A frame has duration of 10 ms which consists of 10 subframes having 1ms duration each similar to LTE technology . Each subfame can have 2μ slots. Each slot typically consists of 14 OFDM symbols.
Read moreWhat is physical layer in 5G NR?
PHY layer sits at the bottom of the 5G NR protocol stack, interfacing to MAC sublayer higher up via transport channels . It provides its services to MAC and is configured by RRC . PHY supports downlink ( gNB -to- UE ), uplink ( UE -to- gNB ) and sidelink ( UE -to- UE ) communications.

5G NR Numerology – Subcarrier Spcaing (SCS)
Read moreWhat is layer in 5G NR?
The 5G NR radio access network is comprised of these protocol entities: Service data adaptation protocol (SDAP) Packet data convergence protocol (PDCP) Radio link control (RLC) Medium access control (MAC)
Read moreWhat does 5G NR means?
5G New Radio (NR) is the global standard for a unified, more capable 5G wireless air interface. It will deliver significantly faster and more responsive mobile broadband experiences, and extend mobile technology to connect and redefine a multitude of new industries.
Read moreWhat is PDCP discard timer?
A PDCP layer sets a timer and discards a PDCP SDU upon expiration of the timer . The timer may be set upon receiving the PDCP SDU from an upper layer or upon submitting the PDCP SDU to a lower layer for transmission. The timer and a radio link control (RLC) discard timer may be coordinated.
Read moreWhat is the use of PDCP protocol?
PDCP is located in the Radio Protocol Stack in the UMTS/LTE/5G air interface on top of the RLC layer. PDCP provides its services to the RRC and user plane upper layers , e.g. IP at the UE or to the relay at the base station.
