A wireless communication system which includes: one or more wireless stations having a function of performing wireless communication based on a random access scheme in a primary frequency band and a function of performing the wireless communication in a secondary frequency band which is different from the primary frequency band; a first wireless access point performing the wireless communication with the wireless stations based on the random access scheme in the primary frequency band;and a second wireless access point performing the wireless communication with the wireless stations in the secondary frequency band, in which the first wireless access point and the second wireless access point are connected to each other through a network, the system comprising when a node transmitting user data is defined as a transmitting node and a node receiving the user data is defined as a receiving node for the first wireless access point and the wireless stations, a UD report transfer unit (15; 25; 36) transferring a user data, UD, report to the receiving node, the UD report includes information relating to transmission-waiting user data destined for the receiving node from the transmitting node, wherein according to the UD report being transferred, the receiving node includes a transmission opportunity control unit (15; 36) which sets a fixed transmission prohibition time in a channel in the primary frequency band for a wireless communication device in a vicinity, obtains a transmission opportunity, grants the transmission opportunity to the transmitting node, and causes the user data to be transmitted from the transmitting node, wherein: the UD report transfer unit (15; 25; 36) is configured to add, to the user data which is transmitted from the transmitting node to the receiving node, the UD report and to transfer the user data, the UD report includes one of a communication condition, starting and continuation conditions, and a termination command for communication based on the obtaining and the granting of the transmission opportunity in the receiving node; and the transmission opportunity control unit (15; 36) of the receiving node is configured to perform one of update and termination of the condition for the communication based on the obtaining and the granting of the transmission opportunity in the receiving node based on the UD report being added to the user data. one or more wireless stations having a function of performing wireless communication based on a random access scheme in a primary frequency band and a function of performing the wireless communication in a secondary frequency band which is different from the primary frequency band;
