- Abstract
- The random access (RA) technique is a key procedure in cellular networks but the overall duration of this technique in millimeter-wave (mm-wave) cellular systems with directional beams is very long because RA preambles (RAPs) should be transmitted in all directions of Tx and Rx beams. In this paper, two different types of preambles (RAP-1 and RAP-2) are proposed to reduce the processing time in the RA stage. In simulation, it is shown that the RAP-2 is suitable for RA in mm wave cellular systems with directional beams because of the smaller processing time and high detection probability in multi-user environments.
