Abstract

In this work, based on current 5G New Radio (NR) SYNC/RACH slot structures, we focus on initial access (IA) techniques when the base stations (BSs) and the user equipments (UEs) are equipped with uniform planar array (UPA) antennas and without context information from macro BSs. With different omni/beam antennas and exhaustive/iterative search, we present five possible IA schemes: (i) BS omni/UE omni as a reference; (ii) Exhaustive Search 1; (iii) Exhaustive Search 2; (iv) Iterative Search 1; (iv) Iterative Search 2. Through simulations and comparisons, we demonstrate the comprehensive consideration of IA scheme selection with respect to coverage/SNRs, search delays and BS/UE antenna array settings.
