A method and an apparatus for performing extended access barring (EAB) in a wireless communication system are proposed. According to the proposed method, EAB application information is defined. In addition, when a base station receives an RA preamble within an RA response window, the base station sends an RA response a UE receives the RA response during the RA response window which is a minimum time interval to check the existence of the RA response. In the proposed method, the UE to which the EAB is set should wait the duration of the RA response window so as to receive the RA response before skipping initial EAB checking. If no RA response is received during the RA response window, the UE skips the EAB checking step in initial preamble transmission. [Reference numerals] (AA) Initiate new RA procedure; (BB,DD) RA response window; (CC) Receive RA preamble; (S610) RAR message; (S620) Check EAB application information; (S630) RRC connection request message; (S640) RRC connection reject message (with extended wait time or the indicator) |
