Abstract: A power control method and apparatus are provided. The method includes: determining, by a first station obtaining a transmission opportunity (TXOP), status indication information after determining working statuses of M second stations during the TXOP, where the status indication information is used to instruct a second station in the M second stations that needs to receive data during the TXOP to remain in a listening state, and instruct a second station in the M second stations that does not need to receive data during the TXOP to enter a sleep state; and sending, by the first station, the status indication information.

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 disclosure provides a display device for head mounting, in particular a Maxwellian display device, with an enlarged eye-box. The display device includes a light source emitting light beams for forming an image, an optical system for guiding the light beams to a beam forming element. The beam forming element is configured to converge each of multiple sets of the light beams into a different point of convergence, for example on an exit pupil of the display device. Each point of convergence is a convergent viewing point for a user. The eye-box is thus enlarged.

Abstract: The present invention provides a display system for displaying image data. The display system comprises a light source; a spatial light modulator including a plurality of controllable reflective elements; a light source controller, configured to control the light source 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, 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 are increased significantly so as to be suitable for the light filed applications.

Abstract: Embodiments of the present invention disclose a state switching method and apparatus. The state switching method includes: receiving, by a first network node, a preset frame sent by a second network node, where the preset frame includes indication information used to indicate an on/off state of a main transceiver and/or a wake up receiver of the first network node immediately, after a specified time point, or within a specified time period; and controlling, by the first network node based on the indication information, to switch an on/off state of the main transceiver and/or the wake up receiver of the first network node. According to the embodiments of the present invention, energy is saved by using a preset frame to indicate an on/off state of a main transceiver and/or a wake up receiver of a network node after a specified time point or within a specified time period.

Abstract: A method and an apparatus are provided. The method includes: generating, by an access point (AP), a first frame including P station information fields, each of which corresponds to one resource unit (RU) allocated to a first station (STA), wherein P is a positive integer greater than 1, each station information field further includes end indication information, which indicates 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. According to the application, 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: 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.
