Abstract
Systems and method for establishing a connection between a vehicle and a base station are provided. The base station sectors are divided into subsector respectively associated with a narrowbeam antenna. To determine the vehicle location without the use of a complementary network, the base station and the vehicle may associate each subsector with a respective set of radio access preamble sequences. Accordingly, the location of the vehicle can be determined based on the particular radio access preamble sequence included in the synchronization messaging. Additionally or alternatively, the base station may be configured to sequentially activate the narrowbeam antennas to detect a which narrowbeam is active when the vehicle responds to a message communicated over the narrowbeams.
