Samsung patents phone power saving using specific signal checks
Samsung describes a method for mobile devices to save battery while in idle or inactive modes. The phone receives specific reference signals from the base station only when a control message indicates they are available, allowing the device to adjust its timing and frequency without constant monitoring.
In the filing’s own words
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a terminal in a wireless communication system is provided. The method includes receiving, from a base station, a configuration information for at least one of a tracking reference signal (TRS) configuration or a channel state information-reference signal (CSI-RS) configuration, and receiving, from the base station, at least one of a TRS or a CSI-RS based on the configuration information. At least one of the TRS or the CSI-RS is received when the terminal is in an idle mode or an inactive mode.
What exactly they claim (claim 1)
1. A method performed by a terminal in a wireless communication system, the method comprising: receiving, from a base station, system information including one or more configurations of reference signal (RS) for tracking to be used in idle or inactive mode; receiving, from the base station, downlink control information (DCI) for paging early indication including a bitmap, wherein a bit of the bitmap is associated with availability of RS resources configured based on the one or more configurations of RS for tracking; receiving, from the base station, an RS for tracking based on the one or more configurations of RS for tracking and the bit of the bitmap; and performing time or frequency tracking based on the RS for tracking, wherein the system information includes information associated with a duration of the availability of the RS resources.
