Abstract:
1. An adaptive wireless parameter control method, for assigning a wireless parameter set including a maximum number of times for retransmission, a forward error correction scheme and a modulation scheme, for each packet to be transmitted including a different requested QoS information in accordance with the requested QoS information in mobile packet communication, comprising: determining whether or not the packet to be transmitted is a delayable packet; assigning, with a controller, a first maximum number of times for retransmission, a forward error correction scheme corresponding to the first maximum number of times for retransmission and a modulation scheme corresponding to the first maximum number of times for retransmission, for the packet to be transmitted, when the packet to be transmitted is determined to be a delayable packet; and assigning, with the controller, a second maximum number of times for retransmission which is smaller than the first maximum number of times for retransmission, a forward error correction scheme determined based on the second maximum number of times for retransmission and an observed QoS in an actual transmission and a modulation scheme determined based on the second maximum number of times for retransmission and the observed QoS in the actual transmission, when the packet to be transmitted is determined not to be a delayable packet.
