Abstract
A communication device includes a receiver , a transmitter that executes first transmission processing and second transmission processing , and a controller that controls the transmitter in accordance with a radio quality of wireless communication so that either the first transmission processing or the second transmission processing is executed.
Claims8
A communication device comprising:
- a receiver configured to receive a packet from another communication device;
- a transmitter configured to execute:
- first transmission processing, in which an ACK (acknowledgement) indicating reception of a first number of packets is transmitted to the other communication device every time the first number of packets are received from the other communication device;
- and
- second transmission processing, in which an ACK indicating reception of a second number of packet/packets, the second number being smaller than the first number, is transmitted to the other communication device every time the second number of packet/packets is/are received from the other communication device;
- and
- a controller configured to control the transmitter to execute the first transmission processing when a radio quality of wireless communication with the other communication device is unfavorable,
- wherein the controller is further configured to control the transmitter to execute the second transmission processing when the radio quality of the wireless communication with the other communication device is favorable.

A communication method comprising:
- receiving a packet from another communication device;
- and
- executing:
- first transmission processing, in which an ACK (acknowledgement) indicating reception of a first number of packets is transmitted to the other communication device every time the first number of packets are received from the other communication device;
- and
- second transmission processing, in which an ACK indicating reception of a second number of packet/packets, the second number being smaller than the first number, is transmitted to the other communication device every time the second number of packet/packets is/are received from the other communication device,
- wherein the other communication device is configured to execute the first transmission processing when wireless quality of wireless communication with the other communication device is unfavorable, and
- wherein the other communication device is further configured to execute the second transmission processing when the radio quality of the wireless communication with the other communication device is favorable.
5 more elements
A communication system comprising:
- a first communication device configured to transmit a packet to a second communication device;
- and
- the second communication device, which is configured to receive the packet from the first communication device and, is configured to execute:
- first transmission processing, in which an ACK (acknowledgement) indicating reception of a first number of packets is transmitted to the first communication device every time the first number of packets are received from the first communication device;
- and
- second transmission processing, in which an ACK indicating reception of a second number of packet/packets, the second number being smaller than the first number, is transmitted to the first communication device every time the second number of packet/packets is/are received from the first communication device,
- wherein the second communication device is configured to execute the first transmission processing when wireless quality of wireless communication with the first communication device is unfavorable, and
- wherein the second communication device is further configured to execute the second transmission processing when the wireless quality of the wireless communication with the first communication device is favorable.
