Split-Screen Terminal Control for Same-App Multi-Page Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing terminal devices lack the ability to actively display multiple operable pages of the same application simultaneously, limiting operation flexibility and user interaction.
Innovation Solution
Implement a method to control the terminal device's screen to display at least two split-screen windows, allowing a first page to be set to a preset state and dynamically moved to another window in response to user operations, enabling multi-window display of specific pages within an application.

If multiple terminals share the same frequency resource for uplink transmission, then frequency resource utilization is improved, but interference between terminals worsens
Solution Approach 1:
The system dynamically adjusts the uplink transmission parameters (cyclic shift values, orthogonal cover codes) based on real-time channel conditions and interference levels. The network device dynamically assigns different cyclic shift values to different terminals, allowing the system to adapt to changing interference conditions while maintaining frequency resource sharing, thus resolving the contradiction between resource utilization and interference management
Solution Approach 2:
The patent segments the frequency resource usage by introducing orthogonal resources (different cyclic shifts and orthogonal cover codes) for different terminals. Instead of all terminals using identical frequency resources simultaneously, the system divides the uplink transmission space into orthogonal segments, allowing multiple terminals to share frequency resources without causing mutual interference, thereby maintaining high resource utilization while eliminating interference
2Object-affected harmful factors
If the network device assigns different frequencies to different terminals to avoid interference, then interference between terminals is reduced, but frequency resource utilization deteriorates
Solution Approach 1:
The patent makes frequency resources universal by enabling the same frequency resource to serve multiple terminals simultaneously through orthogonal transmission techniques. Different terminals can use the same frequency resource with different cyclic shifts and orthogonal cover codes, making the frequency resource multi-functional and highly utilizable while maintaining interference-free operation
3Object-affected harmful factors
If the terminal uses a larger cyclic shift value to increase distance from other terminals in frequency domain, then interference avoidance is improved, but the available resource for data transmission decreases
Solution Approach 1:
The patent transitions from one-dimensional frequency domain separation to multi-dimensional orthogonal separation by introducing cyclic shift values and orthogonal cover codes as additional dimensions. Instead of requiring large frequency gaps, the system uses orthogonal resources in the code domain, allowing terminals to be separated in multiple dimensions simultaneously. This maintains interference avoidance while preserving maximum frequency resources for data transmission

AI summary
Embodiments of this application provide a terminal control method and apparatus, and a terminal device. The method includes: in response to a first operation performed on a terminal device, controlling a screen of the terminal device to display at least two split-screen windows, where the at least two split-screen windows include a first split-screen window and a second split-screen window, and the first split-screen window is used to display a first page of a first application; setting the first page to a preset state in response to a second operation performed on the first split-screen window; and displaying the first page in the second split-screen window and displaying a second page of the first application in the first split-screen window in response to a third operation performed on the first page, where the second page is a previous page of the first page. By using the first operation, the second operation, and the third operation, multi-window display for a specific page of the first application is actively implemented. This can effectively improve operation flexibility of the terminal device.
