Title:
COMMUNICATION DEVICE, COMMUNICATION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2018/030021
Kind Code:
A1
Abstract:
[Problem] To further improve overall system transmission efficiency in a communication system in which a base station device and terminal devices communicate, even in conditions in which terminal devices having different reception capabilities are multiplexed. [Solution] This communication device is provided with: a communication unit for performing wireless communication; and a control unit which allocates resources for communication with each of a plurality of terminal devices which use channels having different bandwidths and/or centre frequencies. The control unit allocates, to a first region among the regions in which the resources are allocated, said first region overlapping the respective channels of the plurality of terminal devices, a first control channel which is transmitted commonly to the plurality of terminal devices. Furthermore, the control unit allocates, to a second region different to the first region, a second control channel which is transmitted separately to each of the plurality of terminal devices.
