摘要： This application relates to the communications field, and more specifically, to a beamforming training technology. In a beamforming training method, an initiator has N antennas. 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 (that is, 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. It can be learned that, compared with an existing manner in which sweeping (receiving) is performed by sequentially using a plurality of antennas, a multi-antenna parallel receiving manner used by the initiator in the RSS process of this application can save time and improve efficiency.

摘要： Embodiments of the present invention provide a method for establishing a communication connection between a STA and an access point. The method includes: receiving, by the AP, request frames sent by N STAs to the AP, where N is a natural number greater than or equal to 2; and after the AP receives the request frames sent by the N STAs, contending for a channel by the AP and sending one response frame to M STAs, where the response frame includes identifiers of the M STAs and M responses to the M STAs, each of the identifiers of the M STAs corresponds to one of the M responses, and the M identifiers and the M responses are used to instruct the M STAs to receive respective responses from the response frame sent by the AP, M is a natural number, and 2≤M≤N. By using the method, authentication response frames or association response frames for multiple STAs may be sent in one frame, thereby saving downlink resources.

摘要： Embodiments of the present invention provide a method for adjusting a clear channel assessment threshold and an access point. The access point includes: a receiving unit, configured to receive parameter information sent by another access point, where the parameter information sent by the another access point indicates a current channel occupation status of a basic service set in which the another access point is located; and an adjustment unit, configured to adjust a clear channel assessment CCA threshold of the access point according to the parameter information sent by the another access point. In the embodiments of the present invention, an access point adjusts a CCA threshold of the access point according to parameter information that is sent by a different access point and that indicates a current channel occupation status. Therefore, the CCA threshold of the access point can be adjusted dynamically, and communication efficiency is improved.

摘要： This application provides a data transmission method. When performing data transmission with a first station in a bandwidth power saving mode by using an operating channel of the first station, an access point performs data transmission with a second station by using an operating channel of the second station. Therefore, even if the operating channel of the first station includes a primary channel, the access point can still perform data transmission with the second station by using another channel. Further, for the access point, although the operating channel of the first station occupies only a part of available bandwidth resources of the access point, the access point can still perform data transmission with the second station by using a remaining channel. In this way, all bandwidth resources of the access point except for the operating channel of the first station can also be used for data transmission at the same time, improving resource utilization of the access point.

摘要： A signal field indication method and apparatus are provided, so that a SIG-A can transmit more information bits. The method includes: generating, by a transmit end, a PPDU, where the PPDU includes a SIG-A indication field, and the SIG-A indication field includes at least one of a field used to indicate a number of SIG-A information symbols and a field used to indicate a SIG-A information bandwidth; and sending, by the transmit end, the PPDU. According to the method provided in this application, the transmit end may indicate different numbers of SIG-A information symbols and/or different SIG-A information bandwidths.
