A method for polling transmission status in a transmitter of a wireless communications system includes forming a status protocol data unit including a poll sequence number field indicating a sequence number of a protocol data unit to be polled when a polling procedure is triggered to poll a receiver (402), setting a value of the poll sequence number field to be a sequence number of a next protocol data unit to be transmitted for the first time minus 1 (404), and transmitting the status protocol data unit to the receiver (406).
