Dynamic Antenna Channel Allocation for Spectrum Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dynamic spectrum access methods result in waste of spectrum resources due to excessive antenna channel allocation beyond service requirements, leading to inefficient resource utilization and increased power consumption.
Innovation Solution
A user terminal requests and allocates available spectrum resources from a base station based on current service demand, calculating the minimum number of antenna channels needed to meet throughput requirements, thereby optimizing resource usage and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all or most antenna channels are enabled according to preset subcarrier mode, then network access capability is improved, but spectrum resource utilization deteriorates due to excessive allocation beyond service requirements
Solution Approach 1:
The patent implements dynamic antenna channel allocation where the terminal adapts the number of enabled antenna channels based on real-time service requirements and channel conditions. Instead of using a fixed preset subcarrier mode that enables all or most channels, the system dynamically adjusts channel allocation to match actual service demand, thereby improving spectrum resource utilization while maintaining necessary network access capability
Solution Approach 2:
The patent changes the parameter of antenna channel allocation from a fixed preset mode to a dynamic mode based on service requirements. By adjusting the number of enabled antenna channels as a variable parameter rather than a constant, the system optimizes spectrum resource usage while ensuring adequate network access performance
2Reliability
If all or most antenna channels are enabled according to preset subcarrier mode, then network access capability is improved, but device complexity increases due to managing excessive enabled channels
Solution Approach 1:
The patent reduces device complexity by implementing dynamic antenna channel allocation that adapts to service requirements. Instead of managing a large fixed number of enabled channels, the system dynamically adjusts the number of active channels, simplifying channel management overhead and resource allocation complexity while maintaining necessary network access capability
3Reliability
If all or most antenna channels are enabled according to preset subcarrier mode, then network access capability is improved, but power consumption increases due to activating unnecessary channels
Solution Approach 1:
The patent reduces power consumption by implementing dynamic antenna channel allocation where the number of enabled channels is adjusted according to actual service requirements. Instead of continuously operating all or most channels, the system activates only the necessary number of channels, thereby reducing power consumption while maintaining adequate network access capability
Solution Approach 2:
The patent changes the operational state of antenna channels from a static all-enabled mode to a dynamic mode where the number of active channels is adjusted as a variable parameter based on service demand. This parameter change optimizes the balance between network access capability and power consumption by activating only necessary channels

AI summary
The present invention discloses an access method and device. The method includes: sending, by a user terminal, a carrier extension request to a base station when a current service resource demand is greater than a specified threshold, where the carrier extension request is used to request the base station to allocate an available spectrum resource; receiving the available spectrum resource sent by the base station; obtaining through calculation, according to the current service resource demand and the available spectrum resource, a quantity of antenna channels that need to be enabled, and enabling an antenna channel corresponding to the quantity of antenna channels; and sending an access request to the base station, where the access request carries the antenna channel that is to be enabled by the user terminal. The user terminal requests the available spectrum resource from the base station according to the current service resource demand, so that the base station performs resource scheduling with effectively reduced complexity, and resource scheduling becomes fairer. The user terminal obtains through calculation, according to the current service resource demand and the available spectrum resource, the quantity of antenna channels that need to be enabled, and enables an appropriate antenna channel, thereby reducing power consumption of an antenna system of the user terminal, and saving energy.
