Provided are a display panel and a display device. The display panel includes a pixel driver circuit. The pixel driver circuit includes a light-emitting module, a drive transistor and at least one light-emitting control transistor. The drive transistor, the light-emitting control transistor and the light-emitting module are connected in series between a first power supply signal terminal and a second power supply signal terminal, and at least one of the drive transistor or the light-emitting control transistor is a first double-gate transistor. The first double-gate transistor includes a first gate, a second gate and a first source, and the second gate is electrically connected to the first source.

Display panel and display device

Embodiments of the present invention relate to the field of communications technologies and provide a method for transmitting system information, an apparatus, and a system, to reduce a delay in obtaining correct system information by a terminal device. One method includes: generating a system information block SIB, and sending the SIB in N time units of a SIB period, wherein a first time unit of the N time units includes a redundancy version number of the SIB that is set to 0, the SIB period comprises T time unit groups, and the T time unit groups comprise TSIB candidate sending time unit groups, wherein T&#x2264;T, each of the T time unit groups comprises A time units for a clear channel assessment (CCA), and each of the TSIB candidate sending time unit groups comprises r SIB candidate sending time units, and wherein N is a total quantity of SIB candidate sending time units comprised in one or more of the TSIB candidate sending time unit groups that the CCA is successful, and N&#x2264;T&#xd7;r.

Method for transmitting system information, apparatus, and system

This application provides a data transmission method and apparatus. The method includes: determining a first frequency hopping pattern and a second frequency hopping pattern, wherein the first frequency hopping pattern and the second frequency hopping pattern comprises a same index set of N indexes corresponding to N channels; sending, based on the first frequency hopping pattern, data in each time unit of a first time period by using one of the N channels; and sending, based on the second frequency hopping pattern, data in each time unit of a second time period by using one of the N channels, wherein the first period and the second period are consecutive time periods each comprising N time units, each time unit starts and ends at starting times of two adjacent channels.

Data transmission method and apparatus

A method includes determining, by a network side device, N fixed channels. The method further includes determining, by the network side device, a first fixed channel from the N fixed channels, sending, by the network side device, a discovery reference signal on the first fixed channel, and performing data transmission on a data channel through frequency hopping. The data channel includes a channel other than the N fixed channels. N is an integer greater than or equal to 2.
