Carrier-Group Paging Coordination for Lower Network Energy Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing energy consumption of network devices in wireless networks, particularly in 5G and beyond systems, due to the deployment of more active antenna units, transceiver antenna arrays, higher data rates, and higher-frequency carriers, necessitates a solution to reduce energy consumption.
Innovation Solution
A communication method and apparatus that involves coordinating the sending and receiving of paging-related messages across a carrier group, utilizing a paging-related configuration to reduce the duration of sending and increase muting periods, thereby optimizing energy usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If more active antenna units and transceiver antenna arrays are deployed to support higher data rates and traffic requirements, then network capacity and data rate are improved, but energy consumption of network devices increases
Solution Approach 1:
The patent implements periodic sending of paging messages across multiple carriers in a coordinated manner, with defined muting periods between transmissions. This periodic action allows the network device to maintain paging functionality while reducing continuous transmission energy consumption, directly addressing the contradiction between network capacity maintenance and energy consumption reduction.
2Use of energy by moving object
If coordinated sending is implemented across multiple carriers to reduce sending duration, then energy consumption is reduced, but communication complexity increases
Solution Approach 1:
The patent segments the paging transmission across multiple carriers (first carrier, second carrier, third carrier) with distinct time-domain positions and muting periods. This segmentation allows coordinated sending to reduce overall energy consumption while distributing the complexity across manageable carrier segments rather than requiring complex centralized control.

AI summary
Communication methods and apparatuses are provided. An exemplary method includes a first communication apparatus receives a paging-related configuration sent by a second communication apparatus, where the paging-related configuration indicates paging-related configuration information of a carrier group including a plurality of carriers; and the first communication apparatus receives, on one or more carriers in the carrier group based on the paging-related configuration, a paging-related message sent by the second communication apparatus. This serves to implement coordinated reception on the plurality of carriers in the carrier group as well as to reduce the energy consumption of a network device.
