Abstract:
1. A method of using a wireless communication system having a base station and one or more terminals, the wireless communication system carrying out wireless data communication by use of a first frequency band, the method comprising: employing a centralized CSMA/CA and/or TDMA/TDD system as a wireless access system; periodically broadcasting from the base station a control signal at the first frequency band, the control signal configured to manage wireless data transmission of the one or more terminals; allocating, via the base station, in addition to the first frequency band, one or more frequency bands different from the first frequency band for data transmission of the one or more terminals, wherein the control signal at the first frequency band indicates the location of the one or more frequency bands which can be used, the control signal not being transmitted at the one or more frequency bands; simultaneously performing the wireless data transmission at the first frequency band and the wireless data transmission at the one or more frequency bands; receiving, at each of the one or more terminals, the control signal, which realizes a time synchronization of the wireless communication system, and thus, based on the time synchronization between the base station and the one or more terminals, the wireless data transmission at the one or more frequency bands is time-synchronized with the wireless data transmission at the first frequency band; wherein, the control signal at the first frequency band comprises control data configured to manage wireless data transmission of the one or more terminals at the first frequency band, the control signal at the first frequency band being utilized instead of a control signal at the one or more frequency bands that is configured to manage wireless data transmission of the one or more terminals at the one or more frequency bands, the control signal at the first frequency band being utilized in synchronization of frames between the wireless data transmission at the first frequency band and the wireless data transmission at the one or more frequency bands, permitting the simultaneous wireless data transmission both on the first frequency band and on the one or more frequency bands.
