Adaptive Transmitting Port Indication for 5G UE Performance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the context of 5G technology deployment, the limited coverage and fast signal fading of high-frequency bands pose challenges for communication performance, particularly when the number of antennae available for User Equipment (UE) is variable, leading to mismatched antenna usage and resource allocation conditions between the network and UE sides.
Innovation Solution
A method is provided to determine and indicate the number of transmitting ports used by UE based on performance degradation, allowing the network side to adjust resource allocation accordingly, ensuring optimal communication performance by distinguishing between a first number (e.g., 1) and a second number (e.g., 2) of transmitting ports for different frequency and bandwidth combinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of transmitting ports is increased to improve communication performance, then data transmission rate is improved, but device complexity and power consumption increase
Solution Approach 1:
The patent applies dynamics by making the number of transmitting ports configurable and adaptive rather than fixed. The network device can dynamically select between first and second numbers of transmitting ports based on channel conditions, UE capability, and deployment scenario, allowing the system to optimize between performance and complexity in different contexts
Solution Approach 2:
The patent changes the parameter of transmitting ports number from a static configuration to a variable parameter that can be adjusted based on different frequency bands, bandwidth parts, and channel conditions. This allows the system to adapt the number of ports (e.g., 1 or 2) to match actual communication needs, resolving the contradiction between maximizing performance and minimizing complexity
2Productivity
If high-frequency bands are used to increase spectrum utilization, then data transmission rate is improved, but coverage area is reduced and signal fading increases
Solution Approach 1:
The patent enables dynamic adaptation of transmitting ports based on the operating frequency band and coverage requirements. In high-frequency bands with limited coverage, the system can adjust the number of ports to optimize performance within the available coverage area, while in lower-frequency bands with wider coverage, different port configurations can be used to maximize spectral efficiency
Solution Approach 2:
The patent changes the operating parameters including number of transmitting ports, frequency band, and bandwidth part based on the specific deployment scenario and channel conditions. This allows the system to adapt to the trade-off between spectrum utilization and coverage by adjusting multiple parameters simultaneously
3Productivity
If antenna usage conditions are optimized to improve communication performance, then data transmission rate is improved, but resource allocation complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where the UE reports its capability and the network device receives this information to make informed decisions about resource allocation. The network device uses feedback about UE capability, channel conditions, and deployment scenario to automatically select appropriate transmitting port configurations, reducing the need for complex manual resource allocation while optimizing communication performance

AI summary
A method for indicating the number of transmitting ports of User Equipment (UE), a network device, UE and a computer storage medium are provided. The method includes that: if performance degradation exists for a present Band Combination (BC), whether the performance degradation exists for a present frequency and bandwidth combination or not is determined to obtain a determination result; and it is determined based on the determination result to indicate a network side that the UE uses a first number or second number of transmitting ports, the first number is smaller than the second number.
