5G NR TRS/CSI-RS Signaling Aspects for Enhanced UE Power Saving - A simplified explanation of the abstract

This abstract first appeared for US patent application 18467192 titled '5G NR TRS/CSI-RS Signaling Aspects for Enhanced UE Power Saving

Simplified Explanation

The patent application describes a user equipment (UE) that receives a message from a network cell to release or suspend the current connection state and enter an inactive or idle state, while configuring the use of a tracking reference signal (TRS) or channel state information reference signal (CSI-RS) for error estimation during decoding of downlink control information.

• UE receives message to release or suspend RRC connected state
• Message includes TRS or CSI-RS configuration for inactive or idle state
• UE enters inactive or idle state and applies TRS or CSI-RS configuration for error estimation

Potential Applications

• Mobile communication systems
• Wireless networks
• Internet of Things (IoT) devices

Problems Solved

• Efficient management of network resources
• Improved error estimation for decoding downlink control information

Benefits

• Enhanced network performance
• Reduced interference
• Improved reliability of communication connections

Original Abstract Submitted

A user equipment (UE) configured to operate in a radio resource control (RRC) connected state with a network cell, receive an RRC message to release or suspend the RRC connected state, the RRC message including an indication for a tracking reference signal (TRS) or channel state information reference signal (CSI-RS) configuration to use during an RRC inactive or idle state, enter the RRC inactive or idle state and apply the TRS or CSI-RS configuration for performing timing and frequency error estimation for decoding downlink control information.
