1. A method for wireless communication performed by a station (STA), the method comprising:
receiving, from an access point (AP), a resource request poll indicating one or more requirements for low latency traffic and a number of bits that may be included in an uplink (UL) resource request report;
transmitting, to the AP, upon a determination that a data stream meets the indicated one or more requirements for low latency traffic, an UL resource request report, wherein the UL resource request report includes information within the indicated number of bits, wherein the information indicates at least one of: an amount of data of the data stream that is to be transmitted, priority information associated with the data stream, or a bitmap associating the UL resource request report with a plurality of traffic priorities; and
receiving, from the AP, a trigger frame in response to the UL resource request report.
