A communication apparatus that supports sidelink communication, the communication apparatus includes, a scheduler configured to select one resource pool from a plurality of resource pools based on a selection criterion set for an individual one of the plurality of resource pools and information regarding sidelink communication, and a transmission unit configured to transmit control information and data by using a resource included in the resource pool selected by the scheduler, wherein the information regarding sidelink communication is a QoS (Quality of Service) condition requested when the data is transmitted via sidelink communication.

Communication apparatus, base station apparatus, and communication system

A base station device that allocates wireless resources to a terminal device and performs wireless communication with the terminal device using the allocated wireless resources, the base station device includes, deciding controller that decides, out of a plurality of retransmission patterns, a retransmission pattern for performing retransmission of data to the terminal device, in accordance with a communication state of wireless communication, and a transmitter that performs initial-time transmission processing of transmitting a control signal for wireless resource allocation control, and a data signal for data transmission including data to be transmitted to the terminal device, including retransmission pattern information relating to the retransmission pattern that has been decided, and retransmission processing of retransmitting the data signal including data to be transmitted to the terminal device, in accordance with the retransmission pattern that has been decided.

Base station device, terminal device, wireless communication system, and wireless communication method

A wireless communication device includes: a reception controller that receives a signal transmitted to a plurality of wireless communication devices including the wireless communication device, and acquires data included in a reception signal; a detector that detects a retransmission request for requesting retransmission of the data, the retransmission request being transmitted by another wireless communication device by using a channel in accordance with a position of the other wireless communication device, and that identifies the position of the other wireless communication device based on a channel in which the retransmission request has been detected; a determination unit that determines whether or not to relay data to the other wireless communication device in accordance with a distance to the position identified by the detector; and a transmitter that transmits the data acquired by the reception controller to the other wireless communication device when the determination unit determines to relay data.

Wireless communication device, wireless communication system, and wireless communication method

A communication device including, a subgroup management unit allocates each of N resources in the frequency axis direction at a first position in the time axis direction to each communication device as a first resource, allocates each of second to Nth resources in the time axis direction at a first position in the frequency axis direction to each of the communication devices as the second resource, allocates each of the second to Nth resources in the frequency axis direction at a second position in the time axis direction to each of other communication devices as the first resource, and allocates each of the third to Nth resources in the time axis direction at the second position in the frequency axis direction to each of the other communication devices as the second resource, and repeat this operation to allocate the first and second resources to a plurality of communication devices.

Communication device and communication system for selecting resources to be used for data transmission

A communication device includes a processor that selects a first resource such that the first resource that is used to transmit data by the communication device does not overlap with a second resource that is used to transmit data by another communication device located in vicinity of the communication device and a transmitter that transmits the data by using the first resource selected by the processor.
