Abstract

The use of directive antennas in frequency ranges above 10GHz is mandatory due to the high attenuation and other propagation phenomena that occur in these bands. As a result, initial user access to such cellular networks is slow as the base station and user are required to beamform before they can communicate. An alternative to make this process faster is by using user positioning information, but so far no work has considered the impact of geolocation errors on this process. In this paper, two new mechanisms aware of geolocation errors that explore a larger angular space to find better performing beam combinations are proposed.
