Millimeter-wave (mmWave) communications rely on directional transmissions toovercome severe path loss. Nevertheless, the use of narrow beams complicatesthe initial access procedure and increase the latency as the transmitter andreceiver beams should be aligned for a proper link establishment. In thispaper, we investigate the feasibility of random beamforming for the cell-searchphase of initial access. We develop a stochastic geometry framework to analyzethe performance in terms of detection failure probability and expected latencyof initial access as well as total data transmission. Meanwhile, we compare ourscheme with the widely used exhaustive search and iterative search schemes, inboth control plane and data plane. Our numerical results show that, compared tothe other two schemes, random beamforming can substantially reduce the latencyof initial access with comparable failure probability in dense networks. Weshow that the gain of the random beamforming is more prominent in lighttraffics and low-latency services. Our work demonstrates that developingcomplex cell-discovery algorithms may be unnecessary in dense mmWave networksand thus shed new lights on mmWave network design.
