Abstract

Methods and apparatus for multiple user uplink are provided. In one aspect, a method for wireless communication includes receiving, via a first device, a first wireless message granting permission for the first device to transmit a message during a transmission opportunity, the first wireless message being transmitted to the first device at least partially concurrently with a transmission of at least a portion of a second wireless message addressed to a second device, the first wireless message being received over a first spatial stream and the second wireless message being transmitted over a second spatial stream; and transmitting, via the first device, a third message to a third device during the transmission opportunity at least partially concurrently with a transmission of a fourth message by the second device to the third device.

Claims

1. A method of wireless communication, comprising:

receiving, by a first device from a third device, a first wireless message for permission for the first device to transmit a third wireless message to the third device during a transmission opportunity, wherein a second device is granted permission to transmit a fourth wireless message to the third device during the transmission opportunity;

receiving, by the first device, a trigger frame from the third device after receiving the first wireless message;

decoding, by the first device, the trigger frame to determine to initiate transmission of the third wireless message during the transmission opportunity at a particular time; and

transmitting, by the first device, the third wireless message to the third device over a first spatial stream during the transmission opportunity concurrently with transmission of the fourth wireless message by the second device to the third device over a second spatial stream, wherein;

transmission of the third wireless message is initiated at the particular time based on the trigger frame; and

the trigger frame indicates when a single block acknowledgement will be transmitted by the third device to the first device and the second device.

2. The method of claim 1, wherein the trigger frame comprises a field indicating the particular time.

3. The method of claim 1, wherein the trigger frame indicates the particular time for initiating transmission of the third wireless message is a predetermined period of time after transmission of the trigger frame.

4. The method of claim 3, wherein the predetermined period of time is a short interframe space (SIFS).

5. The method of claim 3, wherein the predetermined period of time is a point coordination function interframe space (PIFS).
