Within NR, the initial-access functionality includes:
- • The functions and procedures by which a device initially finds a cell when entering the coverage area of a system;
- • The functions and procedures by which a device in idle/inactive state accesses the network, typically to request the set-up of a connection and commonly referred to as random access.
