Abstract
A user equipment includes a receiving unit configured to receive a physical control channel and a physical shared channel from another user equipment; a control unit configured to calculate a distance that is an estimated distance between the another user equipment and the user equipment, based on information acquired via the physical control channel; and a transmitting unit configured to determine whether to transmit, via a channel used for transmitting and receiving a response relating to retransmission control, the response relating to the retransmission control of the physical shared channel transmitted from the another user equipment, based on the calculated distance.
Claims3
A terminal comprising:
- a controller that:
- determines a zone ID, based on latitude and longitude indicating a geographic location of the terminal;
- and
- sets, as a communication range requirement of a terminal, a value selected from predetermined numbers that correspond to communication ranges, respectively;
- and
- a transceiver that transmits, to another terminal using communication between terminals, control information including the zone ID and the selected value, wherein the control information is used to determine whether transmission of a hybrid automatic repeat request (HARQ) response is enabled,
- wherein the zone ID and the selected value are associated with information related to priority order.
A communication system comprising:
- a first terminal;
- and
- a second terminal, wherein
- the first terminal:
- determines a zone ID, based on latitude and longitude indicating a geographic location of the first terminal;
- sets, as a communication range requirement of a terminal, a value selected from predetermined numbers that correspond to communication ranges, respectively;
- and
- transmits, to the second terminal using communication between terminals, control information including the zone ID and the selected value, wherein the control information is used to determine whether transmission of a hybrid automatic repeat request (HARQ) response is enabled,
- wherein the zone ID and the selected value are associated with information related to priority order, and
- the second terminal receives, from the first terminal, the control information.
A communication method performed by a terminal, the communication method comprising:
- determining a zone ID, based on latitude and longitude indicating a geographic location of the terminal;
- setting, as a communication range requirement of a terminal, a value selected from predetermined numbers that correspond to communication ranges, respectively;
- and
- transmitting, to another terminal using communication between terminals, control information including the zone ID and the selected value, wherein the control information is used to determine whether transmission of a hybrid automatic repeat request (HARQ) response is enabled,
- wherein the zone ID and the selected value are associated with information related to priority order.
