5G Base Station Paging via Multi-Beam Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G communication systems, especially when using multi-beam antennas, transmitting paging signals to terminals in idle mode is inefficient due to power limitations and interference, requiring multiple time slots, which increases power consumption and delays.
Innovation Solution
A method where a base station configures and transmits paging signals through multiple time slots corresponding to each beam, allowing simultaneous transmission of paging messages across all beams, reducing the need for sequential transmission and optimizing power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If paging signals are transmitted sequentially through all beam antennas, then transmission power limitation and interference suppression are satisfied, but multiple time slots are required increasing latency and power consumption
Solution Approach 1:
The patent segments the paging transmission process by dividing the beam antenna set into multiple groups, where each group transmits paging signals in dedicated time slots. This segmentation allows parallel transmission across groups while maintaining power limitations within each beam, thus reducing overall latency compared to sequential transmission of all beams.
Solution Approach 2:
The patent introduces a group dimension to the beam transmission structure, organizing beams into multiple groups that can transmit simultaneously. This dimensional organization transforms the single-queue sequential transmission into a multi-queue parallel transmission system, reducing time loss while managing power constraints.
2Reliability
If paging signals are transmitted sequentially through all beam antennas, then transmission power limitation and interference suppression are satisfied, but multiple time slots are required increasing power consumption
Solution Approach 1:
By segmenting beams into groups that transmit in parallel time slots, the total transmission duration is reduced. Since power consumption is proportional to transmission time, this segmentation directly reduces overall power consumption while maintaining reliable delivery through multiple beam groups.
Solution Approach 2:
The patent enables continuous useful action by having multiple beam groups transmit paging signals simultaneously in different time slots rather than waiting for sequential completion. This parallel continuity reduces the total time paging signals remain in transit, thereby reducing overall power consumption.
3Loss of time
If all beam antennas transmit paging signals simultaneously, then transmission time is reduced, but transmission power limitation and interference between antennas cannot be satisfied
Solution Approach 1:
The patent segments the beam antenna set into multiple groups, assigning each group to specific time slots for transmission. This segmentation spatially and temporally separates simultaneous transmissions, reducing interference between antennas while still achieving parallel transmission across groups to minimize latency.
4Reliability
If paging signals are transmitted through multiple time slots, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent manages complexity by segmenting beams into groups with systematic time slot assignments. This structured segmentation provides a clear framework for configuration and management, making the multi-time-slot system more tractable than arbitrary complex scheduling while maintaining reliability through multiple transmission opportunities.
