Low-frequency assisted methods for beamforming, timing and frequency offset in mm-wave access systems
A method, an apparatus, and a computer program product for operating a user equipment (UE) are provided. The apparatus determines a first set of beamforming directions for communication with a base station (BS) in a first network, monitors for beams in a second set of beamforming directions for communication with a millimeter wave base station (mmW-BS) based on the determined first set of beamforming directions, where the second set of beamforming directions includes the first set of beamforming directions, and where the mmW-BS is in a second network having a higher carrier frequency than the first network, and establishes a communication link with the mmW-BS based on a beamforming direction in the second set of beamforming directions.
