Abstract: The present application provides a simultaneous emission pixel compensation circuit and a display panel. Through adopting a transistor with a double-gate structure as a driving transistor, and through a bottom gate to regulate a threshold voltage of the driving transistor, compensation of positive and negative drift of the threshold voltage of the driving transistor is realized. Through introducing simultaneous emission technology and adopting a global signal to perform corresponding control, a number of a scan signal to scan row by row is decreased to only one, such that a circuit structure is simple and a number of transistors required is less, thereby facilitating integration in a panel.

When quality of a link from a terminal device to a source gateway station through a satellite is poor, the source gateway station sends third indication information to a target gateway station, so that the target gateway station feeds back second channel quality to the source gateway station, that is, quality of a link from the terminal device to the target gateway station through the satellite. The source gateway station determines, based on the second channel quality and first channel quality that represents the quality of the link from the terminal device to the source gateway station through the satellite, whether to switch the terminal device to the target gateway station.
