Abstract: This disclosure relates to methods and devices for configuring guard subcarriers in transmission subbands to reduce interband interference in a wireless communication network. In one implementation, the method may include determining that a first subcarrier spacing for a first radio frequency transmission band is less than a second subcarrier spacing for a second radio frequency transmission band, and the first radio frequency transmission band is close to the second radio frequency transmission band in frequency spectrum. The method may further include configuring a subcarrier of the first radio frequency transmission band as a guard subcarrier carrying dummy data when the first radio frequency transmission band and the second radio frequency transmission band are simultaneously used to transmit data loads.

Abstract: A method for operating a touch screen device and a touch screen device are provided. The method includes that: a touch screen device receives a user command, and identifies the user command (100); when the touch screen device identifies the user command as a mode switching command, the touch screen device switches an operation mode (200); herein the operation mode includes a left hand operation mode, a right hand operation mode or a normal mode. Through a predefined or user-defined operation command, the operation mode switching of a touch screen device may be achieved by a single hand, so the key problem of single-handed operation of a touch screen device with a large screen is solved; and the single-handed operation can be really achieved, thereby improving the user experience of a touch screen device with a large screen.
