Abstract
In wireless communications for multi-users, a station may generate a first frame and transmit the first frame to an access point. The first frame may include media access control protocol data units (MPDUs). Each MPDU is associated with a traffic identifier (TID). In one aspect, a TID of one of the MPDUs is different from a TID of another one of the MPDUs. In response to receiving the first frame, the access point may generate a second frame based on the first frame. The second frame may include an indication that all of the MPDUs having TIDs are received. The access point may transmit the second frame to the station. Other methods, apparatus, and computer-readable media are also disclosed.
Claims20
A station for facilitating communication in a wireless network for a transmission, the station comprising:
- one or more memories;
- and
- one or more processors coupled to the one or more memories, the one or more processors configured to:
- generate a first frame that comprises a plurality of data units, wherein each of the plurality of data units is associated with traffic information;
- transmit the first frame to a wireless device in the wireless network;
- and
- receive a second frame comprising one or more per station information fields, each of the one or more per station information fields comprising a first subfield that is set to a first predetermined value, wherein the first subfield indicates whether the plurality of data units were received successfully and the first predetermined value to indicate successful reception of all of the plurality of data units carried in the first frame that has elicited the second frame.
A method for facilitating communication in a wireless network, the method comprising:
- generating, by a first wireless device in the wireless network, a first frame that comprises a plurality of data units, wherein each of the plurality of data units is associated with traffic information;
- transmitting, by the first wireless device, the first frame to a second wireless device in the wireless network;
- and
- receiving, by the first wireless device, a second frame comprising one or more per station information fields, each of the one or more per station information fields comprising a first subfield that is set to a first predetermined value, wherein the first subfield indicates whether the plurality of data units were received successfully and the first predetermined value to indicate successful reception of all of the plurality of data units carried in the first frame that has elicited the second frame.
A non-transitory machine-readable storage medium that includes instructions, which when executed by a processor of a first wireless device in a wireless network, cause the first wireless device to:
- generate a first frame that comprises a plurality of data units, wherein each of the plurality of data units is associated with traffic information;
- transmit the first frame to a second wireless device in the wireless network;
- and
- receive a second frame comprising one or more per station information fields, each of the one or more per station information fields comprising a first subfield that is set to a first predetermined value, wherein the first subfield indicates whether the plurality of data units were received successfully and the first predetermined value to indicate successful reception of all of the plurality of data units carried in the first frame that has elicited the second frame.
