Base Station Load Distribution via Idle Terminal Redistribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, over-loaded base stations experience service quality deterioration due to limited radio resources and backhaul capacity, necessitating efficient redistribution of idle terminals to low-loaded base stations to manage load distribution effectively.
Innovation Solution
The method involves determining an idle terminal percentage for redistribution at over-loaded base stations, broadcasting resource capacity status information, and prompting terminals to camp on low-loaded neighboring cells based on received information, ensuring real-time load balancing without unnecessary load information exchange.

Engineering Contradiction Analysis
1Productivity
If base stations serve a large number of terminals, then network coverage and service capacity are improved, but service quality deteriorates due to overloaded base stations
Solution Approach 1:
The patent implements dynamic load distribution by continuously monitoring base station load status and dynamically adjusting terminal distribution. The network side device determines idle terminal percentages and redistributes terminals from overloaded base stations to lightly loaded ones in real-time, making the system adaptable to changing traffic conditions and preventing service quality degradation.
Solution Approach 2:
The patent applies different load distribution strategies to different base stations based on their local load conditions. Each base station's idle terminals are redistributed according to its specific overload status, creating a localized optimization approach where heavily loaded areas receive more redistribution attention while lightly loaded areas maintain their current state.
2Stability of the object's composition
If idle terminals are redistributed from overloaded base stations, then load balance is improved, but network complexity increases due to additional control mechanisms
Solution Approach 1:
The patent introduces a network side device as an intermediary that centralizes the load distribution control logic. This intermediary calculates idle terminal percentages, determines redistribution targets, and manages the entire load balancing process, simplifying the complexity by consolidating control functions in a single entity rather than distributing complexity across multiple base stations.
Solution Approach 2:
The patent enables idle terminals to be automatically redistributed without manual intervention. The network side device autonomously monitors load conditions, identifies terminals eligible for redistribution, and executes the redistribution process, allowing the system to self-regulate its load balance status through automated control mechanisms.
3Measurement precision
If comprehensive load information is exchanged between base stations, then accurate load distribution is achieved, but signaling overhead and time consumption increase
Solution Approach 1:
The patent extracts only the essential load information needed for redistribution decisions - specifically the idle terminal percentage and basic load status - rather than exchanging comprehensive detailed load data between base stations. This selective information extraction reduces signaling overhead while maintaining sufficient accuracy for effective load distribution.
Solution Approach 2:
The network side device preliminarily determines the idle terminal percentage and identifies suitable redistribution targets before executing the actual terminal redistribution. This preliminary assessment phase allows the system to prepare redistribution plans in advance, reducing the time needed during actual load balancing operations and minimizing real-time information exchange requirements.

The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transfer rate beyond a 4th generation (4G) communication system, such as long term evolution (LTE). An operation method of a reception device in a wireless communication system comprises the steps of: receiving a signal transmitted through a plurality of antennas of a transmission device; determining an initial symbol vector on the basis of the signal; determining a first candidate symbol vector, on the basis of a plurality of solution vectors obtained by searching for the initial symbol vector; determining a second candidate symbol vector by changing at least one symbol value of the first candidate symbol vector; and determining a symbol vector transmitted from the transmission device, on the basis of at least a part of the second candidate symbol vector.
