We propose a novel analytical framework for evaluating the coverageperformance of a millimeter wave (mmWave) cellular network where idle userequipments (UEs) act as relays. In this network, the base station (BS) adoptseither the direct mode to transmit to the destination UE, or the relay mode ifthe direct mode fails, where the BS transmits to the relay UE and then therelay UE transmits to the destination UE. To address the drastic rotationalmovements of destination UEs in practice, we propose to adopt selectioncombining at destination UEs. New expression is derived for thesignal-to-interference-plus-noise ratio (SINR) coverage probability of thenetwork. Using numerical results, we first demonstrate the accuracy of our newexpression. Then we show that ignoring spatial correlation, which has beencommonly adopted in the literature, leads to severe overestimation of the SINRcoverage probability. Furthermore, we show that introducing relays into ammWave cellular network vastly improves the coverage performance. In addition,we show that the optimal BS density maximizing the SINR coverage probabilitycan be determined by using our analysis.
