Coordinated beamforming scaling conjecture for MISO cellular networks

Let $N_t(\lambda)$ be the number of transmit antennas in a MISO cellular network with a physically feasible path loss model. Suppose coordinated beamforming perfectly cancels the interference from the closest $N_t(\lambda)-1$ interfering base stations. Coordinated beamforming scaling conjecture. The mean SINR scales as $\frac{N_t(\lambda)}{\lambda}$ and the mean ASE scales as

$$\lambda \log_2\left(1+\frac{N_t(\lambda)}{\lambda}\right).$$

The conjecture formalizes the preceding analytical and simulation evidence that canceling the closest in-cluster interferers does not improve the asymptotic scaling laws in the ultradense regime; no resolution is supplied.
