Abstract

The requirements dictated by Sixth Generation (6G) to support Vehicle-to-Everything (V2X) communications together with the propagation drawbacks at high frequencies impose the use of highly directive beams. Conventional Beam Management (BM) approaches based on an exhaustive beam search are characterized by high training times and frequent link interruptions. To overcome these issues side information coming from sensors at both vehicular UE, e.g., Global Position System (GPS), and Base Station (BS), e.g., radar, side are integrated in the BM procedures. This paper shows pros and cons of the two approaches and propose a joint radar- and GPS-aided BM procedure that allows to reduce training time in typical urban scenario.
