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 multi-user 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 cause:
- generating a first frame that comprises a plurality of data units, and wherein each of the plurality of data units includes traffic information;
- transmitting the first frame to an access point;
- and
- receiving a second frame comprising a plurality of per station information fields, each of the plurality of per station information fields comprising a predetermined value.
An access point for facilitating communication in a wireless network for a multi-user transmission, the access point comprising:
- one or more memories;
- and
- one or more processors coupled to the one or more memories, the one or more processors configured to cause:
- receiving a first frame from a station, wherein the first frame comprises a plurality of data units, and wherein each of the plurality of data units includes traffic information;
- generating a second frame based on the first frame, wherein the second frame comprises a plurality of per station information fields, each of the plurality of per station information fields comprising a predetermined value;
- and
- transmitting the second frame to the station.
A computer-implemented method of facilitating communication in a wireless network for a multi-user transmission, the computer-implemented method comprising:
- generating a first frame that comprises a plurality of data units, and wherein each of the plurality of data units includes traffic information;
- transmitting the first frame to an access point;
- and
- receiving a second frame comprising a plurality of per station information fields, each of the plurality of per station information fields comprising a predetermined value.
