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: This application is applied to an ultra-wideband (UWB)-based wireless personal area network system, including 802.15 series protocols, for example, the 802.15.4a protocol, the 802.15.4z protocol, or the 802.15.4ab protocol; a wireless local area network system that can support 802.11 series protocols such as a next-generation Wi-Fi protocol of IEEE 802.11ax, for example, 802.11be, Wi-Fi 7, or EHT, and for another example, a next generation protocol of 802.11be, and Wi-Fi 8; a sensing system; or the like. This application provides a signaling transmission method, including receiving a UWB test signal, determining indication information of a number of fragment signals of a UWB measurement signal based on the UWB test signal, and sending the indication information. The number of fragment signals of the UWB measurement signal is determined based on the UWB test signal. This reduces a probability of incorrectly configuring the number of fragment signals.

Abstract: This application provides a positioning method and a related device. The method includes: A positioning device receives a positioning start message, where the positioning start message is used to trigger the positioning device to position a to-be-positioned device; the positioning device records a displacement parameter generated in a movement process of the positioning device, where the displacement parameter includes a displacement direction and a displacement distance; the positioning device receives, in the movement process, a radio signal sent by the to-be-positioned device; and the positioning device obtains a relative position relationship between the positioning device and the to-be-positioned device based on the recorded displacement parameter and the radio signal sent by the to-be-positioned device. According to this solution, a to-be-positioned device can be accurately positioned by moving a positioning device, which can effectively reduce costs and complexity of a positioning system without adding another hardware device.

Abstract: Example methods and apparatus for indicating downlink service data are described. One example method includes sending, by a first station (STA), a request frame to a wireless access point (AP). The request frame includes listen interval information, the listen interval information includes duration of a first listen interval, and the first STA is equipped with main radio and a wake-up receiver. The first STA receives a response frame sent by the AP, where the response frame carries an identity allocated by the AP to the first STA, and the identity of the first STA comprises an identity of the wake-up receiver of the first STA. The first STA controls the wake-up receiver to wake up within the first listen interval, and receives a wake-up beacon frame periodically sent by the AP.

Abstract: The invention 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: 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.
