Title:
METHODS AND APPARATUS FOR UE POWER SAVING USING TRS AND CSIRS CONFIGURATIONS IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/158897
Kind Code:
A1
Abstract:
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.
