Base Station Network Resource Allocation for Relay Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications networks, terminal devices often face challenges in accessing network resources due to contention mechanisms, leading to resource wastage and degraded user experience when a terminal device cannot obtain enough network resources to serve as a relay for another device.
Innovation Solution
A method where a base station allocates specific network resources, such as timeslots, frequencies, or code channels, to a first terminal device to enable a second terminal device to access a target device, thereby reducing resource contention and improving user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If terminal devices use capability-based contention for network resources, then devices with stronger capabilities can occupy more resources, but CF UEs cannot obtain enough network resources to serve AC UEs
Solution Approach 1:
The base station acts as an intermediary that manages and allocates network resources between CF UEs and AC UEs. Instead of direct capability-based contention, the base station receives service requests from AC UEs, identifies suitable CF UEs, and allocates dedicated network resources to the CF UE for relaying services to the AC UE, ensuring reliable service provision regardless of device capability differences
Solution Approach 2:
The patent changes the resource allocation parameter from capability-based contention to base station-controlled dedicated allocation. The base station adjusts resource allocation based on service requirements, CF UE availability, and network conditions, transforming the resource distribution mechanism from a static capability-based system to a dynamic service-oriented system that ensures CF UEs receive sufficient resources
2Productivity
If CF UEs contend for network resources using their capabilities, then stronger devices occupy more resources, but resource waste occurs when allocated resources are insufficient or inappropriate
Solution Approach 1:
The base station implements a feedback mechanism where AC UEs report service requirements, the base station identifies suitable CF UEs and allocates resources, then monitors the service quality and resource usage. Based on feedback about service success, resource utilization, and network conditions, the base station dynamically adjusts resource allocation to optimize efficiency and eliminate waste from inappropriate or insufficient allocations
Solution Approach 2:
The patent transforms the static capability-based resource allocation into a dynamic system where resource allocation is continuously adjusted based on real-time service requirements, CF UE availability, and network conditions. The base station can reassign resources, change allocation amounts, or select different CF UEs based on current conditions, optimizing resource utilization efficiency while preventing waste
3Ease of operation
If AC UEs discover CF UEs through channel detection, then AC UEs can find potential relays, but AC UEs cannot discover or access CF UEs when resources are insufficient
Solution Approach 1:
The base station performs preliminary actions by pre-identifying suitable CF UEs for AC UEs and pre-allocating network resources before the AC UE needs to access the network. This advance preparation ensures that when AC UEs search for CF UEs, the relay devices are already confirmed and equipped with necessary resources, eliminating access failures due to resource insufficiency
Solution Approach 2:
The base station serves as an intermediary that facilitates the discovery and access process. Instead of AC UEs independently detecting CF UEs without resource guarantees, the base station coordinates the entire process: identifying suitable CF UEs, allocating resources, and enabling reliable access, thereby ensuring both ease of operation and access reliability

AI summary
The present application discloses a method for allocating a network resource, a method for connecting to a target device in a network, a base station, and a terminal device. In the method for allocating a network resource, a base station receives request information sent by a first terminal device, where the request information is configured to request the base station to allocate a network resource; the base station sends, to the first terminal device, allocation information of the network resource allocated by the base station, where the allocation information is configured to indicate the network resource allocated by the base station; the first terminal device is a terminal served by a cell of the base station, and the second terminal device is a terminal that accesses the target device by using the first terminal device. Thus, a problem of network resource waste is reduced, and user experience is improved.
