Provided is a radio communication device capable of reducing interference, caused by non-SR transmission, with a basic service set (BSS) performing spatial reuse (SR) transmission. An SR transmission resource control unit () of the radio communication device (SR initiator) () determines transmission resources for an SR signal to be transmitted by means of SR to a second BSS other than a first BSS to which the radio communication device () belongs on the basis of radio quality information transmitted from other radio communication devices (SR responders) in the first BSS. A radio transmission/reception unit () transmits the SR signal by using the determined transmission resources.

Radio communication device and radio communication method

This communication device is provided with: a reception circuit that receives information pertaining to at least one of a plurality of modes which pertain to the allocation of a common data signal to a plurality of sub-carrier groups; and a control circuit that, on the basis of the information pertaining to the at least one mode, controls the synthesis of the signal allocated to the plurality of sub-carrier groups.

Communication device and communication method

This wireless communication control device is a first wireless control device provided with: a control circuit that causes the waveform of a reference signal transmitted to a wireless communication device in coordination with a second wireless communication control device to differ, either in the frequency domain or the time domain, from the waveform of a reference signal transmitted to the wireless communication device by the second wireless communication control device; and a transmission circuit that transmits the reference signal.

Wireless communication control device and wireless communication control method to coordinate reference signal waveforms

This base station is provided with: a control circuit that generates information relating to a terminal group among a plurality of terminals, said terminal group being a target of transmission by non-orthogonal multiple access; and a transmission circuit that transmits the information relating to the terminal group during a period in which control information addressed to the plurality of terminals is transmitted.

Base station, terminal, and communication method

The present invention enables more efficient control of Multi-AP coordination. A base station, according to the present invention, comprises: a control circuit that generates shared information that is shared among a plurality of users and includes information pertaining to unassigned resources, and individual user information specific to each of the plurality of users; and a transmission circuit that transmits a control signal comprising the shared information and the individual user information.

Base station, transmission method, and reception method

A downlink wireless transmission device comprising: a control circuit that generates common information that is common to a plurality of users and unique user information that is unique to each of the plurality of users and corresponds to information pertaining to retransmission control, said common and unique information including information pertaining to retransmission control for each of the plurality of users; and a transmission circuit that transmits control signals including the common information and the unique user information.
