Cross-Beam-Link Buffer Status Report for Mobility Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current BSR reporting methods in multi-linkage systems are inadequate for handling mobility management, particularly in scenarios involving multiple beam links, leading to communication latency and inefficient mobility management.
Innovation Solution
A method and apparatus for transmitting a cross-beam-link BSR, where a terminal receives an instruction message to report a BSR on one beam link, including a BSR corresponding to another beam link, to enhance mobility management by supporting cross-beam-link-BSR transmission, reducing communication latency, and improving mobility determination for macro base stations and primary serving nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the terminal sends BSR on each beam link separately, then the base station can accurately know the data status of each beam link, but the communication latency increases and mobility management becomes inefficient
Solution Approach 1:
The patent combines multiple BSR reports from different beam links into a single cross-beam-link BSR report. The terminal aggregates data buffer status information from multiple beam links and sends it through one beam link to the base station, reducing the number of separate reporting transmissions while maintaining comprehensive data status visibility for mobility management decisions
2Ease of operation
If the terminal establishes a new beam link to report BSR, then the reporting can be performed, but the communication latency increases due to link establishment time
Solution Approach 1:
The patent prepares alternative beam links in advance as backup reporting paths. When the primary beam link is unavailable or unsuitable for BSR reporting, the terminal can immediately use a pre-established alternative beam link without undergoing time-consuming link establishment procedures, thus reducing communication latency while maintaining reporting capability
3Adaptability or versatility
If multiple beam links are established for mobility management, then the system flexibility improves, but the device complexity increases
Solution Approach 1:
The patent makes a single beam link capable of carrying multiple functions by enabling it to transport BSR information from multiple different beam links through the cross-beam-link reporting mechanism. This universal beam link reduces the need for multiple dedicated reporting links while maintaining the ability to monitor and manage multiple beam connections for mobility purposes

AI summary
This application relates to the field of communications technologies, and discloses a method and an apparatus for transmitting a buffer status report, to help enhance mobility management on a terminal. The method may include: receiving, by a terminal, an instruction message, where the instruction message is used to instruct the terminal to report a BSR, the BSR includes at least one of a first BSR and a second BSR, the first BSR is a BSR corresponding to a first beam link, and the second BSR is a BSR corresponding to a second beam link; and then, reporting, by the terminal, the BSR on the first beam link according to the instruction message.
