METHODS OF CHANNEL QUALITY INDICATION REPORTING WITH TYPE II CODEBOOK FOR HIGH VELOCITY

Abstract

Systems and methods are disclosed for Channel Quality Indicator (CQI) reporting. In one embodiment, a method performed by a User Equipment (UE) comprises receiving, from a network node, first signaling that indicates a precoding matrix duration in time domain and receiving, from the network node, second signaling that indicates a number of precoder matrix durations wherein each precoder matrix duration is associated with a precoder matrix. The method further comprises receiving, from the network node, third signaling that indicates one or more CQI resolutions in time domain for one or more CQIs. The method further comprises reporting, to the network node, Precoding Matric Indicator (PMI) for the number of precoder matrix durations and reporting, to the network node, one or more CQIs according to the indicated one or more CQI resolutions in time domain. In this manner, feedback of CQI is enabled for, e.g., high-velocity UEs.
