1. A method, comprising:
receiving, at an access point (AP) device, respective indications of respective amounts of data corresponding to a common i) traffic category, ii) traffic stream, or iii) traffic identifier (TID), from multiple respective client devices among a plurality of client devices in a wireless local area network (WLAN) to which the AP device belongs, the respective indications of respective amounts of data corresponding to respective data to be transmitted to the AP device from the multiple respective client devices; determining, at the AP device, a maximum duration of simultaneous uplink transmissions to be transmitted from the multiple client devices, wherein determining the maximum duration includes using the received indications of amounts of data from the multiple client devices; transmitting, to the multiple client devices, a communication frame prompting the multiple client devices to simultaneously transmit independent data corresponding to the common i) traffic category, ii) traffic stream, or iii) TID, to the AP device, wherein the communication frame includes an indication of the maximum duration; and receiving, at the AP device, respective data streams simultaneously transmitted, in response to the communication frame, by the multiple client devices, wherein
the respective data streams are received at the AP device prior to the AP device transmitting any media access control data to the multiple client devices after the AP device transmits the communication frame,the respective data streams do not exceed the maximum duration,the respective data streams are received via i) respective spatial streams, or ii) respective sets of orthogonal frequency division multiplexing (OFDM) subchannels, andthe respective data streams correspond to independent data from the multiple clients, the independent data corresponding to the common i) traffic category, ii) traffic stream, or iii) TID. |
