Abstract: An example wake-up packet sending method includes obtaining, by a sending apparatus, a wake-up packet (WUP), where the WUP includes a preamble sequence, and sending the WUP to wake up a main receiver of a receiving apparatus. The preamble sequence includes N consecutive first sequences S, where N is an integer greater than or equal to 2 (for example, [S S]), and the N consecutive first sequences S are used to indicate that a data rate used for the WUP is a first value. Or the preamble sequence includes a second sequence M, where the second sequence M is used to indicate that a data rate used for the WUP is a second value, and the second sequence M and a first sequence S are in a bit logical negation relationship.

Abstract: A method includes: generating, by an access point AP, a first frame, where the first frame includes P station information fields, each of the P station information fields corresponds to one resource unit RU allocated to a first station STA, P is a positive integer greater than 1, each station information field further includes end indication information, and the end indication information is used to indicate whether the station information field is the last station information field in the P station information fields. The AP may allocate P RUs to the first STA, and indicate the P RUs to the first STA through the P station information fields in the first frame. Therefore, a resource allocation manner of the AP can be more flexible, a frequency selective gain of an OFDMA system can be effectively improved, and a system capacity can be increased.

Abstract: The present invention provides a display system 100 for displaying image data. The display system 100 comprises a light source 101; a spatial light modulator 102 including a plurality of controllable reflective elements 1020; a light source controller 103, configured to control the light source 101 to emit, in each of a plurality of time intervals, light with a different illumination power level, wherein the time intervals have the same length; and a spatial light modulator controller 104, configured to activate, based on received image data, the plurality of controllable elements for at least one of the time intervals for directing the light from the light source for display the image data. Accordingly, the frame rate and bandwidth of the display system 100 are increased significantly so as to be suitable for the light filed applications.

Abstract: Example methods for indicating downlink service data and devices are described. One example method includes controlling, by a first station (STA) associated with a radio access point (AP), a wake-up receiver of the first STA to wake up within a preset first listen interval. The first STA receives a wake-up beacon frame sent by the AP, and controls main radio (MR) of the first STA not to wake up within a second listen interval to receive a beacon frame sent by the AP. According to the method provided in this application, the MR of the first STA does not need to wake up within the second listen interval to receive the beacon frame broadcast by the AP.

Abstract: This application relates to the wireless communications field and provides a frame transmission method, device, and system. The method includes: sending, by a second device, n wake-up frames to a first device, where the n wake-up frames each carry segmented content of wake-up signaling, so that a wake-up receiver of the first device wakes up a main transceiver of the first device based on the n wake-up frames, and after being woken up, the main transceiver sends, to the second device, a response frame used to indicate whether the n wake-up frames are correctly received. In this application, content of the wake-up signaling is segmented. In this case, lengths of the n wake-up frames are all relatively short, so that the wake-up receiver is easier to correctly receive each wake-up frame.
