Random access PPDU for WLAN systems
First Claim
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; and
transmitting, 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.

Abstract
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.

15. An access point for facilitating communication in a wireless network for 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; transmitting a first trigger frame to one or more stations, to schedule an uplink multi-user transmission with the one or more stations, wherein the first trigger frame indicates a plurality of resources for indicating existence of data to be sent to the access point; and receiving, during the uplink multi-user transmission, a first uplink frame from a first station of the one or more stations, wherein the first uplink frame has no data field and has a signal indicating existence of data to be sent from the first station to the access point, and wherein the receiving comprises receiving the signal on a first resource of the plurality of resources. - View Dependent Claims (16, 17, 18, 19)

20. A computer-implemented method of facilitating communication in a wireless network for multi-user transmission, the method comprising:
-
processing a first trigger frame received from an access point, wherein the first trigger frame is for scheduling a first uplink multi-user transmission and indicates a plurality of resources for indicating existence of data to be sent to the access point; and transmitting, 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 a station to the access point, wherein the signal is sent on a first resource of the plurality of resources.
