Abstract
A wireless communication device, including a radio transceiver data configured to transmit and to receive data packets to and from a base station, and a processor configured to compute a proportional hidden standby time being computed on the basis of at least two of from among a proportional exposed communication time, a proportional exposed collision time, and a proportional exposed standby time, to compute a predicted PER from the proportional hidden standby time computed; to compute a threshold value for the number of retransmission attempts on the basis of the predicted PER computed, and to cause the radio transceiver to repeat transmission of a data packet to the base station until the number of transmissions exceeds the threshold value computed in the case of failed transmission of a data packet to the base station by the radio transceiver.
