Wireless Carrier Resource Allocation via Frequency Division
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in resource allocation when multiple air interface technologies need to be used simultaneously, leading to low and inflexible resource utilization due to the time division manner of service transmission.
Innovation Solution
A method where a wireless access device determines the required air interface technologies and allocates separate resources for each on a carrier using a frequency division manner, allowing simultaneous support of multiple air interface technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If time division manner is used to transmit multiple services on a carrier, then service transmission is implemented, but resource utilization is low and inflexible
Solution Approach 1:
The patent transitions from time-division multiplexing to frequency-division multiplexing, adding a frequency dimension to resource allocation. This allows multiple air interface technologies to be transmitted simultaneously on the same carrier by assigning different frequency resources to different services, thereby improving both resource utilization efficiency and flexibility.
Solution Approach 2:
The patent segments the carrier frequency band into multiple frequency resources, where each frequency resource can be independently allocated to different air interface technologies. This segmentation enables simultaneous transmission of multiple services without time division constraints, resolving the contradiction between utilization efficiency and flexibility.
2Reliability
If dedicated subframes are allocated for a specific air interface technology, then service transmission is enabled, but the subframes cannot be used for other air interface technologies
Solution Approach 1:
The patent makes frequency resources universal by allowing the same carrier to support multiple air interface technologies simultaneously through frequency division. Each frequency resource can be dynamically allocated to different services based on demand, enabling one resource to serve multiple functions and improving both reliability and flexibility.
Solution Approach 2:
The patent introduces dynamic resource allocation in the frequency domain, where frequency resources can be flexibly assigned and reassigned based on real-time service requirements. This dynamic allocation mechanism maintains service transmission reliability while significantly improving resource allocation flexibility compared to static time-division dedicated subframes.

AI summary
Embodiments of the present invention relate to the field of communications, and provide a resource allocation method, an apparatus, and a wireless access system, so as to improve resource utilization and make resource utilization manners more flexible. The resource allocation method includes: determining, by a wireless access device, at least two first AI technologies that need to be used to transmit a service between UE and the wireless access device; allocating, by the wireless access device on a first carrier, at least two first resources that are in a one-to-one correspondence with the at least two first AI technologies, where the at least two first resources are used to transmit the service between the UE and the wireless access device; and sending, by the wireless access device, first resource allocation information to the UE, where the first resource allocation information is used to indicate a first resource corresponding to a first AI technology that needs to be used by UE that receives the first resource allocation information. The resource allocation method is applied to a scenario in which the wireless access device allocates a resource to the UE.
