1. A station (STA) comprising:
a receiver configured to receive, from an access point (AP), one or more physical layer convergence procedure (PLCP) protocol data units (PPDUs) over at least one of an upper or lower frequency band, each of the one or more PPDUs comprising a trigger frame, wherein the trigger frame includes an allocation of random access (RA) resource units (RA-RUs) and at least one target received signal strength indicator (TRSSI), wherein each of the RA-RUs and the at least one TRSSI are associated with one of the upper or lower frequency bands;
a processor configured to select an allocated RA-RU associated with one of the upper or lower frequency bands based on a priority level associated with the STA, the received at least one TRSSI, and at least one expected received signal strength indicator (ERSSI) at the AP, wherein each of the at least one ERSSI is associated with one of the upper or lower frequency bands; and
a transmitter configured to transmit, to the AP, a message in the selected RA-RU.
