Wireless communication system, central station, access equipment and communication method

Abstract

The invention provides a wireless communication system, which comprises a central station with the function of a base station controller and at least an access device controlled by the central station, wherein the central station and the access device are connected through adopting a wired mode, the access device is used to demodulate wired signals transmitted by the central station to radio frequency signals, transmits radio frequency signals to a destination wireless user, and modulates uplink radio frequency signals to wired signals to send to the central station, and the central station is used to do baseband processing, IF processing and radio frequency processing for data provided by a core network to get radio frequency signals, modulates the radio frequency signals to wired signals, transmits the wired signals to the access device which is corresponding to a destination wireless user of data, and demodulates the wired signals transmitted by the access device to radio frequency signals, does radio frequency processing, IF processing and baseband processing for the radio frequency signals, gets data transmitted by a wireless user, and supplies data to the core network. The invention further provides a central station, a base station and a communication method.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a wireless communication system. Background technique [0002] The structure of the current wireless communication system is as follows figure 1 As shown, a base station controller 11 controls a plurality of base stations (BS, Base Station) 12, and the base station controller 11 and the base stations 12 are connected by optical fibers or data lines, and all base stations 12 controlled by the base station controller 11 share base station control Each base station 12 includes a baseband processing part, an intermediate frequency processing part and a radio frequency processing part. [0003] As the data transmission rate of wireless communication continues to increase, and at the same time, more and more users need wireless communication services, and the geographical range is wider and wider. Therefore, in order to increase the coverage quality and coverage of wireless...
