MIB (Master Information Block) in 5G

Introduction to Master Information block 

The Master Information Block (MIB) is the first part of a 5G network connection. It contains basic network parameters, such as cell information, security key, and authentication common information. The MIB is used to provide keys and access for subsequent applications. A Master Information Block (MIB) is a 5G NR MIB, which may be used to identify the arrangement and type of allocation of radio resources in the uplink and downlink subframes. The MIB is anticipated to provide information on the available radio resources and it also carries information about how/when the radio resources will be shared with other users. The Master Information Block (MIB) is a new signaling block that enables user equipment (UE) and network entities to discover, interpret and use each other's capabilities and services. The MIB is being defined by 3GPP in order to support the evolution from 4G LTE to 5G. The Master Information Block (MIB) is designed to inform the network about the capabilities of the UE and its access. 

The MIB contains critical system parameters that allow the eNB to operate efficiently and effectively. It also contains hardware-related measurements that are needed for radio resource management, Channel Quality Indication (CQI) reports, and Higher layer measurement information. A Master information block (MIB) is a key part of the control plane protocol in a 5G network. In 3GPP R10, the MIB is specified as a leaf node below the top-level CP MIB module ( Control plane Measurement Point (CPMP)) and its format is defined by source code. The source code defines a set of functions used to retrieve the data defined for MB ( Master information block), and its referencing address to access other fields such as RI(Reporting Interval), RARFCN(Reporting Area Reference Frequency Channel Number), etc. It consists of two parts: user plane measurement point and user plane data type definitions. The Master Information Block (MIB) is a new layer that has been added to the existing protocol stack of 5G systems. It serves as a carrier for the provisioning of system parameters, QoS, and security features required by applications, including non-standardized ones. 

The MIB is based on PDUs (Protocol Data Units), which are all defined in Internet documents so that they can act as building blocks for developing new protocols.

In a wireless communication system, a master information block (MIB) may be defined as the first information element in a message. A MIB is generally used to convey system static parameters. Due to the introduction of 5G, there will be a lot of construction on wireless communication. The wireless access network has been updated with new features and services. This leads to a need to improve the quality of service and user experience. The Master Information Block (MIB) is the highest-priority data block in the 5G network. With its legacy from LTE and earlier networks, the Master Information Block (MIB) not only informs 5G mobile devices about their current state but also about their neighbors. 

At a very high level, this is what MIB does: - Provides information about the cell security key and access point capabilities - Provides network information such as frequency settings, handover parameters, and duplex modes - Points to other important blocks of information related to system capabilities required by higher layers and applications. The Master Information Block (MIB) is a flexible, extensible segment of the 5G system that serves as a foundation for mobile networks. The MIB enables wireless platforms to attach to multiple network domains, and can be used within any service provider infrastructure and radio access network. The Master Information Block (MIB) is a data block that carries the essential information about the radio bearer, physical channel, and transport channel of the 5G New Radio (NR) network. The MIB conveys information such as carrier frequency, bandwidth, modulation, coding rate, and access control parameters of 5G NR.
