Terminal-Group Channel and Signal Transceiving for RRC Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current NR R16 standard does not support power saving channel and signal transceiving in radio resource control-idle (RRC-idle) and radio resource control-inactive (RRC-inactive) states, leading to increased operation load and power consumption on terminals due to the direct application of RRC-connected state solutions.
Innovation Solution
A method and apparatus for configuring and transmitting power saving channels and signals to indicate the reception or transmission of specific terminal groups, allowing for reduced power consumption and operation load by dynamically controlling the transmission of signals such as paging, synchronization, and reference signals in RRC-idle and RRC-inactive states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the transceiving solution for the power saving channel and/or power saving signal in the RRC-connected state is directly applied to RRC-idle and RRC-inactive states, then the power saving channel and/or signal can be used for indicating terminal operations, but the operation load on the terminal side increases and causes unnecessary power consumption
Solution Approach 1:
The invention segments terminals into different terminal groups (first terminal group and second terminal group) based on their power saving requirements and operational states. Different power saving channels and/or signals are allocated to different terminal groups, allowing the network to selectively indicate operations only to relevant terminals rather than broadcasting to all terminals, thereby reducing overall terminal power consumption while maintaining reliable indication capability.
Solution Approach 2:
The invention implements partial action by selectively transmitting power saving channels and/or signals only to specific terminal groups when needed, rather than continuously transmitting to all terminals. The network determines whether to transmit based on whether there are operations to be indicated, avoiding unnecessary transmissions and reducing terminal power consumption while maintaining reliable indication when required.
2Adaptability or versatility
If the transceiving solution for the power saving channel and/or power saving signal in the RRC-connected state is directly applied to RRC-idle and RRC-inactive states, then the power saving channel and/or signal can bear three kinds of information, but it is impossible to determine what information the power saving channel and/or signal are required to bear in idle and inactive states
Solution Approach 1:
The invention segments the information bearing requirements into different categories for different terminal groups. The first terminal group receives power saving channels/signals indicating operations related to paging, synchronization, and channel state, while the second terminal group receives indications for different operations. This segmentation simplifies the information determination process by assigning specific information types to specific terminal groups based on their operational contexts.
Solution Approach 2:
The invention applies local quality by configuring different power saving channels and/or signals with different information bearing capabilities for different terminal groups. Each terminal group receives customized information indications suitable for its specific operational state and requirements, making the information determination straightforward and context-appropriate rather than requiring complex universal determination logic.
3Reliability
If the power saving channel and/or signal transceiving is configured for all terminals in RRC-idle and RRC-inactive states, then comprehensive coverage is achieved, but the operation load on the terminal side increases
Solution Approach 1:
The invention segments terminals into multiple groups and configures power saving channels and/or signals selectively for each group based on their specific needs. This allows comprehensive coverage of all terminals when necessary while avoiding unnecessary configuration for terminals that do not require it, thereby maintaining reliable indication coverage while preserving terminal operation efficiency.
Solution Approach 2:
The invention implements partial action by configuring power saving channel and/or signal transceiving only for terminal groups that require it, rather than universally configuring all terminals. The network determines which terminal groups need the power saving indications and configures them accordingly, achieving necessary coverage while minimizing operation load on terminals that do not require the functionality.
