Abstract: Embodiments of the invention provide an OFDMA contention method and an access point. The OFDMA contention method includes: receiving, by an access point, a contention request frame transmitted by a station over a subchannel, and judging whether a sum of a number of stations succeeding in a contention in a current channel contention period and a number of stations succeeding in a historic contention is minor than a preset threshold; if yes, triggering the station to enter a next channel contention period, and repeatedly executing the steps of the receiving and the judging, until a number of stations succeeding in contentions is greater than or equal to the preset threshold. The OFDMA contention method and the access point can increase the number of the stations succeeding in contentions, thereby improving the throughput of an OFDMA system.

Abstract: This application provides a communication method and apparatus to reduce impact of channel contention of a first STA on a scheduled STA in an OBSS by restricting channel access of the first STA in a BSS in which a first AP is located, so as to increase a success rate of obtaining a channel by the scheduled STA in the OBSS. In the method, the first AP generates a first frame, where the first frame includes r-TWT SP information and first indication information, the first indication information indicates that the r-TWT SP information is r-TWT SP information of an OBSS of a BSS in which the first AP is located, the r-TWT SP information of the OBSS indicates whether the first STA is to terminate a TXOP at a start time indicated by the r-TWT SP information of the OBSS.

Abstract: Embodiments of this application relates to a multi-link communication setup method and a related apparatus. The method includes: a non-AP MLD sends an association request frame on a first link, to request multi-link setup. An AP MLD returns an association response frame on the first link, to notify whether multi-link setup succeeds. The AP MLD sets a second status code field of a multi-link element of the association response frame to a newly defined value, to indicate that a cause why a link is not accepted is that the first link is not accepted. This application is applied to a WLAN system that supports a next generation Wi-Fi protocol of 802.11ax, for example, 802.11be, Wi-Fi 7, or EHT, and other 802.11 series protocols; and for another example, a next generation protocol of 802.11be: Wi-Fi 8.

Abstract: A resource allocation method includes sending, by a first device, resource allocation information to a second device. The resource allocation information indicates a first virtual resource unit (VRU). The first VRU includes a plurality of contiguous subcarriers in a frequency domain. The resource allocation method also includes mapping, by the first device, the first VRU to a first physical resource unit (PRU) based on a mapping relationship. The resource allocation method further includes transmitting data on the first PRU. A plurality of subcarriers included in the first PRU are noncontiguous in the frequency domain.

Abstract: A first station in a first multi-link device generates a frame, wherein the frame indicates a maximum quantity of shared spatial streams supported by the first multi-link device. The first station sends the frame. A throughput of a station in a multi-link device is improved by enabling a station to use more spatial streams.

Abstract: A method includes: A multi-link device performs first channel contention on a first link, where an initial value of a backoff counter in the first channel contention is determined based on a first value of a contention window. The multi-link device may perform second channel contention on the first link when a value of the backoff counter becomes 0 in the first channel contention and the multi-link device does not perform transmission on the first link, where an initial value of the backoff counter in the second channel contention is determined based on a second value of the contention window, and the second value is equal to the first value or a minimum value of the contention window.
