1. A user equipment (UE) for selecting beams in a wireless communication system, the UE comprising:
a transceiver; and
a processor operably connected to the transceiver, the processor configured to:
determine, based on a channel condition, whether to use an adaptive selection operation or a cycling selection operation to select a subset of beams from a plurality of beams for a beam measurement;
based on the channel condition being a first channel condition, use the adaptive selection operation to select, based at least in part on a location of a reference beam that is derived from past measurements associated with a plurality of beam patterns for measurement beams, the subset of beams from the plurality of beams for the beam measurement;
based on the channel condition being a second channel condition, use the cycling selection operation to select the subset of beams from the plurality of beams for the beam measurement, wherein a repetition of different subsets of the measurement beams from the plurality of beams is used in the cycling selection operation, wherein the first channel condition is different from the second channel condition;
perform the beam measurement on the selected subset of beams;
generate beam measurement information based on the beam measurement on the selected subset of beams; and
determine one or more of the plurality of beams to use for a wireless communication based on the beam measurement information.
