1. A radio communications system comprising:
a radio base station; and a plurality of radio communication terminal devices, the radio base station comprising:
a first memory; andat least one first processor coupled to the first memory which includes one or more following modules, when executed by the at least one first processor is configured to implementan area setting module that sets a part of an area of resources used for communication with the radio communication terminal devices as a search area,a plurality of schedulers that each select a resource included in the search area and belonging to a group allocated to each of the schedulers out of groups that are divided based on logical positions of resources, anda transmitting module that transmits a signal including control information by using the resource selected by each of the schedulers, the radio communication terminal devices each comprising:
a second memory; anda second processor coupled to the second memory, which when executing is configured to implementan acquiring module that receives the signal, search the search area in the received signal, and acquire control information addressed to the corresponding radio communication terminal device, anda communication module that performs communication with the radio base station based on the control information acquired by the acquiring module, wherein the resources used for communication include a plurality of types of resources having different sizes, the area setting module determines a size of transmission resources used for the communication with the radio communication terminal devices and sets a part of an area of the transmission resources as a search area, and each of the schedulers selects a transmission resource included in the search area and corresponding to a reference resource belonging to a group allocated to each of the schedulers out of groups created by dividing, based on the logical positions, division reference resources having a specific size out of the resources. |
