Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G mobile communications, high-band spectrum resources face challenges in maintaining good coverage while supporting high data rates due to high path attenuation, and existing methods are inefficient in reducing resource indication overheads for beam-based communication.
Innovation Solution
A method involving a base station generating and sending first and second indication information to a terminal to determine its receiving or sending resources, which includes type and length information related to time units and quasi co-location parameters, reducing resource indication overheads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beam-based communication is used to improve coverage and reduce path attenuation in high-band communications, then coverage is improved, but resource indication overhead increases
Solution Approach 1:
The patent segments the resource indication into two parts: first indication information for resource configuration (type and length) and second indication information for resource relationships. This segmentation allows the terminal to efficiently determine resources without requiring complete explicit indication of all parameters, thereby reducing overhead while maintaining accurate beam-based resource allocation
Solution Approach 2:
The base station performs preliminary configuration by providing the terminal with first indication information (resource type and length) and second indication information (resource relationships) in advance. This preliminary action enables the terminal to autonomously determine its receiving and sending resources without requiring repeated detailed indications, reducing signaling overhead while ensuring reliable beam-based communication
2Measurement precision
If detailed resource indication is provided to ensure accurate beam allocation, then communication accuracy is improved, but signaling overhead increases
Solution Approach 1:
The patent changes the parameter representation by introducing type indication information and length indication information instead of directly indicating all resource parameters. This parameter transformation allows the terminal to derive complete resource information from compact representations, maintaining beam allocation accuracy while significantly reducing signaling overhead

AI summary
Embodiments of the present invention provide a communication method, an apparatus, and a system. The method includes: generating, by a base station, first indication information, where the first indication information is used to indicate configuration information of a first resource; generating, by the base station, second indication information, where the second indication information is used to indicate a relationship between a second resource and the first resource to a terminal; and sending, by the base station, the first indication information and the second indication information, so that the terminal determines its own receiving resource or sending resource. When the base station indicates the receiving resource or the sending resource of the terminal, according to the technical solutions provided in the embodiments of the present invention, resource indication overheads can be reduced.
