Base Station Resource Allocation for MTC Channel Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies lack a feasible solution to prevent collisions between channel resources configured for different terminals in Machine Type Communication (MTC) systems, particularly in NB-IoT implementations, which can lead to communication inefficiencies.
Innovation Solution
A method and apparatus for resource configuration in a base station that postpones the time-domain position of resources for one channel if they overlap with another, using specific conditions such as overlapping areas in the time and frequency domains, to avoid simultaneous processing and collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If physical channel resources are configured for different terminals simultaneously, then resource utilization is improved, but resource collisions occur between terminals
Solution Approach 1:
The patent segments physical channel resources by associating them with different uplink bandwidth parts (BWPs) for different terminals. Each terminal is configured with specific BWP pairs (first BWP for uplink data, second BWP for uplink control), ensuring that resources for different terminals are divided into distinct segments that do not collide, while still achieving high overall resource utilization.
2Adaptability or versatility
If multiple types of terminals with different baseband processing capabilities are supported, then system adaptability is improved, but resource allocation complexity increases
Solution Approach 1:
The patent implements a universal resource allocation mechanism based on BWP configuration that works for all terminal types (single sub-carrier and multiple sub-carrier capabilities). The base station uniformly applies the method of configuring different BWP pairs for different terminals, making the system adaptable to various terminal capabilities without requiring complex terminal-specific allocation logic.

AI summary
The present document provides a method, an apparatus and a base station for resource configuration. The method includes: performing, when resources for a first type of channel allocated to a first terminal and resources for a second type of channel allocated to a second terminal satisfy a specified condition, a time-domain position of a first resource among the resources for the second type of channel is postponed. In one aspect, the problem of avoiding collision occurring between channel resources configured for different terminals in the related art can be solved, thereby avoiding collisions of channel resources and improving the communication efficiency.
