Uplink Header Compression for 5G Coverage and Resource Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, uplink transmission resources are often a bottleneck due to the limited ability of user equipment (UE) to utilize high frequency bands and wide bandwidths, leading to decreased coverage and inefficient use of transmission resources compared to downlink resources.
Innovation Solution
Implementing uplink data compression (UDC) methods, such as DEFLATE-based algorithms, to compress data at the UE and decompress it at the base station, ensuring efficient use of transmission resources and enhancing coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If uplink transmission uses high frequency bands and wide bandwidths, then data transmission rate is improved, but propagation loss increases and transmission distance decreases
Solution Approach 1:
The patent applies header compression techniques that create a compressed copy of the original packet header, replacing the full header with a condensed version containing only essential information. This reduces the overall data size transmitted over the uplink, thereby improving resource efficiency and extending effective transmission distance without sacrificing data rate.
2Productivity
If uplink data size is reduced through compression, then transmission resource efficiency is improved, but device complexity increases
Solution Approach 1:
The patent applies compression selectively only to the header portion of packets rather than the entire data payload. This localized approach reduces the computational burden on the UE while still achieving significant resource efficiency improvements, as headers typically constitute a substantial portion of overhead data.
Solution Approach 2:
The patent implements partial compression by focusing only on the header fields that benefit most from compression, rather than attempting to compress entire packets. This partial action approach achieves sufficient resource efficiency gains without requiring excessive processing complexity at the UE side.
3Loss of substance
If header compression is applied to all packets, then transmission overhead is reduced, but processing time and delay increase
Solution Approach 1:
The patent establishes compression context and parameters in advance through RRC signaling before actual data transmission begins. This preliminary configuration allows the UE to perform compression operations using pre-configured parameters, reducing real-time processing delay while maintaining effective overhead reduction.
4Length of stationary object
If uplink transmission power is increased to improve coverage, then transmission distance is improved, but device power consumption increases
Solution Approach 1:
The patent changes the parameter of data size through header compression, effectively reducing the amount of data that needs to be transmitted. This parameter change allows for more efficient use of available transmission power, extending effective coverage distance without requiring additional power consumption from the UE.
