Abstract
Methods and apparatuses in a wireless communication system. A method of operating a BS includes: receiving a first measurement report indicating information about at least first and second wide beams in a set of wide beams for a beam selection, the first measurement report generated based on measurement of a first set of child narrow beams of the first wide beam; determining whether a condition is detected for requesting measurement of a second set of child narrow beams of a second wide beam in the set of wide beams; determining to request the UE to measure the second set of child narrow beams of the second wide beam and; selecting a child narrow beam for use from one of the first set of child narrow beams and the second set of child narrow beams; and selecting the child narrow beam for use from the first set of child narrow beams.
