A method of polling in a wireless communications system (70) includes prohibiting polling (73, 73a, 73b) within a first predetermined period and triggering a poll function (75, 75a, 75b) while polling is prohibited. After the first predetermined period (73, 73a, 73b) has expired the method determines that there are no protocol data units (PDUs) scheduled for transmission or re-transmission and that there is at least a transmitted PDU that is not acknowledged yet, and selects a PDU to schedule for re-transmission to fulfill the poll function (75, 75a, 75b). |
