<p>PURPOSE: A random access apparatus and method are provided to effectively respond to influence on interference between cells by effectively determining the influence on the interference between the cells. CONSTITUTION: UE(User Equipment) is determined as victim UE or non-victim UE(S910). An eNB(evolved-NodeB) transmits a plurality of RAR(Random Access Response) window sizes to the UE(S920). The UE selects optimal RAR window size(S930). The UE a RAP(Random Access Procedure) using the selected RAR window size(S940). The RAS(Random Access Setup) of the victim terminal is transmitted as system information. [Reference numerals] (S910) Determining whether UE is victim UE; (S920) Transmitting ra_ResponseWindowSize&ra_ResponseWindowSize_forHetNet; (S930) Selecting a RAR window size; (S940) Random access procedure</p> |
