In this paper, we study the beam management in mmWave network from a systematic perspective. First, instead of optimizing the network performance regarding the sum-rate, we improve the beam coverage to better support user mobility, which can further reduce the beam tracking overhead. Second, to compensate for the severe signal attenuation in mmWave band, we conFigure the beam so as to satisfy the user link outage probability constraint. Third, to reduce the interference among users, we consider the inter-beam interference from both main-lobe and side-lobe. We formulate our beam management scheme as a non-linear integer optimization problem, which typically has high computational complexity. By deliberately transforming it to a geometric optimization problem and designing the rounding method, we give an optimized feasible solution with low computational complexity. We verify the performance of our beam management scheme through simulation. Extensive simulation results demonstrate that our proposed algorithm can efficiently manage the beam in mmWave network.
