1. An apparatus configured to be employed in a UE (User Equipment), comprising:
a memory interface; and
processing circuitry configured to:
process a power saving signal associated with a drx-onDuration (Discontinuous Reception On Duration) occasion of a Connected mode DRX, wherein the power saving signal is received via a set of RBs (Resource Blocks) comprising a first plurality of RBs associated with a first precoder and a second plurality of RBs associated with a second precoder, wherein both the first plurality of RBs and the second plurality of RBs are within a configured set of time and frequency resources of the power saving signal; and
determine, based on the first plurality of RBs or the second plurality of RBs, a signal waveform of the power saving signal, or signaling content of the power saving signal, whether the power saving signal is a WUS (Wake Up Signal) or a GTS (Go To Sleep signal).
