  • Publication number: 20210409179
    Abstract: Embodiments of this application disclose a communication method and a communication apparatus applied to a wireless communication system, to provide a signaling design solution applicable to a scenario of multi-AP coordinated transmission. An embodiment of this application provides a communication method, including: a first access point (AP) generates notification information, where the notification information indicates a station (STA) that is to send a channel sounding physical layer protocol data unit (PPDU), the notification information includes identification information of the STA and identification information of a second AP, the identification information of the STA indicates the STA, and the identification information of the second AP indicates the second AP. The first AP sends the notification information to the second AP and to the STA.

  • Publication number: 20210360411
    Abstract: Embodiments of this application disclose a spatial reuse indication method and a wireless communications apparatus, thereby reducing a quantity of nodes that can participate in spatial reuse, reducing mutual interference between nodes in spatial reuse, and improving spatial reuse system performance. The method in some implementations includes a first access point generates a spatial reuse limitation indication and a spatial reuse group indication. The spatial reuse limitation indication can be used to indicate whether only a node in a spatial reuse group is allowed for spatial reuse and to indicate the spatial reuse group. The spatial reuse group includes one or more basic service sets. The first access point sends the spatial reuse limitation indication and the spatial reuse group indication.

  • Patent number: 11071168
    Abstract: In the present disclosure, an access point obtains a current network feature and generates a matching rule and an access rule, so that a station performs uplink access according to the matching rule and the access rule. This resolves a prior-art problem of reduced quality of service of a high-priority service because in an EDCA protocol, when there are relatively many low-priority service nodes, the high-priority service has difficulty in obtaining a resource through contention, or a conflict occurs between a low-priority packet and a high-priority packet. Effects of ensuring quality of service and user experience are achieved.

  • Publication number: 20210168795
    Abstract: This application provides a beacon frame transmission control method and a related apparatus. The method includes: generating, by a master access point AP, indication information used to indicate a transmission time period of a beacon frame of at least one secondary AP; and sending, by the master AP, the indication information to the at least one secondary AP, where the master AP and the at least one secondary AP belong to a same AP collaboration group, and transmission time periods of beacon frames of APs in the AP collaboration group are different. According to technical solutions provided in this application, transmission robustness of the beacon frame can be improved.
