Abstract: 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.

Abstract: The subject technology provides for block acknowledgment requests and block acknowledgment frames that can be used in conjunction with multicast transmissions that include multiple concurrent streams. Thus, the subject technology reduces the overhead associated with multicast transmissions that include multiple concurrent streams by aggregating the acknowledgments across multiple streams into a block acknowledgment, thereby increasing the effective throughput of such transmissions and overall network efficiency.

Abstract: The subject technology provides a receiving device with an indication of a last packet being transmitted in a group of packets. In this manner, the receiving device can enter a low power mode after determining that the last packet in the group of packets has been received (e.g., in addition to all prior packets in the group). For example, in the subject system a transmitting device may provide an indication of the sequence number of a last packet in the group, such as by inserting the indication into a header of one or more packets in the group of packets. In one or more implementations, each packet may include a sequence number, thus the sequence number of the last packet in the group may be the highest sequence number across the group.

Abstract: An access point transmits a trigger frame to a set of electronic devices in a wireless local area network (WLAN). In response to one or more requests to send data, the access point transmits the trigger frame, which includes information specifying an ordered list of electronic devices in the set of electronic devices that are allowed to transmit, and that groups the electronic devices in the ordered list of electronic devices into a first subset of the electronic devices and a second subset of the electronic devices. Subsequently, the access point sequentially receives one or more frames from the ordered list of electronic devices, where a first group of the frames received from at least some of the first subset of the electronic devices use single-user transmission and a second group of frames received from at least some of the second subset of the electronic devices use multi-user transmission.
