1. A wireless communication system comprising:
a wireless terminal; a plurality of communication devices which perform wireless communication with said wireless terminal; and a host-side communication device capable of performing wireless communication with said plurality of communication devices, wherein each of said plurality of communication devices includes a control unit that, in a case where said communication device is under connection to said wireless terminal, acquires received information of an uplink signal from said wireless terminal and feedback information from said wireless terminal, and performs a determination as to whether or not coordinated multipoint transmission/reception processing by the wireless communication with said host-side communication device is necessary based on either of said acquired received information of said uplink signal and said feedback information, in a case of having determined that said coordinated multipoint transmission/reception processing is necessary, said control unit requests said coordinated multipoint transmission/reception processing to said host-side communication device, and in addition, transmits information to said host-side communication device, the information being necessary to decide other communication device cooperating with each of said plurality of communication devices for said coordinated multipoint transmission/reception processing, said host-side communication device includes a control unit that, in a case where said coordinated multipoint transmission/reception processing is requested, decides, based on said information, said other communication device cooperating with each of said plurality of communication devices for said coordinated multipoint transmission/reception processing, opens wireless lines for the communication device under connection to said wireless terminal and for said other communication device, and sends a same signal to said other communication device and the communication device under connection to said wireless terminal, thereby performs said coordinated multipoint transmission/reception processing, and said control unit of each of said plurality of communication devices controls a station including said control unit to function as a relay device in a case of transferring a signal with said host-side communication device through said wireless line. |
