Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing paging processes, particularly in scenarios involving UE subgroups, paging occasions, and beam directions, leading to suboptimal resource utilization and increased power consumption.
Innovation Solution
Implementing paging early indication (PEI) responses, where user equipment (UE) and network entities coordinate through configured PEI responses to optimize paging occasions and beam directions, enhancing communication efficiency and reducing power consumption.

Engineering Contradiction Analysis
1Productivity
If traditional paging processes are used without PEI responses, then the paging procedure is simpler to implement, but resource utilization is suboptimal and power consumption increases
Solution Approach 1:
The patent applies preliminary action by introducing PEI (Paging Early Indication) responses that are sent before the actual paging occasion. The network entity sends a PEI to indicate whether paging information will be transmitted in the upcoming paging occasion, allowing the UE to prepare accordingly. This preliminary indication mechanism enables more efficient resource allocation and power management while maintaining manageable system complexity through standardized signaling procedures.
2Use of energy by stationary object
If PEI responses are implemented to optimize paging occasions and beam directions, then power consumption is reduced, but the paging process becomes more complex
Solution Approach 1:
The patent implements feedback through the PEI response mechanism where the UE sends back its PEI response to the network entity. This feedback loop allows the network to optimize paging transmissions based on UE capabilities and conditions. The feedback mechanism enables dynamic adjustment of paging parameters including beam direction and paging occasion selection, resulting in reduced power consumption while managing complexity through established feedback protocols.
3Productivity
If PEI responses are configured for UE subgroups and beam directions, then paging efficiency improves, but configuration complexity increases
Solution Approach 1:
The patent applies segmentation by dividing UEs into subgroups and organizing paging operations into specific beam directions and paging occasions. The PEI response configuration is segmented across different UE subgroups, each with specific beam direction assignments. This segmentation allows the system to manage complexity by handling paging efficiency optimization in modular segments rather than attempting to optimize all UEs simultaneously, making the configuration process more manageable while improving overall paging efficiency.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, an indication that configures a paging early indication (PEI) response for one or more of: a UE subgroup; a paging occasion; or a beam direction. The UE may receive, from the network entity, a PEI. The UE may transmit, to the network entity, the PEI response based at least in part on the PEI and the indication that configures the PEI response. The UE may receive, from the network entity and during the paging occasion, a paging indication based at least in part on the PEI response. Numerous other aspects are described.
