Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems fail to effectively measure and manage uplink signal channels across neighboring base stations for multi-cell coordination, leading to interference and inefficient resource allocation.
Innovation Solution
A method and apparatus for resource allocation in base stations and servers that utilize uplink signal channels, allowing for the detection and measurement of signals from neighbor cells by allocating resources through indexing and ensuring non-overlapping time-frequency resources, enabling multi-cell coordination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If each base station independently operates the uplink signal channel, then device complexity is reduced, but multi-cell coordination capability deteriorates
Solution Approach 1:
A server is introduced as an intermediary to coordinate resource allocation across multiple base stations. The server receives resource allocation requests from base stations, manages resource index information, and distributes allocated resources to multiple base stations, enabling centralized multi-cell coordination without increasing individual base station complexity
Solution Approach 2:
The resource allocation function is segmented between base stations and a centralized server. Base stations handle local resource allocation requests and receive allocated resources, while the server manages overall resource coordination and information exchange, dividing the complex coordination task into manageable parts
2Productivity
If uplink signal channel resources are shared across neighbor cells, then resource utilization efficiency is improved, but resource collision probability increases
Solution Approach 1:
The system performs preliminary resource allocation through indexing before actual signal transmission. The server pre-allocates resource indices to different base stations based on their requests and channel conditions, ensuring that resources are assigned in advance without collisions, allowing efficient sharing while maintaining reliability
Solution Approach 2:
The system implements feedback mechanisms where base stations report resource allocation requests and channel quality to the server, and the server responds with allocated resource indices. This closed-loop feedback ensures optimal resource utilization while preventing collisions through centralized coordination
3Adaptability or versatility
If resource allocation is centralized through a server, then multi-cell coordination is improved, but system complexity increases
Solution Approach 1:
The centralized server performs multiple functions including receiving resource allocation requests from base stations, managing resource index information, determining optimal resource allocations, and distributing allocated resources. This multi-functionality consolidates coordination tasks into a single entity, improving multi-cell coordination without proportionally increasing overall system complexity

AI summary
The present disclosure relates to a method and apparatus for resource allocation in a base station and a server for multi-cell coordination using an uplink signal channel. The resource allocation method for a base station (eNB) may include: receiving resource allocation information containing information on resources allocated to the eNB; receiving, when there is a need to change the allocated resources, changed resource allocation information containing information on changed resources; and distributing the changed resources to user equipments. The resource allocation method for a server may include: allocating resources to an eNB; sending resource allocation information containing information on the allocated resources; and sending, when there is a need to change the allocated resources, changed resource allocation information containing information on changed resources. According to the present disclosure, it is possible to realize multi-cell coordination using an uplink signal channel through resource allocation of the eNB and server.
