1. An apparatus comprising:
a processor coupled to a memory, and
the memory having processor-executable instructions stored thereon, wherein the instructions are executed by the processor to cause the apparatus to perform operations including:
receiving one or more second requests for transmitting data from one or more of multiple stations,
wherein each of the one or more second requests comprises a first sequence identifying a first station among the multiple stations, and a second sequence identifying a second station among the multiple stations, and
wherein the first sequence is a first long training field (LTF) section which identifies the first station, the second sequence is a second LTF section which identifies the second station;
receiving a buffer message from each of the one or more multiple stations, wherein the buffer message indicates an amount of to-be-sent data at an associated station;
selecting buffer messages whose indication of to-be-sent data reaches a threshold, wherein reaching the threshold indicates a station associated with the buffer message needs to perform an uplink data transmission; and
determining one or more stations from the one or more multiple stations which have sent the second requests for uplink data transmission according to (i) a sequence in one of the one or more second requests, and (ii) the selected buffer messages.
