Abstract: The present disclosure relates to feedback methods and apparatuses. In one example method, a first communication apparatus may receive first information. The first information includes at least one of channel state information (CSI) measurement quantity indication information for channel variation calculation, a CSI type and a rule that are for the channel variation calculation, or a feedback suggestion parameter. The feedback suggestion parameter indicates a suggested feedback form. The first information is used to select a second communication apparatus. The first communication apparatus may determine, based on the first information, whether to trigger the second communication apparatus/apparatuses to send a feedback result. Correspondingly, the first communication apparatus receives the feedback result.

Abstract: This application relates to the field of wireless communication, and in particular, to individually addressed traffic indication methods and apparatuses applicable to multiple links, for example, in a wireless local area network supporting an 802.11be standard. In an example method, a first access point (AP) of a first access point multi-link device (AP MLD) generates and sends individually addressed traffic indication information. The individually addressed traffic indication information is used to indicate whether a non-AP MLD associated with the first AP MLD has a downlink individually addressed traffic and whether a non-AP MLD associated with a second AP MLD has a downlink individually addressed traffic. The second AP MLD is an AP MLD to which a non-transmitted AP belongs. The non-transmitted AP is in a multiple basic service set identifier (BSSID) set in which the first AP is located.

Abstract: This application relates to the field of wireless communication, in particular, to a beacon frame transmission method in an EMLSR mode, and is applied to a wireless local area network supporting the 802.11be standard. A TXOP holder sends a first frame before a first delay prior to a next TBTT, where the first frame indicates TXOP termination on a first link. The first delay is used by an EMLSR non-AP MLD to change a spatial stream on a second link to a state supporting beacon frame reception on the second link. The non-AP MLD changes, within the first delay after the TXOP termination on the first link, a spatial stream on the second link to supporting successful beacon frame reception on the second link, and receives a beacon frame by using a spatial stream currently supported on the second link at the next TBTT.

Abstract: Provided are a method for performing feedback based on channel state information (CSI), a device, and a medium. In an example method, a sensing response device obtains CSI data based on channel estimation, and generates power delay profile (PDP) data based on the CSI data. Then, the sensing response device feeds back a part of PDP data in the generated PDP data. Therefore, feedback overheads are reduced. In addition, sensing performance is ensured to some extent.

Abstract: Embodiments of this application provide channel bandwidth configuration methods, devices, and computer readable storage media. An example method includes generating and sending an extremely high throughput (EHT) operation element. The EHT operation element includes a channel bandwidth field, a first channel center frequency field, and a second channel center frequency field. The channel bandwidth field indicates channel bandwidth information of a basic service set (BSS). The first channel center frequency field and the second channel center frequency field indicate channel location information of the BSS. The bandwidth information indicates a channel bandwidth in a plurality of channel bandwidths supported by a terminal. This application can be applied, for example, to a Wi-Fi system that supports the 802.11 standard, such as, the 802.11be standard.

Abstract: A data scheduling method and apparatus. The method includes: allocating, by an access point (AP), at least one of a plurality of primary channels to each of a plurality of stations (STAs), where active access is forbidden on the plurality of primary channels; and synchronously scheduling, by the AP, a STA on a channel including at least one idle primary channel, where the synchronously scheduled STA is a STA allocated to the at least one idle primary channel, and the at least one idle primary channel is at least one of the plurality of primary channels. The AP sets the plurality of primary channels, so that the AP can flexibly schedule the station by using the idle primary channel. This avoids a problem caused by setting only one primary channel, thereby improving data transmission efficiency.

Abstract: Embodiments of this application disclose a communication method between multi-link devices and an apparatus, and relate to the field of communications technologies, to reduce power consumption of a station multi-link device. A specific solution is as follows: A multi-link device includes a plurality of STAs, one STA operates on one of a plurality of links, and the STA determines a primary link in the plurality of links. A STA operating on the primary link in the multi-link device may receive information sent by the AP indicating whether the STA operating on the primary link has a downlink traffic, and/or information indicating whether a STA operating on a link other than the primary link has a downlink traffic. Therefore, the STA operating on the primary link may determine a link on which the STA having a downlink traffic operates in the multi-link device.
