摘要： A method and a wireless communication device to overcome a hidden node problem in a BSS. The method includes detecting that transmitting one or more data frames causing one or more nodes of an unsynchronized wireless communication network to become hidden nodes. The wireless communication device that causes the hidden node problem requests a time allocation for transmitting one or more data frames to at least one node of the unsynchronized wireless communication network and to transmit the one or more data frames using an antenna beam forming technique at the allocated time frame.
