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.24 Nis 2019
Read moreHow many subframes are there in an LTE frame?
The basic type 1 LTE frame has an overall length of 10 ms. This is then divided into a total of 20 individual slots. LTE Subframes then consist of two slots – in other words there are ten LTE subframes within a frame.
Read moreHow many symbols are in a LTE frame?
Each LTE symbol will be roughly of 67 microseconds and there will be 7 symbols per slot, 14 symbols per subframe and 140 symbols per radio frame . The number & duration of symbols will change, if the system is configured to extended cyclic prefix type.
Read moreWhat is frame length in LTE?
LTE supports two frame lengths, 5 ms and 10 ms . Each 10 ms interval contains 10 subframes, which are labeled in the Table as D for downlink transmission, U for uplink transmission, and S for special subframe. The special subframe contains the turnaround time between downlink and uplink transmissions.
Read moreWhy is the LTE frame 10ms?
So a LTE radio frame consists of 10 subframes (i.e. total 1 ms) in time domain & 72 subcarriers (i.e. total 1080 Khz) in freq domain. Why 15kHz? It is because UMTS and LTE have the same clock timing !
Read moreWhat are transport blocks?
Transport Block is a packet of data which is passed between the MAC and Physical layers . It is passed downwards at the transmitter and upwards at the receiver. A Transport Block undergoes Physical layer processing at the transmitter before being mapped onto the PDSCH for transfer across the air-interface.
Read moreWhat is TB size in LTE?
TB Size(transport block size) defines how many bits MAC layer transfers to Physical layer per TTI (Transmission Time Interval, defined as 1ms). Note: TM1/TM2 can carry 1 TB Size per TTI, TM3/TM4 can carry 2 TB Size per TTI (two code word).
