The different sublayers used in  Radio Protocol Architecture are: Medium Access Control (MAC), Radio Link Control (RLC), Packet Data Convergence Protocol (PDCP) and Service Data Adaptation Protocol (SDAP), Radio Resource Control (RRC) and Non-Access Stratum (NAS). Where:

-The physical layer offers to the MAC sublayer transport channels;

-The physical layer offers to the MAC sublayer transport channels;

-The MAC sublayer offers to the RLC sublayer logical channels;

-The RLC sublayer offers to the PDCP sublayer RLC channels;

-The PDCP sublayer offers to the SDAP sublayer radio bearers;

-The SDAP sublayer offers to 5GC QoS flows;
