Resource Allocation Method for MTC User Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing resource allocation methods for Machine Type Communication (MTC) User Equipment (UE) are inefficient due to high overhead and inflexibility, particularly in reducing uplink and downlink transmission bandwidth, which increases the cost of MTC user equipment.
Innovation Solution
A method and device for resource allocation that uses a first and second portion of total indication amount Q bits to efficiently indicate allocated resources, allowing for flexible allocation by determining values based on the smallest or largest resource index, reducing overhead and enabling flexible resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing resource allocation methods based on entire bandwidth are used, then resource allocation can be performed, but overhead is large and allocation flexibility is poor
Solution Approach 1:
The patent divides the system bandwidth into multiple subsystem bandwidths, each capable of independent resource allocation. This segmentation allows the base station to allocate resources within smaller, manageable bandwidth portions rather than treating the entire bandwidth as a single unit, thereby reducing control overhead and improving allocation flexibility for MTC devices with limited bandwidth capabilities
Solution Approach 2:
The patent enables different bandwidth configurations and resource allocation strategies for different subsystem bandwidths within the total system bandwidth. Each subsystem can be optimized locally for specific MTC requirements, allowing flexible adaptation to various device capabilities while reducing overall overhead through localized resource management
2Ease of manufacture
If uplink and downlink transmission bandwidth are decreased to reduce MTC device cost, then device cost is reduced, but resource allocation efficiency deteriorates
Solution Approach 1:
The patent implements dynamic resource allocation within subsystem bandwidths, where the base station can flexibly allocate resources based on real-time traffic demands and device capabilities. This dynamic approach ensures that even with reduced transmission bandwidth in MTC devices, resource allocation efficiency is maintained through adaptive scheduling and resource assignment within the available subsystem bandwidth
Solution Approach 2:
The subsystem bandwidth structure allows the same resource allocation mechanism to serve multiple purposes: supporting both reduced-bandwidth MTC devices and enabling efficient resource utilization across different bandwidth configurations. The base station can universally apply the resource allocation method across multiple subsystems, achieving both cost reduction for devices and maintained efficiency through multi-functional resource management

AI summary
Provided are a resource allocation method and device and an information feedback method and device. The resource allocation method includes: a resource allocation sending end sends information about resources allocated to a resource allocation receiving end to the resource allocation receiving end through a first portion and a second portion of total indication amount Q bits, the first portion contains first indication amount Q1 bits, and the second portion contains second indication amount Q2 bits, the number of resources allocated to the resource allocation receiving end is K, resource indexes corresponding to the K resources are Si, i ∈ [0, 1, 2...K-1], Si < Si+1, 1 ≤ K ≤ M, and M is the number of virtual continuous resources allowed to be allocated by the resource allocation receiving end. In the embodiments of the present invention, by performing resource allocation indication through the first portion and the second portion of the total indication amount Q bits, the overhead in the process of resource allocation is reduced and flexible resource allocation indication is realized.
