A base station according to an embodiment of the present disclosure includes a generation unit (35) that generates a beacon including switching information (41) indicating whether to cooperatively use a frequency channel and a transmission unit (32) that transmits the beacon.

An information processing system comprising a portable information device, a relay apparatus that connects the portable information device to a network, and a server. The server includes a library in which, for each relay apparatus, an area where the relay apparatus is present is registered in association with relay apparatus identification information. The portable information device obtains connection authentication from the relay apparatus installed in an area where the own device is present, and when the authentication is successful, the relay apparatus that provides the authentication transmits the relay apparatus identification information to the server.

Examples of the present disclosure provide a data processing method and apparatus, a communication device and a storage medium. Being applied to a first Access Point (AP), the data processing method includes: resource allocation information of one or more second Basic Service Sets (BSSs) that use a same frequency band as a first BSS for the first AP is acquired; and a resource is allocated to a station within the first BSS according to the resource allocation information.

The present technology relates to a communication device and a communication method that enable the occupancy condition of a transmission channel to be recognized with ease. There is provided a communication device including a controller configured to perform controlling of transmitting a data signal to another communication device via a transmission channel, in which the controller performs controlling of selecting a training pattern corresponding to an occupancy time of the transmission channel among a plurality of types of training patterns and transmitting a signal with the selected training pattern attached to the another communication device via the transmission channel. The present technology can be applied to, for example, a wireless LAN system.

A method and an apparatus for STR in a wireless LAN that supports multi-links are disclosed. An operating method of a first communication node comprises the steps of: transmitting a first frame to a second communication node through a first link from among multi-links; receiving, from the second communication node, a response frame for the first frame through the first link; checking a channel occupancy time in a second link from among the multi-links on the basis of first information included in the response frame; and performing a sensing operation in a preset section after the end of the channel occupancy time in the second link.

A negotiation method for an operating mode, an initiator, a receiver, a chip system, a computer-readable storage medium, and a functional entity are disclosed. In operating mode (OM) negotiation, the initiator transmits an operating mode indication (OMI) to the responder. The OMI includes at least either of channel width indication information and space-time stream number indication information. A capability range of a channel width indicated by the channel width indication information is greater than 160 MHz. A capability range of the number of space-time streams indicated by the space-time stream number indication information is greater than 8. After receiving the OMI, the responder performs transmission with the initiator based on a negotiated OM.

A multi-link aggregation transmission method and a related apparatus. The method includes: a receive end receives at least one of a data frame and a BAR frame over a plurality of links between the receive end and a transmit end, where the plurality of links includes a first link. The receive end receives a block acknowledgment request BAR frame over the first link, where the BAR frame carries SSN_1 corresponding to the first link. The receive end adjusts, based on SSNs corresponding to all the links, a value of a current starting sequence number WinStart of a scoreboard window. The receive end processes, based on the adjusted WinStart, a data frame received over the plurality of links. The receive end can adaptively adjust the WinStart.

A communication apparatus establishes, in a case where a second radio link is established with a partner apparatus in communication in addition to an already established first radio link, the second radio link using information obtained by authentication processing executed at the time of establishing the first radio link.

Embodiments of this application provide a Wi-Fi communication method and apparatus, and relate to the wireless communication field. A station may obtain detection information including a start time point at which an access point actually sends a beacon packet to the station for one time, obtain a low power consumption parameter based on the detection information and a first time interval, and receive the beacon packet from the access point based on the low power consumption parameter. The low power consumption parameter includes an actual wakeup periodicity of the station and an actual receive window length within which the station receives the beacon packet, or the low power consumption parameter includes an actual wakeup periodicity of the station, and the actual wakeup periodicity of the station is greater than a preconfigured wakeup periodicity of the station.

This application provides a receive chain enabled state switching method and a first multi-link device. The method includes: A first multi-link device receives, by using a first link, a first frame sent by a second multi-link device to the first multi-link device; and the first multi-link device makes one or more second links be in a multi-receive-chain enabled state, where the second link is a link that is between the first multi-link device and the second multi-link device and that is different from the first link. The method provided in this application helps the second multi-link device perform data transmission with the first multi-link device on the second link in a timely manner by using a plurality of spatial flows. This application may be applied to a plurality of Wi-Fi systems supporting an 802.11 standard, for example, the 802.11be standard.
