Wireless communication system

Abstract

A wireless communication system that includes a base station and one or more terminals carries out wireless data communication by use of a first frequency band. The wireless communication system includes a wireless access system that employs a CSMA/CA and/or TDMA/TDD system as the wireless access system of the wireless communication system and a control signal at the first frequency band is periodically broadcasts from the base station, where the control signal includes a control information configured to manage wireless data transmission by the one or more terminals. In addition to the first frequency band, one or more frequency bands different from the first frequency band for the wireless data transmission by the one or more terminals can be allocate by the base station, where the control signal at the first frequency band indicate the location of the one or more frequency bands which can be used.

What is claimed is: 
     
         1 . A wireless station of a wireless LAN configured to communicate wireless signals using a plurality of frequency bands, wherein the plurality of frequency bands includes a primary frequency band and at least one additional frequency band, the wireless station comprising:
 a control processing circuit configured for:
 encoding, into a wireless control signal a request to send communication data to an additional wireless station and a request to allocate a time period for transmitting a communication data signal that includes the communication data, 
 decoding, from a wireless response signal, information that indicates an allocated time period and at least one allocated frequency band for transmission during the allocated time period that comprises the primary frequency band, and 
 identifying the allocated time period and the at least one allocated frequency band from the decoded wireless response signal; and 
   a wireless signal processing circuit configured for:
 receiving the wireless control signal from the control processing circuit, 
 transmitting the wireless control signal to the additional wireless station via the primary frequency band, 
 receiving the encoded wireless response signal from the additional wireless station, and 
 providing the wireless response signal to the control processing circuit for decoding. 
   
     
     
         2 . The wireless station of  claim 1 , wherein the wireless signal processing circuit is further configured for transmitting and receiving the wireless signals via the wireless LAN using carrier sense multiple access with collision avoidance. 
     
     
         3 . The wireless station of  claim 1 , wherein the wireless signal processing circuit is further configured for transmitting and receiving the wireless signals via the wireless LAN using time division multiple access.
