- BACKGROUND ART hereinafter, as a conventional technique, for example, a communication system including at least one base station and a plurality (including one) of terminals present in a service area covered by the base station is implemented. General communication processing will be described.
- a base station has a function of selecting a terminal to which transmission is granted from among a plurality of terminals that transmit data transmission requests, a so-called scheduling function.
- a terminal basically transmits data according to its scheduling. I do.
- a terminal that has generated data to be transmitted requests data transmission to the base station.
- the information that the terminal notifies the base station as a transmission request may be, for example, the amount of data stored in the buffer, the transmit power that the terminal can output, and so on.
- the base station grants a transmission permission based on the information sent as the transmission request, the predicted channel quality when each terminal transmits data, and the allowable interference level at the time of reception at the own station. The terminal is selected, and an assignment signal is returned as a response to the transmission request.
- the base station notifies the terminal of the number of transmission bits of the dog that can be selected by the terminal, that is, the transmission rate (Rate) and the transmission permission time (Time). Then, the terminal selected by the assignment signal performs data transmission based on the received information. At this time, the terminal transmits data within the transmission permission time.
- Non-Patent Document 2 retransmission control at the physical layer (ARQ: Automatic Repeat request) is being studied (see Non-Patent Document 2). If the base station that received data from the terminal succeeds in receiving, An ACK signal is returned, and a NAK signal is returned if reception failed. Then, when the terminal receives the NAK signal, it transmits a transmission request again before retransmission, receives the allocation signal from the base station, and retransmits the same data to the base station again.
- ARQ Automatic Repeat request
- the present invention has been made in view of the above, and a communication method capable of improving a buffer use efficiency in a base station by improving delay of retransmission data transmission, and a terminal that executes the communication method. And provide base stations.
- a communication achievable in a communication system including at least one base station and a plurality (including one) of terminals existing in a service area covered by the base station S
- a retransmission step of autonomously transmitting retransmission data when a NAK signal indicating reception failure is returned from the base station and the transmission permission time assigned to the terminal to which the NAK signal is returned has expired, A retransmission step of autonomously transmitting retransmission data.
- retransmission data is autonomously transmitted even when the NAK signal is returned from the base station and the transmission permission time allocated to the terminal has expired. This makes it possible to greatly reduce the delay time that occurs when retransmitted data is transmitted, as compared with the related art that performs processing related to transmission of a transmission request and reception of an assignment signal during retransmission. Also, since the delay time can be reduced, the time for using a buffer for storing data that has failed in reception is also shortened, so that the buffer use efficiency is greatly improved.
