Patent ID: 8582683

Claim:
A wireless communication device for continuing wireless communication, using a transmission power and a modulation coding scheme (MCS) in accordance with a requirement from another wireless communication device in communication with the wireless communication device, the wireless communication device comprising: an obtaining unit for obtaining a received signal strength indicator (RSSI) and a signal to interference noise ratio (SINR) of a receive signal upon generation of transmission data to be sent to the another wireless communication device; a modulation and coding scheme determining unit for determining the MCS, based on a volume of the transmission data; a transmission power determining unit for determining the transmission power, based on the volume of the transmission data, the RSSI, the SINR, and the MCS determined; and a wireless communication unit for sending the transmission data, using the MCS determined and the transmission power determined, wherein upon generation of the transmission data, the transmission power determining unit determines the transmission power using the transmission power=a required SINR of the MCS determined by the modulation and coding scheme determining unit+an average interference power of an EXCH+a transmission power of an ANCH−a required SINR of the ANCH−an interference power of the ANCH.
