Abstract
Given the increasing interest for future connected vehicles, the long term evolution (LTE) specifications are being enhanced by 3GPP to cope with the vehicle-to-everything (V2X) scenarios starting from the upcoming Release 14, which will include, among others, vehicle-to-vehicle (V2V) direct communications. Since the main service expected for connected vehicles is the cooperative awareness, in this work we aim at deriving the number of neighbors that can be managed by LTE-V2V. In addition to the normal half duplex (HD) radios, which strictly limit the granularity of resource allocation, advanced full duplex (FD) radios are also considered. Results show that LTE-V2V with HD radios is able to manage up to few tens of neighbors, whereas FD can increase this limit significantly at the expense of an increase of complexity.
