description: The Master Information Block (MIB) is a crucial message in the context of 3GPP specifications, specifically within the LTE and 5G systems. It contains essential system information that is broadcast on the Broadcast Channel (BCCH), which is received by User Equipment (UE). The MIB includes vital parameters such as the system frame number, subcarrier spacing common, SSB subcarrier offset, DMRS type A position, PDCCH configuration for SIB1, cell barred status, intra-frequency reselection allowance, and spare bits. This information is fundamental for the UE to understand the network's configuration and operate accordingly.
explanation: The MIB is classified as a Message because it represents a specific signaling data that is transmitted from the network to the UE, containing critical system information necessary for the UE's operation within the network.
