TRACKING REFERENCE SIGNALS FOR ENERGY SAVING MODES

Abstract

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, while in a connected mode, a control message indicating whether the UE is to use channel state information (CSI) reference signals (CSI-RSs) as tracking reference signals (TRSs) when the UE operates in an idle more or an inactive mode. The UE may transition to the idle more or the inactive mode and may perform, while in the idle more or the inactive mode, automatic gain control (AGC), time/frequency tracking, or both, using the CSI-RSs as the TRSs based on the control message indicating that the UE is to use the CSI-RSs as the TRSs. In some examples, the UE may perform the AGC, time/frequency tracking, or both, based on one or more CSI-RS resource occasions associated with the CSI-RSs.
