1. A first station (STA) of a plurality of stations (STAs), the first STA comprising:
a transceiver; and
a processor; wherein, the transceiver and the processor are configured to:
receive, from an access point (AP) a trigger frame comprising a common information field and a plurality of per-user information fields corresponding to the plurality of STAs, wherein each of the plurality of per-user information fields comprise: a resource allocation field indicating a resource unit (RU) for use by the corresponding STA of the plurality of STAs for uplink (UL) multi-user (MU) transmission, and a user-specific power adjustment field indicating receive power expected at the AP for use by the corresponding STA of the plurality of STAs for determining transmission power of the UL MU transmission; and
transmit, to the AP, a data transmission as part of the UL MU transmission using the indicated RU for the first STA and using a transmission power determined based on the indicated receive power expected at the AP for the first STA and a calculated downlink pathloss.
