1. A wireless communication method comprising:

  • detecting a content associated with each of a plurality of system information blocks (SIBs) from the plurality of SIBs using a downlink channel in a wireless communication network;

    storing the content associated with each of the plurality of SIBs;

    detecting, from the downlink channel in the wireless communication network, bits corresponding to a first information associated with a coverage, the coverage corresponding to a Signal-to-Noise-plus-Interference-Ratio (SINR) below a cell edge SINR;

    detecting a second information indicating that the contents associated with each of the plurality of SIBs from the downlink channel are changed when a User Equipment (UE) is determined to have a coverage corresponding to a Signal-to-Noise-plus-Interference-Ratio (SINR) below a cell edge SINR based on the detected bits; and

    when the second information indicates that at least one of the contents stored in the SIBs is changed, invalidating the content in the SIBs whose change was indicated.
