A Novel Efficient Initial Access Method for 5G Millimeter Wave Communications Using Genetic Algorithm.

Initial Access (IA) in millimeter wave (mmWave) communications, i.e., the mechanism by which the Base Station (BS) and the User Equipment (UE) establish a directional communication link, is a challenging problem. A significant delay can be incurred when the BS and the UE try to find the appropriate beam alignment for obtaining a directional link, and solving this problem efficiently has become an ...
