  The millimeter wave (mmWave) communication has drawn intensive attention with
abundant band resources. In this paper, we consider the popular content
distribution (PCD) problem in the mmWave vehicular network. In order to offload
the communication burden of base stations (BSs), vehicle-to-vehicle (V2V)
communication is introduced into the PCD problem to transmit contents between
on-board units (OBUs) and improve the transmission efficiency. We propose a
full-duplex (FD) cooperative scheme based on coalition formation game, and the
utility function is provided based on the maximization of the number of
received contents. The contribution of each member in the coalition can be
transferable to its individual profit. While maximizing the number of received
contents in the fixed time, the cooperative scheme also ensures the individual
profit of each OBU in the coalition. We evaluate the proposed scheme by
extensive simulations in mmWave vehicular networks. Compared with other
existing schemes, the proposed scheme has superior performances on the number
of possessed contents and system fairness. Besides, the low complexity of the
proposed algorithm is demonstrated by the switch operation number and CPU time.
