Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G mobile communication systems, high-frequency signal energy decreases rapidly with distance, limiting transmission range, and network devices struggle to properly schedule antenna panels due to unknown on/off states, leading to low data transmission efficiency.
Innovation Solution
A method and apparatus that determine the status of antenna panels by sending feedback information indicating whether they are turned on or off, allowing network devices to properly schedule them for improved data transmission efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the terminal turns off some antenna panels to save electric energy, then energy consumption is reduced, but the network device cannot properly schedule the antenna panels resulting in low data transmission efficiency
Solution Approach 1:
The terminal feeds back the on/off status of antenna panels to the network device through uplink signals (PUCCH, PUSCH, or random access channel). This feedback mechanism enables the network device to obtain real-time status information of antenna panels, allowing proper scheduling decisions that balance energy saving and transmission efficiency.
2Device complexity
If the network device schedules antenna panels without knowing their on/off states, then scheduling complexity is reduced, but data transmission efficiency decreases
Solution Approach 1:
The terminal autonomously determines the on/off status of its antenna panels and actively reports this information to the network device. This self-service approach eliminates the need for the network device to complexly infer or track antenna panel status, reducing scheduling complexity while enabling efficient resource allocation based on actual hardware availability.

AI summary
This application provides a method and an apparatus for determining a status of an antenna panel. A terminal receives configuration information including at least one downlink signal resource set. When determining that a first antenna panel corresponding to a first downlink signal resource set is turned on, the terminal measures quality of a resource in the first downlink signal resource set by using the first antenna panel, and sends first feedback information. The first feedback information may indicate the quality of the resource in the first downlink signal resource set. When the first antenna panel is turned off, the terminal skips measuring the quality of the resource in the first downlink signal resource set, and sends second feedback information. The second feedback information is used to indicate that the first antenna panel is turned off. In this way, a network device in embodiments of this application can learn of a status of an antenna panel, and can properly schedule the antenna panel, thereby improving data transmission efficiency.
