MULTIUSER SIGNALING AND ACCESS REQUEST MECHANISMS

摘要

In an example of wireless communications, an access point (AP) may send a first trigger frame to multiple stations. In response, some or all of the stations may transmit their respective uplink frames to the AR The uplink frames may include status information of the stations such as buffered data size. The AP may send a second trigger frame, including resource allocation assignments to inform stations which sub-bands may be used to send their payloads to the AP. The AP may allocate sub-bands to stations based on the status information of the station. The AP may allocate a relatively narrow sub-band to one or more stations when the status information is not known to the AP. Status information may be provided in certain control fields of a data frame. Random access may be provided by assigning a sub-band to multiple stations. Other methods, apparatus, and computer-readable media are also disclosed.

主权项

1. A station for communicating in a wireless network, 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:
processing a first trigger frame;generating a first uplink frame in response to the first trigger frame and based on resource status of the station;providing the first uplink frame for transmission; andprocessing a second trigger frame that is based on the first uplink frame, the second trigger frame comprising a first allocation of resources for the station, the first allocation of resources comprising one or more sub-bands assigned to the station, the one or more sub-bands being a portion of an uplink channel bandwidth.
