Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G mobile communications, the dynamic transmission status configuration makes it difficult for base stations to determine whether interference measured by terminal devices is caused by other base stations or terminal devices, leading to suboptimal decision-making and system performance degradation.
Innovation Solution
The method involves terminal devices receiving configuration information to identify measurement resources and slot formats of non-serving cells, allowing them to report measurement quantity types related to these resources, enabling network devices to distinguish between interference assumptions and improve interference coordination and data transmission scheduling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dynamic transmission status configuration is implemented to increase flexibility, then adaptability is improved, but the ability to determine interference sources deteriorates
Solution Approach 1:
The patent introduces feedback mechanisms where terminal devices report measured interference information and slot format indications to the network device. This feedback loop enables the network to understand the actual transmission status and interference conditions in dynamic TDD systems, resolving the information loss problem caused by flexible configuration.
Solution Approach 2:
The patent uses slot format indication information as an intermediary to bridge the gap between dynamic transmission status and interference measurement interpretation. This intermediary carries critical information about uplink/downlink slot configurations, enabling the network to correctly interpret interference measurements without sacrificing flexibility.
2Ease of operation
If interference measurement is performed without slot format information, then measurement process simplicity is improved, but measurement precision deteriorates
Solution Approach 1:
The patent applies preliminary action by having the network device send slot format indication information to the terminal device before the terminal performs interference measurement. This allows the terminal to configure its measurement process with the correct slot format context in advance, maintaining measurement simplicity while improving accuracy through informed measurement configuration.

AI summary
This application provides a method for sending a measurement report, including: receiving, by a terminal device, first configuration information and second configuration information, where the first configuration information is used to indicate a measurement resource, and the second configuration information is used to indicate a slot format of a non-serving cell of the terminal device; and sending, by the terminal device, a measurement report to a network device, where a measurement quantity type of the measurement report is related to the slot format of the non-serving cell, and the measurement report is corresponding to the measurement resource. In this way, based on the slot format of the non-serving cell, the terminal device obtains interference assumption information on the measurement resource, further obtains the measurement quantity type of the measurement report corresponding to the measurement resource, and feeds back the measurement quantity type to the network device by reporting the measurement report. Therefore, the network device can effectively distinguish between interference assumptions, to more effectively perform decision behaviors such as interference coordination management and data transmission scheduling, thereby improving performance of an entire communications system.
