Beam Timing Coordination for Faster Wireless Cell Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cell handover technologies in wireless communication systems experience prolonged handover times due to varying requirements for frequency adjustments and beam changes across different scenarios, lacking a unified solution.
Innovation Solution
Implementing methods and apparatuses for information transmission that utilize beam application time information and measurement results to optimize handover processes, prioritizing certain measurement reports, and adjusting beam application times based on specific scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the terminal adjusts frequency range and beam after receiving handover signaling, then handover accuracy is improved, but handover time increases
Solution Approach 1:
The patent applies preliminary action by having the terminal pre-configure multiple frequency ranges and beams before handover is needed. When handover signaling is received, the terminal can immediately switch to the pre-configured appropriate frequency range and beam without requiring time-consuming adjustments, thus resolving the contradiction between handover accuracy and handover time.
2Reliability
If different handover designs are implemented for different scenarios, then handover reliability is improved, but system complexity increases
Solution Approach 1:
The patent implements universality by designing a unified handover framework where a single set of mechanisms (multiple frequency range configurations, beam management procedures) serves multiple handover scenarios including intra-frequency, inter-frequency, and inter-RAT handovers. This universal approach maintains handover reliability across different scenarios while avoiding the complexity of entirely separate design implementations for each scenario.
Solution Approach 2:
The patent applies dynamics by enabling the terminal to dynamically select and switch between different frequency ranges and beams based on the current handover scenario and network conditions. The system maintains a pool of pre-configured options and dynamically activates the appropriate one, providing scenario-specific optimization without requiring static, scenario-dedicated designs.
3Duration of action of stationary object
If beam switching is performed before cell handover determination, then communication continuity is improved, but handover control precision decreases
Solution Approach 1:
The patent resolves this contradiction by applying preliminary action through pre-configuration of multiple frequency ranges and beams before handover is needed. The terminal prepares candidate beams and frequency configurations in advance but only activates them after receiving handover signaling and determining the target cell, thus maintaining communication continuity without sacrificing control precision.

AI summary
The present disclosure provides an information transmission method and apparatus, and a storage medium. The method comprises: receiving beam effective time information sent by a network device; and on the basis of the time of sending a positive acknowledgement (ACK) message of a layer 1 switching indication message or a beam indication message to the network device, and the time indicated by the beam effective time information, performing uplink and downlink transmission.
