Beam-Specific I-DRX Configuration for Wireless Resource Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in managing idle discontinuous reception (I-DRX) configurations, particularly in non-uniformly distributed user equipment (UE) scenarios where some beams experience higher traffic loads, leading to uneven resource allocation and increased energy consumption.
Innovation Solution
Implementing beam-specific I-DRX configurations, where the network entity indicates I-DRX settings for each beam or subset of beams, allowing UEs to receive paging occasions accordingly, and dynamically updating these configurations via paging error indication messages to optimize resource utilization and reduce energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single I-DRX configuration is applied to all beams, then device complexity is reduced and ease of operation is improved, but resource utilization efficiency deteriorates and energy consumption increases due to non-uniform traffic distribution
Solution Approach 1:
The patent segments the unified I-DRX configuration into beam-specific configurations. Each beam can now have its own I-DRX parameters (drx-IdleCycle, drx-InactiveCycle, drx-RetransmissionTimer) tailored to its traffic characteristics, allowing high-traffic beams to use shorter cycles for responsiveness while low-traffic beams use longer cycles for energy saving.
Solution Approach 2:
The patent applies local quality by making I-DRX configuration properties specific to each beam rather than uniform across all beams. The network entity configures different I-DRX parameters for different beams based on their individual traffic loads and characteristics, optimizing performance locally for each beam while managing overall system resources efficiently.
2Productivity
If beam-specific I-DRX configurations are implemented, then resource utilization efficiency is improved and energy consumption is reduced, but device complexity and configuration management difficulty increase
Solution Approach 1:
The patent implements self-service by enabling UEs to autonomously determine which I-DRX configuration to apply based on beam identification information received in system information or paging messages. The UE automatically associates the current beam's identifier with the corresponding I-DRX parameters and applies the correct configuration without requiring complex manual configuration or network-controlled switching.
Solution Approach 2:
The patent applies preliminary action by pre-configuring multiple beam-specific I-DRX configurations in the network entity before operation. Each beam's I-DRX parameters are prepared in advance and stored, allowing the network to quickly provide the appropriate configuration to UEs based on which beam they are currently receiving, eliminating the need for real-time configuration computation.
3Adaptability or versatility
If I-DRX configuration is updated dynamically via paging error indication messages, then adaptability to changing traffic patterns is improved, but signaling overhead and processing complexity increase
Solution Approach 1:
The patent implements feedback by using paging error indication messages as a feedback mechanism. When the network detects that a UE has missed a paging occasion or when traffic patterns change, it sends a paging error indication that triggers the UE to retrieve updated system information containing revised I-DRX configurations, allowing the system to adapt to changing conditions based on actual performance feedback.
Solution Approach 2:
The patent applies periodic action by scheduling periodic updates of I-DRX configurations through system information broadcasts. The network entity periodically refreshes the I-DRX configuration parameters in system information blocks, and UEs periodically monitor for these updates, creating a rhythmic update pattern that balances adaptability with signaling overhead management.

AI summary
Methods, systems, and devices for wireless communications are described. Idle discontinuous reception (I-DRX) configurations may be managed on a per beam or a per subset of beams basis. The network may indicate, via system information, the I-DRX configuration for a given beam or subset of beams. A user equipment (UE) in an idle mode may receive paging occasions via the given beam in accordance with the indicated I-DRX configuration for that beam. In some examples, system information may indicate a list of beams and corresponding I-DRX configurations for each beam in the list of beams. In some examples, system information may indicate the I-DRX configuration for the beam on which the system information is transmitted. If a UE changes beams, the UE may receive system information via the new beam that indicates an I-DRX configuration for the new beam before applying the I-DRX configuration to the new beam.
