Terminal Paging Signal Transmission for Power Saving State
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the context of 5G wireless communication systems, there is a need for efficient power saving techniques and methods to manage beam tracking and feedback operations, particularly for terminals operating in power saving states and using multiple antennas, to enhance communication efficiency and reduce power consumption.
Innovation Solution
The proposed solution involves a method where a base station transmits configuration information and reference signals for beam measurement to a terminal, allowing the terminal to report beam information in a single instance, and includes the use of new RNTI and UE-specific IDs for efficient paging and beam management, enabling the terminal to operate in a power saving state while maintaining quick network reconnection capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the terminal frequently wakes up to check paging signals, then the terminal can quickly respond to network calls, but the power consumption increases
Solution Approach 1:
The terminal implements discontinuous reception by waking up periodically at predetermined paging occasions to check for paging signals, rather than continuously monitoring. This periodic action allows the terminal to balance between quick response to network calls and power saving by sleeping between paging occasions.
Solution Approach 2:
The network configures the terminal with predetermined paging occasions and identification information in advance. The terminal uses this pre-configured information to efficiently determine when to wake up and check for paging signals, avoiding the need for continuous monitoring while ensuring quick response when paged.
2Reliability
If the terminal uses multiple antennas for beam tracking, then the communication reliability improves, but the device complexity increases
Solution Approach 1:
The terminal segments the beam tracking task by having different antennas independently track different beams. Each antenna element or subset can independently measure reference signals and report beam information, dividing the complex multi-antenna beam tracking into manageable independent segments.
Solution Approach 2:
The terminal combines beam tracking results from multiple antennas through unified beam management procedures. The network receives beam information from multiple antennas and performs unified beam determination, merging the individual antenna measurements into a coordinated multi-antenna beamforming solution.
