A wireless communication device, a wireless communication system and a wireless communication method using a variable data transmission rate

摘要

A wireless communication device, a wireless communication system and a wireless communication method for preventing buffer over flow in the wireless communication device acting as a relay node, and for improving throughput within the whole system are disclosed. The wireless communication device (AP) includes an information acquisition unit (3) configured to acquire information on the amount of data relay processing in the wireless communication device and/or a neighbor wireless communication device; a priority calculation unit (4) configured to calculate transmission priority of the wireless communication device, based on the acquired information; and a priority determination unit (4) configured to determine a priority related parameter for data transmission from the wireless communication device, based on the transmission priority.
