Antenna-Panel Switching Indication for Wireless Communication Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face high system overhead and low performance due to the inability of base stations to obtain antenna panel information of user equipment, leading to the need for frequent uplink beam sweeping.
Innovation Solution
A method for determining antenna-panel switching is introduced, where user equipment determines and reports antenna-panel switching indication information to the base station, allowing the base station to determine if antenna-panel switching has occurred and adjust its operations accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base station performs uplink beam sweeping before each uplink transmission or configures periodic uplink SRS for performing periodic uplink beam sweeping, then the uplink transmission performance is ensured, but the system overhead increases
Solution Approach 1:
The user equipment performs antenna-panel switching determination in advance based on downlink reference signals, and reports the switching indication information to the base station before uplink transmission. This preliminary action allows the base station to obtain antenna panel information without performing frequent uplink beam sweeping, thus ensuring uplink transmission performance while reducing system overhead
Solution Approach 2:
The user equipment reports antenna-panel switching indication information to the base station as feedback. This feedback mechanism enables the base station to obtain real-time antenna panel information of the user equipment, allowing the base station to adjust its transmission configuration accordingly without requiring continuous uplink beam sweeping, thereby reducing system overhead while maintaining transmission reliability
