Patent ID: 8780810

Claim:
A method of receiving data associated with extended access barring (EAB) in a wireless communication system, the method performed by a user equipment (UE) with delay tolerant access and comprising: determining whether a random access response is received from a base station (BS) during a random access response window, wherein the random access response window is set as a minimum time duration for the UE to check an existence of the random access response, wherein the minimum time duration is indicated by information included in system information, and wherein the random access response is received from the BS prior to a transmission of a random access preamble by the UE; if it is determined that the random access response is received during the random access response window, checking whether EAB application information included in the random access response indicates that the EAB is applied; if it is checked that the EAB application information indicates that the EAB is applied, receiving EAB information from the BS to perform an EAB check, wherein the EAB information is received via a system information block type 2 (SIB2) transmitted through a Broadcast Control Channel (BCCH), wherein the EAB information includes an EAB probability factor and a barring timer for each access class, and wherein the EAB checking is performed according to the EAB probability factor and the barring timer included in the EAB information; and if the UE is not barred by the EAB checking, transmitting the random access preamble to the BS.
