Methods, systems, and devices are provided for system information management in a wireless communications. A user equipment (UE) may identify a first value of a value tag in a first carrier, read a system information block (SIB) on the first carrier associated with the value tag, and identify a second value of the value tag in a second carrier. The UE may compare the first value with the second value and determine whether the read SIB on the first carrier may be utilized on the second carrier. Other techniques may include identifying a first value of a value tag for a first carrier linked with a SIB transmitted over the first carrier. The techniques may include determining a second value of the value tag for a second carrier indicating whether the SIB transmitted over the first carrier may be utilized on the second carrier.
