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 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 prime frequency band, the wireless communication system comprising:
a wireless access system configured to employ a CSMA/CA and/or TDMA/TDD system as the wireless access system of the wireless communication system; wherein only the base station is configured to periodically broadcast a control signal at the prime frequency band to set the prime frequency band for all terminals wirelessly connected to the base station to indicate the prime frequency band for the all terminals, wherein the control signal comprises a control information configured to manage wireless data transmission by the all terminals; wherein the base station is further configured to allocate, in addition to the prime frequency band, one or more frequency bands different from the prime frequency band that can be used for the wireless data transmission by the all terminals, wherein the control signal at the prime frequency band indicates the location of the one or more frequency bands; wherein the control signal of the base station is set on the prime frequency band by the all terminals to make a time synchronization between the base station and the all terminals by the control signal, wherein the time synchronization is maintained by subsequent control signals at the prime frequency band being transmitted from the base station periodically and received by each of the all terminals; wherein the control signal is not transmitted at the one or more frequency bands for any of the all terminals, wherein the control signal comprises the control information to manage wireless data transmission by the all terminals being utilized instead of any control signal at the one or more frequency bands that is configured to manage the wireless data transmission by any of the all terminals at the one or more frequency bands, and wherein the all terminal are configured, based on the time synchronization by the control signal at the prime frequency band and the control information at the prime frequency band configured to manage the wireless data transmission by the all terminals, to time-synchronize and simultaneously carry out the wireless data transmission at the one or more frequency bands and the wireless data transmission at the prime frequency band.
