Multi-Antenna Communication Control by Antenna Group Characteristics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In diverse terminal devices with multiple antennas spaced apart, treating all antennas as having the same characteristics leads to difficulties in achieving sufficient communication quality due to varying transmission path characteristics.
Innovation Solution
A terminal device and network node system that identifies and distinguishes between antennas with common and differing characteristics, enabling tailored communication control settings for each group.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all antennas in a terminal device are treated as having the same characteristics, then the device complexity is reduced and ease of operation is improved, but communication quality deteriorates when antennas are spaced apart with different transmission path characteristics
Solution Approach 1:
The patent segments the plurality of antennas into multiple antenna groups based on their spatial arrangement and transmission path characteristics. Each antenna group is treated independently with separate communication control parameters, allowing the system to account for differences in transmission path characteristics while maintaining manageable complexity through grouped management rather than individual antenna control.
Solution Approach 2:
The patent applies local quality by assigning different communication control parameters to different antenna groups based on their specific transmission path characteristics. Each antenna group receives tailored control settings (such as different timing advance values, power control parameters, or beamforming configurations) that match its local environmental conditions and spatial orientation, thereby optimizing communication quality for each group's specific context.
2Reliability
If communication control is customized for each antenna group based on transmission path characteristics, then communication quality is improved, but the complexity of identifying and managing antenna groups increases
Solution Approach 1:
The patent performs preliminary action by pre-identifying and categorizing antennas into groups based on their spatial arrangement and expected transmission path characteristics before actual communication operations begin. This preliminary classification allows the system to establish antenna groups in advance, reducing the complexity of real-time detection and measurement during communication operations.
Solution Approach 2:
The patent implements self-service by enabling the terminal device to autonomously identify its own antenna groups and their characteristics without requiring external assistance from the base station. The terminal device independently analyzes its antenna arrangement, determines transmission path characteristics for each group, and configures appropriate communication control parameters, thereby reducing the overall system complexity and detection burden.

AI summary
A terminal device that comprises a plurality of antennas notifies a network to which the terminal device belongs of information according to which it is possible to specify at least one of, among the plurality of antennas, a second antenna having a predetermined characteristic in common with a first antenna included in the plurality of antennas, and a third antenna not having the predetermined characteristic in common with the first antenna.
