Prohibition Buffer Status Reporting Timer D2D Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Device to Device (D2D) communication systems, there is a lack of efficient methods for configuring buffer status reporting timers, leading to frequent transmissions and inefficient network resource management.
Innovation Solution
A method and apparatus for configuring a new prohibition buffer status reporting timer in D2D communication systems, where a UE receives an indication from the network to prohibit BSR for a first group of logical channels, and only triggers BSR for a second group if specific conditions are met, allowing for controlled BSR triggering and network resource management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If BSR is triggered for all logical channels when buffer status changes, then buffer status information is kept up-to-date, but network resource waste increases due to frequent unnecessary transmissions
Solution Approach 1:
The patent segments logical channels into two distinct groups: first group logical channels subject to BSR prohibition and second group logical channels exempt from prohibition. This segmentation allows selective BSR triggering based on channel priority and network policy, preventing unnecessary BSR transmissions for low-priority channels while maintaining accurate buffer status reporting for high-priority channels, thus resolving the contradiction between reporting accuracy and resource consumption
Solution Approach 2:
The patent applies different BSR reporting policies to different logical channel groups based on their specific characteristics and priorities. The network configures separate prohibition configurations for each group, allowing local optimization where critical channels maintain frequent reporting while non-critical channels reduce reporting frequency, achieving both reliability and resource efficiency through differentiated quality of service
2Productivity
If BSR transmission is prohibited for certain logical channels, then network resource efficiency improves, but buffer status monitoring completeness deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the network receives BSR information from the UE and uses this feedback to make informed scheduling decisions. By selectively prohibiting BSR for specific logical channel groups while maintaining it for others, the network optimizes resource efficiency without losing critical buffer status information needed for effective resource allocation and scheduling
Solution Approach 2:
The patent applies partial action by prohibiting BSR for only the first group of logical channels while allowing it for the second group. This selective approach provides sufficient buffer status information for network scheduling decisions without the excessive action of completely blocking all BSR transmissions, achieving resource efficiency while maintaining information completeness

AI summary
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for configuring a new prohibition buffer status reporting timer in a D2D communication system, the method comprising: configuring with a first group of logical channel and a second group of logical channel; receiving, from a network, an indication indicating that Buffer Status Reporting (BSR) for the first group of logical channel is prohibited; and triggering a BSR for the second group of logical channel if a BSR trigger condition is met for the second group of logical channel not indicated by the indication.
