Abstract: A communications method and device, to reduce service interruption time and signaling overheads that are generated when an access point that provides a communication service for a station changes because the station moves or changes a direction. First frames sent by different access points in an access point set to a station include a same sending address. In this way, when the station moves or changes a direction, the access point that provides the communication service for the station changes from one access point in the access point set to another access point. Because first frames sent by access points in the access point set include a same sending address, the station may consider the access point set as one access point.

Abstract: Embodiments of the present invention provide an access method, including: sending, to an access point, a first frame that carries uplink transmission requirement information; and if a second frame that carries information about an uplink transmission resource is received from the access point within agreed time period, sending uplink multi-user transmission data to the access point, where the uplink multi-user transmission data is transmitted on the uplink transmission resource; or if the second frame is not received within an agreed time period, accessing, by a station, a channel in a contention access manner that is based on carrier sense CSMA/CA. According to the method provided in the embodiments of the present invention, a channel access manner can be managed, a congestion degree of a system can be decreased, and channel utilization can be increased.

Abstract: In an ISS process, the initiator sends a first SSW frame in different sector directions by sequentially using an antenna in m antennas, where m is not less than 1 and is less than or equal to N, and in an RSS process, the initiator receives a second SSW frame in a parallel (e.g., simultaneous) omnidirectional manner by using M antennas, where the second SSW frame is sent by a responder in different sector directions, each second SSW frame carries information used to indicate a first SSW frame with best quality in the ISS process, and the M antennas include at least the m antennas, and determines an optimal transmit beam in the ISS process based on the received second SSW frame.

Abstract: A channel sense method, a network side device, and a terminal includes determining, by a network side device, a first sense resource used by a terminal to perform channel sense, where the first sense resource is another resource other than a resource in a cell in which the terminal is located and that is used by each terminal to perform data transmission; and sending first sense indication information to the terminal, where the first sense indication information is used to indicate the first sense resource. When the terminal performs sense on the first sense resource, another terminal in a same cell does not receive or send data on the first sense resource. If the terminal senses an interference signal, it can be determined that the interference signal is not an interference signal generated when the other terminal in this cell performs data transmission.

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.
