Abstract: A receive terminal setting a non-delivery determination time for determining that a next data packet is not delivered after transmitting an acknowledgement (ACK) packet for a received data packet; when the next data packet is not delivered within the non-delivery determination time, the receive terminal repeatedly transmits a retransmission request (RACK) packet prompting the transmission of the next data packet; a transmit terminal specifies a non-delivered data packet using time difference information based on the time-of-day information of the received ACK packet and RACK packet and retransmits the specified data packet to the receive terminal; the time-of-day information here is a time stamp added by the receive terminal to each of the ACK packet and RACK packet when transmitted, or a time stamp added by the transmit terminal to each of the ACK packet and RACK packet when received.

Abstract: A communication apparatus is provided with a communication part, a response index calculation part, and a determination part. The communication part is configured to be capable of transmitting a packet to the terminal, via frequency carrier(s) of a base station to which the terminal is connected. The response index calculation part calculates a response index of the packet. The determination part determines the number of frequency carrier(s) used by the terminal in accordance with the result of the response index calculation by the response index calculation part. Determining a number of frequency carriers being used includes determining the number of LTE carrier waves being used by the terminal.
