1. An apparatus used in a non-Access Point Station (non-AP STA), comprising processor circuitry configured to cause the non-AP STA to, when there is urgent data that must be transmitted in uplink without waiting for a scheduled slot:
generate a Protocol Data Unit (PDU) from the urgent data; and
transmit the PDU on a resource unit pre-assigned for urgent transmission, wherein the resource unit is multiplexed for uplink transmission from multiple non-AP STAs,
wherein in a Short Interframe Space (SIFS) between a data frame and an acknowledgement frame responsive to the data frame of ongoing Orthogonal Frequency Division Multiplexing (OFDM) two-way transmission between another non-AP STA and an AP STA, the PDU is transmitted on frequency domain resources for the ongoing OFDM two-way transmission between the another non-AP STA and the AP STA.
