System and method for transmitting/receiving hybrid automatic repeat request buffer capability information in broadband wireless access communication system

(57)    Abstract

Disclosed is a system and method for transmitting and receiving hybrid automatic repeat request HARQ) buffer capability information in a broadband 5 wireless access communication system. According to the system and method, a mobile station detects its own HARQ buffer capacity, and transmits a message including information about the detected HARQ buffer capability to

a base station. The  base   station  receives   the   message   and

determines    the   amount  of a transmission signal to be allocated to the

mobile station based on the HARQ 10 buffer capability, so that it is possible to

operate a HARQ scheme in accordance with the HARQ buffer capability of the
