Wireless communication device and wireless communication device control method

A wireless communication device, comprising:

• a radio transceiver data configured to transmit and to receive data packets to and from a base station, and also to receive data packets transmitted to the base station by other devices;
• and
• a processor configured
• to compute a proportional hidden standby time during which no hidden node, which is a wireless communication device whose transmitted signals do not reach the wireless communication device, is transmitting a data packet to the base station, the proportional hidden standby time being computed on the basis of at least two of from among a proportional exposed communication time during which only one exposed node, which is a wireless communication device whose transmitted signals reach the wireless communication device, is transmitting a data packet to the base station, a proportional exposed collision time during which at least two exposed nodes are transmitting data packets to the base station, and a proportional exposed standby time during which no exposed node is transmitting a data packet to the base station,
• 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.
