Patent number: 12382282Abstract: Embodiments are disclosed for group cast with retries (GCR) in a multi-link wireless communications system. In some embodiments, an access point (AP) multi-link device (MLD) can exchange information with a non-AP MLD to establish a GCR-multi-link operation (MLO) agreement corresponding to a group address, wherein the information includes, but is not limited to: a GCR primary link or a GCR primary link set of the AP MLD, an association identifier (AID) that corresponds to the group address. In some embodiments, the AP MLD can transmit a GCR frame subject to the GCR-MLO agreement, where the GCR frame includes a sequence number assigned from sequence number space (SNS)_GCR_MLO defined at a MLD level, and generate a Group Temporal Key (GTK)_GCR_ML at the MLD level, where the GTK_GCR_ML enables encryption and decryption of the GCR frame.Type: GrantFiled: April 15, 2022Date of Patent: August 5, 2025Assignee: APPLE INC.Inventors: Qi Wang, Jarkko L.

Patent number: 12225506Abstract: Methods and apparatuses are disclosed for high-bandwidth stations in a WiFi environment. In embodiments, a bandwidth of communications supported by the access point is divided into multiple frequency segments. In an embodiment, bandwidths up to 320 MHz are supported, which can be subdivided into four frequency segments of 80 MHz each. Different stations park on different frequency segments, whereas the access point has its primary channel located on the first frequency segment. With this configuration, uplink and downlink channel access can be provided to the different stations using a primary channel hopping pattern, which is provided to the stations from the AP. This pattern provides time windows for each frequency segment, during which the stations in that segment are able to freely communicate. Several other aspects of the disclosure further support this configuration and other high-bandwidth configurations.Type: GrantFiled: September 30, 2021Date of Patent: February 11, 2025Assignee: APPLE INC.Inventors: Jinjing Jiang, Yong Liu, Tianyu Wu, Qi Wang, Su Khiong Yong, Jarkko L.
