Abstract

A WTRU may receive configuration information for channel state information (CSI) feedback and a first CSI reference signal (CSI-RS) transmission. The processor is configured to determine a first subset of beams associated with the first CSI-RS transmission and a second subset of beams associated with the first CSI-RS transmission. The first subset of beams is associated with: a longer validity time than a validity time of the second subset of beams, a lower beam range than a beam range of the second subset of beams, and/or a smaller difference between beam indices associated with consecutive beam domain reporting instances than a difference between beam indices associated with the second subset of beams. The processor may send one or more reports that include an indication of the first and second subset of beams and first and second parameters associated with the first and second subset of beams, respectively.
