability (CSP) and obtain its first moment and second moment; with further utilizing the beta distribution, we obtain an approximation on the SIR MD. With numerical simulations, the tightness of this expression is verified and the effects of system design parameters on the network performance from the perspectives of the distribution of individual link reliability are revealed.

摘要

This paper studies the signal-to-interference ratio (SIR) meta distribution (MD) for multi-antenna multi-user networks with interference nulling (IN) considered. Since it is difficult to calculate the expression for the SIR MD, we resort to a tight upper bound on the conditional success probability (CSP) and obtain its first moment and second moment; with further utilizing the beta distribution, we obtain an approximation on the SIR MD. With numerical simulations, the tightness of this expression is verified and the effects of system design parameters on the network performance from the perspectives of the distribution of individual link reliability are revealed.
