Systems and Methods to Receive CSI-RS/TRS Indication by Idle/Inactive Mode UEs for Improved Paging Reception - A simplified explanation of the abstract
This abstract first appeared for US patent application 17593746 titled 'Systems and Methods to Receive CSI-RS/TRS Indication by Idle/Inactive Mode UEs for Improved Paging Reception
Simplified Explanation
The abstract describes a method for wireless communication that allows a user device to efficiently receive and process information while in a reduced power state. The method involves the following steps:
- The user device receives resource information for receiving channel state information reference signal (CSI-RS) and tracking reference signal (TRS) while in a reduced power state.
- Based on the received resource information, the user device exits the reduced power state to receive the CSI-RS and TRS.
- The user device synchronizes with a base station using the received CSI-RS and TRS to receive a downlink control information message.
- The user device receives paging information in a first physical downlink shared channel (PDSCH) transmission based on the received downlink control information message.
- The user device determines whether there is paging information in the first PDSCH transmission for itself.
- If there is paging information, the user device initiates a Random Access Channel (RACH) procedure to establish a Radio Resource Control (RRC) connection.
- If there is no paging information, the user device returns to the reduced power state.
Potential applications of this technology include:
- Wireless communication systems and devices
- Internet of Things (IoT) devices
- Mobile devices and networks
Problems solved by this technology:
- Efficient power management for user devices in wireless communication systems
- Optimized reception and processing of information while in a reduced power state
- Minimizing unnecessary power consumption by only waking up the device when necessary
Benefits of this technology:
- Improved battery life for user devices
- Reduced power consumption and energy efficiency
- Enhanced performance and responsiveness of wireless communication systems
Original Abstract Submitted
An example method for wireless communication includes: receiving, by a user device in a reduced power state, resource information for receiving a channel state information reference signal (CSI-RS) and tracking reference signal (TRS); exiting the reduced power state to receive the CSI-RS and TRS, based on the resource information; synchronizing with a base station, based on the received CSI-RS and TRS, to receive a downlink control information message; receiving paging information in a first physical downlink shared channel (PDSCH) transmission based on the received downlink control information message; determining whether there is paging information in the first PDSCH transmission for the user device; starting a Random Access Channel (RACH) procedure to make a Radio Resource Control (RRC) connection, based on determining that there is paging information for the user device; and returning to the reduced power state, based on determining that there is not paging information for the user device.
