  • Patent number: 11974342
    Abstract: This application discloses a multi-link establishment method and a related device. A multi-link association response frame carries radio bitmap information, to indicate an AP allowed to be associated with a radio of a STA MLD or a link allowed to be established by using a radio of a STA MLD, so that the radio subsequently switches between different APs or links. The multi-link association response frame carries link establishment status information, to indicate a link establishment status of each link that the STA MLD requests to establish, so that multi-link establishment is more flexible. The multi-link association response frame carries reassociation information, to indicate whether each parameter in association configuration information is reserved, so that a problem that signaling overheads are relatively large due to a reassociation operation is avoided. It can be learned that, in the multi-link establishment method, the foregoing information is carried to improve multi-link establishment flexibility.

  • Publication number: 20240129099
    Abstract: Embodiments of this disclosure provide a communication method and device, a storage medium, and a program product. According to the communication method of this disclosure, a physical layer protocol data unit (PPDU) is transmitted or received based on a tone plan of a first bandwidth. The tone plan includes a physical resource unit (PRU), and the PRU includes discrete subcarriers. According to embodiments of this disclosure, an original nominal RU is processed to obtain a PRU including discrete subcarriers. Discretized subcarriers of the PRU may be evenly distributed on a larger bandwidth without changing subcarrier division of the original nominal RU. When it is ensured that a large PAPR is not generated in data transmission due to discrete subcarriers, a transmit end can perform communication at a high transmit power.

The management frame does not need to carry a plurality of same specific elements in the multiple BSSID set. The described techniques can be applied to, for example, a wireless local area network system supporting IEEE 802.11ax next-generation Wi-Fi protocols, for example, 802.11 series protocols such as the 802.11be or the EHT.
