Abstract: This application provides a multi-link-based communication method and an apparatus, to resolve a problem of an improper switching operation in an MLO. This application is applied to a wireless local area network system that supports a next-generation Wi-Fi protocol of IEEE 802.11ax, for example, 802.11 series protocols such as 802.11be, Wi-Fi 7, or EHT, and a next generation protocol of 802.11be, Wi-Fi 8, or Wi-Fi AI, and may be applied to a UWB-based wireless personal local area network system and a sensing system. According to the method, a related condition of a group addressed frame other than a trigger frame, a multi-station block acknowledgment frame, and a no-data PPDU announcement frame is added to a condition set, so that a non-AP STA can determine, based on information about the group addressed frame when performing a switching operation, whether to switch to a listening operation mode.

Abstract: A STA in a STA MLD sends an information frame on a link corresponding to the station, and the information frame is used to indicate a STA in an awake state in the STA MLD. An AP MLD receives the information frame, and sends a downlink message frame on a one or more links corresponding to a part of or all of STAs in the awake state in the STA MLD.

Abstract: A communication method includes determining a ranging signal, sending an nth fragment of N fragments of the ranging signal in a first time unit, and sending an (n+1)th fragment in a second time unit. The first time unit is one of M time units included in an nth time period, and the second time unit is one of M time units included in an (n+1)th time period, where there is a preset interval between the nth time period and the (n+1)th time period, n is an integer greater than 0 and less than N, and both N and M are integers greater than 1.

Abstract: The present disclosure suggests to expand and improve the method of utilizing channel resources in the 802.11be standard by allowing the use of multiple and non-contiguous portions of a channel. Supporting multiple resource units (MRUs) and non-contiguous resource units (RUs) improves the channel utilization by making it more efficient due to enhancing the capability of leveraging the channel selectivity. To this end, a wireless network device for resource allocation is provided and configured to define a non-contiguous MRU in the bandwidth of the channel. The channel comprises a plurality of RUs, and the MRU is defined based on non-punctured RUs after puncturing one or more of the RUs of the channel, and/or is defined by aggregating two or more non-adjacent RUs of the channel.

Abstract: This application provides a communication method and a communication apparatus. The method includes: A sending device sends a first physical layer protocol data unit PPDU over a first link, where the first PPDU carries a trigger frame. The sending device sends a second PPDU over a second link, where the second PPDU carries a second trigger frame; and an absolute value of a time difference between an end time of sending the first PPDU and an end time of sending the second PPDU is less than or equal to a first duration, and the first duration is related to a state turnaround time in a short interframe space (SIFS) time.
