RANDOM ACCESS PPDU FOR WLAN SYSTEMS

摘要

In wireless communications for multi-users, an access point may transmit a first trigger frame to one or more stations. The first trigger frame may be for scheduling a first uplink multi-user transmission and may indicate a plurality of resources for indicating existence of data to be sent to the access point. The station(s) may process the first trigger frame received from the access point. In response to the first trigger frame, the station(s) may generate and transmit a respective first uplink frame to the access point. In some cases, the first uplink frame(s) from the station(s) does not have a data field and does have a signal indicating existence of data to be sent from the station(s) to the access point. The signal may be sent using a resource(s) of the plurality of resources. Other methods, apparatus, and computer-readable media are also disclosed.

主权项

1. A station for facilitating communication in a wireless network for 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:
processing a first trigger frame received from an access point, wherein the first trigger frame schedules a first uplink multi-user transmission and indicates a plurality of resources for indicating existence of data to be sent to the access point; andtransmitting, during the first uplink multi-user transmission to the access point and in response to the first trigger frame, a first uplink frame that has no data field and that has a signal indicating existence of data to be sent from the station to the access point, wherein the transmitting comprises transmitting the signal on a first resource of the plurality of resources.
