| Summary: | Massive multiple-input multiple-output can significantly increase the system capacity by allowing vehicle-to-infrastructure (V2I) and vehicle-to-vehicle (V2V) networks to share the radio resource pool, if the inter-network interference is constrained. However, in order to control the inter-network interference, it is necessary to exchange channel state information (CSI) between the V2I and V2V networks, which requires a huge amount of signaling resources. This paper proposes an one-bit signaling-based interference management scheme to reduce the signaling overhead while controlling the interference from the V2V network to the V2I network.
