摘要:
Provided is a wireless environment information collection system including a plurality of wireless stations performing wireless communication using a CSMA/CA scheme over a first frequency channel, and a wireless environment information management unit collecting wireless environment information of managed wireless stations being connected through a wired network or a wireless network among the plurality of wireless stations, in which the wireless environment information management unit includes a unit which generates and outputs a channel measurement frame which determines the wireless stations performing stopping of communication over the first frequency channel for a fixed time, starting of measuring channel utilization of the first frequency channel, or both the stopping of communication and the starting of measuring among the managed wireless stations, and the managed wireless stations include a unit which performs, at a time designated by the channel measurement frame from the wireless environment information management unit, the stopping of the communication over the first frequency channel, the measuring of the channel utilization of the first frequency channel, or both the stopping of the communication and the measuring of the channel utilization, and which outputs the obtained wireless environment information to the wireless environment information management unit through the wired network or the wireless network.

In a system which performs wireless communication from an access point to stations using group identification information, the frequency of uses of group identification information that overlaps with that of another access point is reduced. An association between a station apparatus included in a group that is a target for simultaneous transmission and group identification information is stored, each station apparatus included in the group is notified of the group identification information, group identification information that is being used in the other access point apparatus is acquired, and if group identification information that is being used by the access point apparatus itself overlaps with the group identification information used by the other access point apparatus, the group identification information is changed so as to reduce the number of pieces of overlapping group identification information.

A wireless communication system includes a plurality of terminal apparatuses that perform communication using a first frequency band in which communication based on a random access scheme is performed and a second frequency band which is different from the first frequency band, a first base station apparatus that performs communication using the first frequency band, a second base station apparatus that performs communication using the second frequency band, and a cooperation control apparatus that selects a terminal apparatus that transmits user data via the first base station apparatus from among the plurality of terminal apparatuses based on information acquired by the first base station apparatus and the second base station apparatus. The cooperation control apparatus selects which of the first base station apparatus and the selected terminal apparatus acquires access right for transmission of the user data via the first base station apparatus, and notifies the selected terminal apparatus and the first base station apparatus of the selection result.
摘要:
In order to provide a wireless communication system capable of improving the throughput of wireless communication by effectively using frequency resources, in a wireless communication system in which a first wireless access point which communicates with one or more wireless stations within a first cell by orthogonal frequency-division multiple access and a second wireless access point which is capable of performing carrier sensing with the first wireless access point and communicates with one or more wireless stations within a second cell by the orthogonal frequency-division multiple access operate in cooperation with each other, the first wireless access point includes an access right acquiring means which acquires an access right when data to be transmitted is generated; and a transmitting means of permission for use which transmits permission for use of channels which are not scheduled to use within the first cell, to the second wireless access point in a period in which the access right is acquired, and the second wireless access point includes a communication means which communicates with the wireless station within the second cell via the channel in which the permission for use is acquired.
