In this configuration, a subframe has 16 slots in it, it means a radio frame contains 160 slots in it. The number of OFDM symbols within a slot is 14.
Read moreWhat is resource grid in 5G?
– A resource grid is characterized by one subframe in time domain and full carrier bandwidth in the frequency domain . – There are a set of resource grids per transmission direction (uplink or downlink).

Data then goes through the service data adaptation protocol (SDAP) , a new protocol layer for quality of service (QoS) management. The higher protocol layers are based on LTE. The IP header is replaced with a 5G equivalent at the packet data convergence protocol (PDCP) layer.23 Tem 2020
Read moreWhat is 5G MAC layer?
The MAC sublayer of 5G NR protocol stack interfaces to RLC sublayer from above and PHY layer from below. It maps information between logical and transport channels . Logical channels are about the type of information carried whereas transport channels are about how such information is carried.24 Şub 2021
Read moreWhat is MAC layer in LTE?
The MAC layer supports the functions such as connecting the upper layer with the lower layer, transferring data and controlling radio resource . The MAC layer is composed of a HARQ entity, a multiplexing/de-multiplexing entity, a logical channel prioritization entity, and a control entity.
Read moreHow many PRB is 5G?
In 5G, One NR Resource Block (RB) contains 12 sub-carriers in frequency domain similar to LTE. In LTE resource block bandwidth is fixed to 180 KHz but in NR it is not fixed and depend on sub-carrier spacing.
Read moreWhat is absolute frequency point A?
Absolute frequency position of the reference resource block (Common RB 0). Its lowest subcarrier is also known as Point A . Note that the lower edge of the actual carrier is not defined by this field but rather in the scs-SpecificCarrierList.
