| description | Millimeter wave (mmWave) communication is expected to play an important role
in next generation cellular networks, aiming to cope with the bandwidth
shortage affecting conventional wireless carriers. Using side-information has
been proposed as a potential approach to accelerate beam selection in mmWave
massive MIMO (m-MIMO) communications. However, in practice, such information is
not error-free, leading to performance degradation. In the multi-user case, a
wrong beam choice might result in irreducible inter-user interference at the
base station (BS) side. In this paper, we consider location-aided precoder
design in a mmWave uplink scenario with multiple users (UEs). Assuming the
existence of direct device-to-device (D2D) links, we propose a decentralized
coordination mechanism for robust fast beam selection. The algorithm allows for
improved treatment of interference at the BS side and in turn leads to greater
spectral efficiencies. |
