Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently configuring clustered paging frames within a DRX cycle, leading to increased signaling overhead, power consumption, and latency due to the need for explicit configuration updates.
Innovation Solution
A method for deriving a clustered paging configuration from a non-clustered configuration by reusing parameters, allowing the UE to identify initial paging frames and calculate clustered paging frames without additional signaling, thereby reducing power consumption and signaling overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If explicit configuration updates are used for clustered paging frames, then paging configuration flexibility is improved, but signaling overhead increases
Solution Approach 1:
The UE autonomously derives the clustered paging configuration by applying a clustering function to the received non-clustered configuration parameters. The network does not need to explicitly signal the clustered configuration, as the UE self-generates it using the received parameters (drx-Cycle, nB, pagingFrame, pagingOccasionOffset) and the clustering function, thereby eliminating redundant signaling while maintaining configuration flexibility
Solution Approach 2:
The clustered paging configuration is created as a derived copy of the non-clustered configuration. The UE receives the base configuration parameters and copies/transforms them into the clustered configuration format through the clustering function, avoiding the need for separate explicit configuration signaling
2Manufacturing precision
If explicit configuration updates are used for clustered paging frames, then paging configuration accuracy is improved, but power consumption increases
Solution Approach 1:
The UE utilizes the periodic DRX cycle structure to determine paging frame positions. By deriving clustered paging configurations based on the periodic non-clustered parameters and applying the clustering function, the UE maintains accurate paging configuration without needing continuous explicit updates, thereby reducing power consumption while preserving configuration accuracy
3Reliability
If explicit configuration updates are used for clustered paging frames, then configuration reliability is improved, but latency increases
Solution Approach 1:
The network provides the base non-clustered configuration parameters in advance, and the UE preliminarily derives the clustered configuration locally without waiting for explicit clustered configuration signaling. This preliminary local derivation reduces latency while maintaining reliability, as the UE has the configuration ready before it would otherwise be needed
4Ease of operation
If clustered paging frames are explicitly configured, then paging frame distribution control is improved, but device complexity increases
Solution Approach 1:
The UE performs self-service by automatically deriving the clustered paging frame distribution through the clustering function applied to the received non-clustered parameters. This self-derivation process maintains precise distribution control without requiring the UE to manually configure or interpret complex clustered configuration parameters, thereby reducing operational complexity

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a set of parameters for a first paging configuration, wherein the set of parameters indicate a discontinuous reception cycle, and wherein the set of parameters are associated with a set of paging frames having a first distribution in the discontinuous reception cycle. The UE may monitor for a paging message during a paging frame of a clustered set of paging frames according to a second paging configuration, wherein the second paging configuration is derived from the first paging configuration, and wherein the clustered set of paging frames have a second distribution, in the discontinuous reception cycle, different from the first distribution. Numerous other aspects are described.
