Abstract: Methods and apparatuses are provided in which an access point (AP) transmits a trigger frame to one or more user equipments (UEs). The trigger frame includes an indication of allocated resource units (RUs) for random access (RA). A UE allocates respective data to a sets of RUs for RA that are consecutive in a single frequency segment over a time domain of a physical protocol data unit (PPDU), based on the trigger frame. The UE transmits the PPDU to the AP.
