Infrastructure Network Terminal Resource Allocation for Direct Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication methods in infrastructure networks are limited in supporting terminal-to-terminal communication and managing different types of terminals, especially in areas where direct communication between a base station and a terminal is impossible.
Innovation Solution
A communication method where terminals in an infrastructure network receive resource allocation information from the base station to determine communication times and frequency bands for downlink and uplink data with the base station and for terminal-to-terminal communication, allowing for independent communication using different frequency bands and time sections to prevent interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If infrastructure mode uses base station for centralized control, then network coverage area is improved, but terminal-to-terminal communication capability deteriorates
Solution Approach 1:
The patent enables terminals to perform multiple functions: they can communicate with the base station using infrastructure mode protocols and simultaneously communicate with other terminals using ad-hoc mode protocols. The terminal device is designed to support both communication modes, making it universal and adaptable to different communication scenarios without requiring separate dedicated infrastructure for each mode.
Solution Approach 2:
The base station acts as an intermediary that provides resource allocation information to terminals, enabling terminal-to-terminal communication. The base station transmits resource allocation information that includes time section and frequency band assignments for direct terminal-to-terminal links, allowing terminals to establish communication without the base station being the sole intermediary for all data flow.
2Device complexity
If terminals use same frequency band for all communication, then device complexity is reduced, but communication reliability deteriorates due to interference
Solution Approach 1:
The patent segments the communication resources by dividing the frequency band and time sections into separate allocations for different communication purposes. Specifically, it assigns a first frequency band and first time section for terminal-to-base station communication, and a second frequency band and second time section for terminal-to-terminal communication. This segmentation prevents interference between different communication types while maintaining manageable terminal complexity.
3Ease of operation
If base station manages all communication resources, then communication coordination is improved, but network adaptability to different terminal types deteriorates
Solution Approach 1:
The patent implements dynamic resource allocation where the base station provides resource allocation information that adapts to different terminal types and communication scenarios. The resource allocation includes flexible time section and frequency band assignments that can be adjusted based on traffic conditions, terminal capabilities, and communication requirements. This dynamic approach allows the network to accommodate various terminal types while maintaining centralized coordination benefits.

AI summary
A communication method between a plurality of terminals and a resource allocation method in an infrastructure network are disclosed. A terminal according to an embodiment communicates with at least one other terminal using a particular frequency band in a third time section distinguished from a first time section for reception of a downlink data and a second time section for transmission of an uplink data, thereby providing a technology of generating a small-scale network partly with respect to a particular region in a network with an extensive coverage of an infrastructure network.
