Beam Switch Request Signaling for Wireless Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, existing technologies fail to efficiently switch between beams to optimize information transmission, as the current beam used may not be the best available for transmitting information, leading to suboptimal performance.
Innovation Solution
The system and method for beam switching involve a transmitter that sends a beam switch request and measurement results, based on trigger events, including a list of beams ordered by their performance, allowing for automatic selection of the best beam for transmission, with a processor managing the process and retransmissions if necessary.

Engineering Contradiction Analysis
1Reliability
If beam switching is implemented to optimize information transmission, then communication quality and reliability are improved, but system complexity increases due to the need for beam management and measurement procedures
Solution Approach 1:
The UE autonomously performs beam measurements and determines beam switch requests based on pre-configured trigger events, eliminating the need for continuous network-controlled beam management. The network only needs to provide initial configuration parameters, after which the UE self-manages beam selection and switching decisions
Solution Approach 2:
The network pre-configures trigger events and measurement parameters before beam switching is needed. This preliminary configuration includes setting threshold values, measurement frequencies, and beam identification parameters, so that when beam switching is required, the UE can immediately execute the switch based on pre-established criteria without complex real-time negotiations
2Productivity
If continuous beam measurement and switching is performed to maintain optimal transmission, then information transmission efficiency is improved, but energy consumption increases
Solution Approach 1:
Beam measurements and potential switches are triggered periodically or event-driven rather than continuously. The UE measures beams and considers switching only when pre-configured trigger events occur, such as when signal quality falls below a threshold or at predetermined time intervals, reducing unnecessary measurements and energy consumption
Solution Approach 2:
The system dynamically adjusts measurement parameters such as measurement frequency, threshold values, and beam list size based on current communication conditions. When channel conditions are stable, measurement frequency is reduced; when conditions deteriorate, measurements become more frequent, optimizing the balance between transmission efficiency and energy consumption
