发明名称 WIRELESS COMMUNICATION SYSTEM
摘要 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.

主权项 1. A method for a wireless station of a wireless LAN to communicate wireless signals using a 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 method comprising: receiving, by the wireless station, a wireless control signal via the primary frequency band from an additional wireless station, wherein the wireless control signal comprises a request to send communication data to the additional wireless station from the wireless station and a request to allocate a time period for transmitting the communication data; transmitting, by the wireless station via the primary frequency band instead of the at least one additional frequency band, a wireless response signal in response to receiving the wireless control signal, wherein the wireless response signal indicates (i) an allocated time period and (ii) that the at least one additional frequency band is allocated to the wireless station for transmitting the communication data during the allocated time period, wherein the wireless station transmits signals via the wireless LAN using carrier sense multiple access with collision avoidance; and receiving, by the wireless station, a first wireless communication data signal having the communication data via the at least one additional frequency band, wherein the first wireless communication data signal received via the primary frequency band is time-synchronized with a second wireless communication data signal that is simultaneously transmitted using the primary frequency band.
