Systems and methodologies are described that facilitate collecting consistent system information when entering a cell during cell selection and/or cell re-selection in a wireless communication environment. SIB(s) can be received while lacking modification period information (e.g., modification period boundary, modification period duration, . . . ). Further, the SIB(s) can be stored in memory with corresponding SFN(s) at which the SIB(s) are respectively received. Thereafter, the modification period information can be identified (e.g., from a SIB2, . . . ). Moreover, an evaluation can be effectuated to determine whether to retain or discard the SIB(s) from memory as a function of the modification period information and the corresponding SFN(s). Further, whether to retain or discard the SIB(s) from memory can be based upon a value tag. According to another example, subsequent reception of the SIB(s) can be inhibited within a minimum modification period employed as a default prior to identifying the modification period information.
