Title:
TRANSMISSION DEVICE, RECEIVING DEVICE, AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/195656
Kind Code:
A1
Abstract:
The number of data signals from terminal devices that are non-orthogonally multiplexed in a spatial domain increases when a plurality of terminal devices accommodated by a contention-based wireless communication technology share frequency resources. Consequently, transmission properties deteriorate due to residual interference following the removal of interference during receiving processing, when the number of data signals from the non-orthogonally multiplexed terminals is extremely high. Thus, a transmission device for transmitting a data signal to a receiving device has: a transmission processing unit for transmitting a data signal without receiving control information which allows transmission and is transmitted by the receiving device; a control information receiving unit for receiving in advance a transmission parameter pertaining to the data signal transmission; and a control information transmission unit for transmitting information about the expected traffic. Therein, the control information transmission unit transmits the amount of data and the frequency with which data is generated as the expected traffic information.
