Popis:	A BandWidth part (BWP) corresponds to an allocation of resources in the frequency domain. The initial BWP corresponds to a 5G‐NR sub‐band on which the mobile user equipment (UE): searches for the synchronization signal block. The size of the BWP depends on the number of Physical resource blocks and the numerology. The mobile camps on a cell which broadcasts the SSB block and the system information block type 1 (SIB1) information allowing the mobile to find the configuration of the initial BWP partition. The concept of control resource SET (CORESET) was introduced on the 5G‐NR interface to limit the control frequency domain to the capacities of devices. The configuration of the CORESET is transmitted to the mobile UE via Radio Resource Control messages. The initial BWP is transmitted to the mobile by the broadcast information MIB and SIB1.
