Abstract
(EN)
The present application is at least directed to an apparatus on a network including a non-transitory memory including instructions stored thereon for beamforming training during an interval in the network. The apparatus also includes a processor, operably coupled to the non-transitory memory, capable of executing the instructions of receiving, from a new radio node, a beamforming training signal and beam identification for each of plural beams during the interval. The processor is also configured to execute the instructions of determining an optimal transmission beam of the new radio node based on the beamforming training signals of the plural beams. The processor is further configured to execute the instructions of transmitting, to the new radio node, a signal including a beam identification of the optimal transmission beam and an identification of the apparatus during the interval. The processor is further configured to execute the instructions of receiving, from the new radio node, an optimal transmission beam for the apparatus including a beam identification based upon a determination from the new radio during the interval.
