Abstract : We propose an optimal beamwidth selection strategy based on the trade-off between localization and communication performance in millimeter wave networks. With larger resources devoted to localization, we achieve a lower beam-selection error due to accurate position information, although the resulting limitation in communication resources reduces the user data rate. Conversely, to obtain a better rate performance the system needs to increase the allocation for communication, consequently increasing the probability of beam selection error. We characterize localization performance bounds and downlink average rate performance of a mmWave network and accordingly introduce a possible multi-service optimization policy. © 2018 IEEE.
