Radio communicating system, radio communicating method, radio station, control station and program

Abstract

A radio station communicates control information for multipoint cooperating communication, in which a plurality of radio stations takes part in data transmission/reception of a terminal, with another radio station taking part in the multipoint cooperating communication and/or a control station that manages the radio station.

1 . A radio station comprising:
 a processor configured to communicate with a radio terminal by cooperating with another radio station; and   a transmitter configured to transmit, to the another radio station, first control information regarding communication with the radio terminal in a first cell managed by the radio station, wherein the first control information includes:
 information regarding a physical resource block (PRB) to be used for communication with the radio terminal in the first cell; and 
 information of an identifier (cell ID) of the first cell. 
   
     
     
         2 . The radio station according to  claim 1 , further comprising:
 a receiver configured to receive, from the another radio station, second control information including:
 information regarding a physical resource block (PRB) to be used for communication with the radio terminal in a second cell managed by the another radio station; and 
 information of an identifier (cell ID) of the second cell. 
   
     
     
         3 . A communication method for a radio station, the method comprising:
 communicating with a radio terminal by cooperating with another radio station; and   transmitting, to the another radio station, first control information regarding communication with the radio terminal in a first cell managed by the radio station, wherein the first control information includes:
 information regarding a physical resource block (PRB) to be used for communication with the radio terminal in the first cell; and 
 information of an identifier (cell ID) of the first cell. 
   
     
     
         4 . The communication method according to  claim 3 , the method further comprising:
 the radio station receiving, from the another radio station, second control information including:
 information regarding a physical resource block (PRB) to be used for communication with the radio terminal in a second cell managed by the another radio station; and 
 information of an identifier (cell ID) of the second cell. 
   
     
     
         5 . A radio communication system comprising a radio station, wherein the radio station comprises:
 a processor configured to communicate with a radio terminal by cooperating with another radio station; and   a transmitter configured to transmit, to the another radio station, first control information regarding communication with the radio terminal in a first cell managed by the radio station, wherein the first control information includes:   information regarding a physical resource block (PRB) to be used for communication with the radio terminal in the first cell; and   information of an identifier (cell ID) of the first cell.   
     
     
         6 . The radio communication system according to  claim 5 , wherein the radio station further comprises:
 a receiver configured to receive, from the another radio station, second control information including:
 information regarding a physical resource block (PRB) to be used for communication with the radio terminal in a second cell managed by the another radio station; and 
 information of an identifier (cell ID) of the second cell.
