Abstract:
1. A wireless communication system comprising: a master station, which is a wireless access unit for managing access to a wireless network; and at least one slave station, which is one or more other wireless access units; wherein said master station and said at least one slave station are on the wireless network in which data is at least one of transmitted between said master station and said at least one slave station, and transmitted between said at least one slave station and another slave station by using at least one of: wherein said master station comprises: wherein said at least one slave station comprises means for providing said scheduler with a communication parameter for the data transmission which are needed by each of the communication types by transmitting communication parameters for the data transmission to said master station by using a request packet in order to make the request for setting the communication link for data transmission, the communication parameters including at least one of a part and an entire transmission amount, transmission speed, data period and priority; wherein said master station comprises means for giving the transmission band assignment packet scheduled by said scheduler to said at least one slave station by using a band assignment packet and recognizing the transmission band assignment; wherein said master station comprises means for transmitting, to said at least one slave station, the band assignment packet with a transmission time stamp value indicating a transmission time added thereto; wherein said at least one slave station comprises means for synchronizing a time counter of said at least one slave station with a time counter of said master station by using the transmission time stamp value transmitted from said master station; wherein a transmitting station and a receiving station between which the communication link is set by the transmission band assignment carry out bi-directional data transmission according to the transmission band assignment; and wherein said transmitting station is at least one of said master station and said at least one slave station which sends the data, and said receiving station is at least one of said master station and said at least one slave station which receives the data.
