Reception apparatus

Abstract

A transmission-reception apparatus does not configure ARQ control information from only sequence number, but the transmission-reception apparatus configures the ARQ control information such that the ARQ control information is comprised of one sequence number containing first occurrence of a corresponding packet's error, and bit information representing existence of retransmission requirements about sequence numbers followed on the heels of such the one sequence number.

       16 . A reception apparatus that receives data packets, comprising: 
 a generator that generates ARQ control information including bits that represent a sequence number of a data packet having a retransmission request and bits that represent existence and absence of a retransmission request with respect to data packets of subsequent sequence number; and    a transmitter that transmits the ARQ control information.
