Abstract

A user equipment (UE) is provided that includes a processor configured to transmit a preceding matrix index (PMI) using one of an assigned periodic PMI reporting resource that precisely aligns with the start of an on-duration of a discontinuous reception (DRX) operation mode of the UE and a first assigned periodic PMI reporting resource after the start of an on-duration of a discontinuous reception (DRX) operation mode of the UE.
