Apparatus and method for arq feedback polling in wireless communication system

An apparatus for Automatic Repeat reQuest (ARQ) feedback polling in a transmit end of a wireless communication system, the apparatus comprising:

• a transmit apparatus for transmitting at least one ARQ block to a receive end;
• a receive apparatus for receiving a signal;
• and
• an ARQ controller for, after polling ARQ feedback to the receive end through the transmit apparatus, determining at least one of success and failure of transmission of the at least one ARQ block through the ARQ feedback information in a case where ARQ feedback information is received from the receive end through the receive apparatus within a lifetime of ARQ feedback, and for polling ARQ feedback again to the receive end in a case where the ARQ feedback information is not received within the lifetime of ARQ feedback,
• wherein the transmit apparatus polls ARQ feedback to the receive end using an extended header.

A method for Automatic Repeat reQuest (ARQ) feedback polling in a transmit end of a wireless communication system, the method comprising:

• transmitting at least one ARQ block to a receive end;
• polling ARQ feedback to the receive end using an extended header;
• determining if ARQ feedback information is received from the receive end at an ARQ feedback transmission time point of the receive end;
• if it is determined that the ARQ feedback information is received at the ARQ feedback transmission time point of the receive end, determining at least one of success and failure of transmission of the at least one ARQ block through the ARQ feedback information;
• and
• if it is determined that the ARQ feedback information is not received at the ARQ feedback transmission time point of the receive end, polling ARQ feedback again to the receive end.
