Abstract

As a benefit of using highly directional beams in millimeter wave systems the downlink inter-cell interference (ICI) imposed on the users can be mitigated, provided that the beams of neighbor cells do not point towards the user. We exploit this by designing a protocol for network-coordinated time-domain beam scheduling. Specifically, every pair of neighboring cells maintains a beam-collision table for recording the pairs that may inflict ICI upon each other. Then, to avoid beam-collision, the two neighbor cells exchange the necessary information to avoid their simultaneous activation. More explicitly, our protocol
supports a distributed cell coordination method without requiring any information exchange between the user and the base station, once the beam collision table has been established. Furthermore, our theoretical analysis and numerical simulations demonstrate that the proposed protocol is capable of efficiently mitigating the ICI between the adjacent cells and hence improves the overall network performance.
