Spreading Code Configuration for Reliable Indoor 5G Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G communication systems, outdoor base stations face challenges in effectively covering indoor user equipment due to penetration loss and interference from overlapping time-frequency resources during repeated transmissions, which degrade service transmission reliability.
Innovation Solution
Implementing a configuration method that assigns unique spreading code sequences to each user equipment to process data, reducing interference by orthogonal coding and delaying transmissions to avoid resource overlap, thereby enhancing coverage and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If repeated transmissions are used to ensure coverage and improve service transmission reliability, then coverage and reliability are improved, but interference from overlapping time-frequency resources increases
Solution Approach 1:
The patent applies parameter changes by introducing spreading code sequences as a new parameter to differentiate repeated transmissions. Each transmission is assigned a unique spreading code, transforming the transmission signal characteristics to enable orthogonal separation of overlapping resources, thereby resolving the interference issue while maintaining reliability improvements
Solution Approach 2:
The spreading code sequence acts as an intermediary element that mediates between multiple repeated transmissions. By introducing this intermediate coding layer, the system can separate and identify individual transmissions within overlapping time-frequency resources, eliminating harmful interference while preserving the coverage enhancement benefits
2Object-generated harmful factors
If spreading code sequences are assigned to user equipment to reduce interference, then interference is reduced, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the interference management function into discrete spreading code sequences assigned to different user equipments. Each UE receives a specific code segment from the codebook, allowing independent processing and reducing overall system complexity through modular, standardized code assignment
