Abstract: An angle of arrival estimation method and device, where a first device: collects a first signal from a second device using a reference antenna and a first antenna group; determines first channel state information (CSI); collects a second signal from the second device using the reference antenna and a second antenna group; determines second CSI; determines a phase difference vector between the first signal and the second signal based on a vector corresponding to the reference antenna in the first CSI and a vector corresponding to the reference antenna in the second CSI; compensates for the second CSI using the phase difference vector; and estimates an angle of arrival of the second device based on the first CSI and compensated second CSI.

Abstract: A first access point (AP) in a wireless local area network (WLAN) is configured to communicate with one or more non-AP stations associated with the first AP and at least one second AP. The first AP includes a communication interface configured to receive, from the one or more non-AP stations, a first subset of uplink packets transmitted by the one or more non-AP stations to the first AP and receive, from the at least one second AP, a second subset of the uplink packets transmitted by the one or more non-AP stations to the first AP. Moreover, the first AP comprises a processing circuitry configured to determine the uplink packets based on the first subset and the second subset.

Abstract: A communication method includes that a sharing AP selects a first beam width used to schedule a sharing STA during coordinated transmission, and the sharing AP sends a coordinated transmission notification to a shared AP, where the coordinated transmission notification includes a coordinated transmission parameter, where the coordinated transmission parameter is obtained based on the sharing STA and the first beam width, where the coordinated transmission notification indicates the shared AP to select, based on the coordinated transmission parameter, a shared STA and a second beam width that are used for coordinated transmission, where the second beam width is one of adjustable beam widths of the shared AP, and where the first beam width is one of at least two adjustable beam widths of the sharing AP.

Abstract: A communication method and system in a WLAN, and an apparatus, are disclosed. An access point device sends a first frame to a non-access point device. The first frame includes one or more groups of access point parameters. At least one group of the access point parameters includes parameters of a plurality of access points belonging to one neighbor device. The neighbor device is an access point multi-link device. The non-access point device is associated with the access point device.

Abstract: A position relationship determining method and apparatus includes determining a position relationship between a first wireless local area network (WLAN) device and a second WLAN device based on exceeded-bandwidth wireless channel characteristic data, where the exceeded-bandwidth wireless channel characteristic data is a result obtained after combining wireless channel characteristic data corresponding to all WLAN channels in a channel set, the channel set includes at least two WLAN channels, all the WLAN channels in the channel set belong to a single WLAN frequency band, a total bandwidth occupied by all the WLAN channels in the channel set is greater than 160 megahertz and is greater than a maximum single channel bandwidth supported by the single WLAN frequency band.
