Abstract: A station (STA)-side data acknowledgment apparatus includes a transceiver configured to send a data frame and send an acknowledgment request, and a processor configured to control the transceiver to send the acknowledgment request after a duration from an end of sending the data frame. The duration is greater than or equal to a transmission delay on a backhaul link between access points (APs). The acknowledgment request is an acknowledgment request for the data frame.

Abstract: A wireless transmitting device is configured to: obtain a compressed-mode PPDU that includes one or more SC fields, where each SC field corresponds to one MU-MIMO group of the one or more MU-MIMO groups and is indicative of a spatial stream configuration for user devices of that MU-MIMO group; and transmit the PPDU to the user devices of the one or more MU-MIMO groups over a predetermined BW. Further, a user device is configured to: receive a compressed-mode PPDU from a wireless transmitting device; and decode the PPDU to obtain a SC field corresponding to the MU-MIMO group that the user device belongs to.

Abstract: This application relates to the wireless communications field, is applied to, for example, a wireless local area network supporting the 802.11 be standard Methods and apparatuses for indicating an uplink parameter of a physical layer protocol data unit (PPDU) are described. In an example method, an access point (AP) generates and sends a trigger frame, where the trigger frame includes an uplink length field. The uplink length field is used to indicate lengths indicated by legacy signal (L-SIG) fields in a high efficient trigger based (HE TB) PPDU and an extremely high throughput (EHT) PPDU, or the uplink length field is used to indicate the length indicated by the L-SIG field in the EHT PPDU. A length value indicated by the uplink length field is a positive integer and is a multiple of 3 minus 2.

Abstract: A negotiation method for an operating mode, an initiator, a receiver, a chip system, a computer-readable storage medium, and a functional entity are disclosed. In operating mode (OM) negotiation, the initiator transmits an operating mode indication (OMI) to the responder. The OMI includes at least either of channel width indication information and space-time stream number indication information. A capability range of a channel width indicated by the channel width indication information is greater than 160 MHz. A capability range of the number of space-time streams indicated by the space-time stream number indication information is greater than 8. After receiving the OMI, the responder performs transmission with the initiator based on a negotiated OM.

Abstract: A resource unit combination indication method and a communication apparatus are provided. The resource unit combination indication method includes: A transmit end generates a physical layer protocol data unit (PPDU), and sends the PPDU. The PPDU includes a resource unit allocation subfield. The resource unit allocation subfield indicates a multi-resource unit (MRU) to which a 242-tone resource unit (RU) corresponding to the resource unit allocation subfield belongs, and further indicates a quantity of user fields corresponding to the resource unit allocation subfield. According to the application, one or more users may be indicated to use a plurality of contiguous or noncontiguous RUs for data transmission, to improve RU allocation flexibility of a system and spectrum utilization of the system.
