RADIO COMMUNICATION SYSTEM, RADIO BASE STATION, RADIO TERMINAL, AND RADIO COMMUNICATION METHOD

摘要

The objective of the disclosed technique is to arrange that, when a radio terminal communicates with different radio base stations between UL and DL, another radio base station, which is different from the connected radio base station, be able to receive data from the radio terminal. A radio communication system disclosed herein comprises radio base stations and radio terminals that perform radio communications with the respective radio base stations. Each of the radio base stations comprises: a reception unit that receives first information related to first uplink resources that are not used by the other radio terminals performing the radio communications with the other radio base stations; and a downlink radio transmission unit that transmits, on the basis of the first information, second information indicating a second uplink resource, which is selected from the first uplink resources for transmission to the other radio base stations, to the radio terminal.
