11. The apparatus of claim 7 , wherein the extended header comprises service connection IDentifier (ID) information polling ARQ feedback and ARQ feedback polling information, and
wherein the ARQ feedback polling information is represented as a type of the extended header.
12. 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;
allocating to the receive end a resource;
determining if ARQ feedback information is received from the receive end at an ARQ feedback transmission time point of the receive end using the allocated resource information;
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.
13. The method of claim 12 , further comprising, before the transmitting of the at least one ARQ block to the receive end, in a case of at least one of an initial access and a data service parameter determination with the receive end, determining the ARQ feedback transmission time point of the receive end.
