Solution Overview
Problem
In 5G communication systems, base station devices with multiple antenna panels face challenges in accurately recognizing which antenna panels are being used for beamforming, leading to incorrect beam sweeping and reduced frequency usage efficiency.
Innovation Solution
The implementation of a terminal device that receives sounding reference signal (SRS) setting information with spatial correlation, allowing it to set and transmit SRS using spatial domain filters that correspond to the recognized antenna panels, ensuring precise beamforming and increased frequency usage efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If beamforming is performed using multiple antenna panels, then frequency usage efficiency and throughput are improved, but the system cannot correctly recognize which antenna panels are being used, leading to incorrect beam sweeping
Solution Approach 1:
The patent introduces spatial correlation information as an intermediary element that links antenna panels to beam directions. This spatial correlation acts as a mediator that enables the terminal device to correctly identify which antenna panel corresponds to which beam direction, resolving the recognition problem while maintaining the benefits of multi-panel beamforming for improved frequency efficiency and throughput
2Productivity
If multiple antenna panels are used for beamforming, then throughput is improved, but the terminal device cannot correctly identify the active antenna panels, resulting in beamforming errors
Solution Approach 1:
The patent implements a feedback mechanism where the terminal device receives spatial correlation information from the base station and uses this feedback to correctly identify active antenna panels. This feedback loop ensures reliable beamforming by continuously updating the terminal's knowledge of which antenna panels are active, preventing beamforming errors while maintaining high throughput

AI summary
A terminal device and a communication method are provided. The terminal device includes a receiver for receiving sounding reference signal (SRS) setting information and setting information for signals having a spatial correlation set to a SRS, and a transmitter for transmitting the SRS. The SRS setting information includes information indicating the spatial correlation to the SRS. The receiver, when receiving the signals having the spatial correlation set to the SRS, sets a first spatial domain reception filter and a second spatial domain reception filter. The transmitter, when transmitting the SRS, sets a first spatial domain transmission filter and a second spatial domain transmission filter. The first spatial domain reception filter and the first spatial domain transmission filter are set with beam correspondence. The second spatial domain reception filter and the second spatial domain transmission filter are set with beam correspondence.
