Communications Node Dynamic Resource Allocation for Reliability and Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems between communications nodes lack flexibility, with Mode 1 offering high reliability but high delay and low flexibility, and Mode 2 providing low delay and high flexibility but risking resource conflicts and reduced reliability due to self-selected time-frequency resources.
Innovation Solution
A communications node determines third information that includes either allocated first information or self-selected second information, allowing flexible selection of resources for communication, thereby enhancing communication flexibility between nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Mode 1 is used where base station allocates time-frequency resources, then reliability is improved, but communication delay increases and flexibility deteriorates
Solution Approach 1:
The patent implements dynamic resource allocation mode selection, where the communications node can switch between base station scheduled mode (Mode 1) and autonomous selection mode (Mode 2) based on communication conditions. This dynamic approach allows the system to adapt to changing requirements, using base station scheduling when reliability is paramount and autonomous selection when low delay and high flexibility are needed, thus resolving the contradiction between reliability and delay.
2Ease of operation
If Mode 2 is used where communications node autonomously selects time-frequency resources, then communication delay is reduced and flexibility is improved, but resource conflicts occur and reliability deteriorates
Solution Approach 1:
The system dynamically adjusts the resource allocation mode based on current communication conditions and requirements. When flexibility and low delay are prioritized, the node operates in autonomous selection mode (Mode 2). When reliability becomes critical, the system transitions to base station scheduled mode (Mode 1). This dynamic switching mechanism resolves the contradiction by allowing the system to operate in the most appropriate mode for each specific communication scenario.
Solution Approach 2:
The patent changes the operational parameters of resource allocation by allowing the communications node to switch between two distinct allocation modes. By adjusting the control parameter (allocation mode) based on communication conditions, the system can optimize for either flexibility or reliability depending on the situation, thus resolving the contradiction between these two parameters.
3Reliability
If base station schedules time-frequency resources for communications nodes, then resource allocation reliability is improved, but system complexity and signaling overhead increase
Solution Approach 1:
The patent enables communications nodes to autonomously select time-frequency resources from a preset resource pool in Mode 2, eliminating the need for continuous base station scheduling and signaling. This self-service approach reduces system complexity and signaling overhead while maintaining reliable communication through autonomous resource selection, thus resolving the contradiction between reliability and system complexity.
4Adaptability or versatility
If communications node autonomously selects time-frequency resources, then communication flexibility is improved, but resource conflicts increase and reliability decreases
Solution Approach 1:
The system implements dynamic mode switching between base station scheduled allocation (Mode 1) and autonomous resource selection (Mode 2). When flexibility is the primary requirement and resource conflicts are manageable, the node operates in Mode 2. When reliability becomes critical or resource conflicts are detected, the system transitions to Mode 1 for more controlled allocation. This dynamic adaptation resolves the contradiction between flexibility and reliability.

AI summary
The present invention provides a data sending method, a base station, and a communications node. The sending method includes: sending, by a first communications node, first request information to a base station, where the first request information is used to request first information from the base station, and the first information is used to indicate authorization of a first resource; determining, by the first communications node, second information, where the second information is used to indicate authorization of a second resource, and the second resource is selected by the first communications node from a preset resource; determining, by the first communications node, third information, where the third information includes at least one of the first information and the second information; and sending, by the first communications node, data to a second communications node by using a resource indicated by the third information. The first information is allocated by the base station, the second information is determined by the communications node, and the communications node flexibly selects information for communication between communications nodes. In this way, both reliability and flexibility of the communication between the communications nodes are improved
