Owing to its inherent single carrier structure, a prominent advantage of SC-FDMA over OFDM and OFDMA is that its transmit signal has a lower peak-to-average power ratio (PAPR) , resulting in relaxed design parameters in the transmit path of a subscriber unit.
Read moreWhat is the difference between OFDM and SC-FDMA?
The most obvious difference between the two schemes is that OFDMA transmits the four QPSK data symbols in parallel, one per subcarrier, while SC-FDMA transmits the four QPSK data symbols in series at four times the rate , with each data symbol occupying a wider M x 15 kHz bandwidth.
Read moreWhat is DFT spread OFDM?
The DFT-spread OFDM is a form of single-carrier technique that possesses almost all advantages of the multicarrier OFDM technique (such as high spectral efficiency, flexible bandwidth allocation, low sampling rate, and low-complexity equalization).
Read moreWhat is resource block group?
First it divides resource blocks into multiples of groups. This resource block group is RBG(Resource Block Group) called. The number of resource block in each group varies depending on the system band width. It means RBG size gets different depending on the system bandwidth. … Resource Allocation Type.

Read moreWhat is RBG LTE?
In Resource Allocation Type 0, Resource Block assignment information includes a bitmap indicating a set of Resource Block Groups (RBGs) to the scheduled UE. An RBG is a set of consecutive PRBs .
Read moreWhat is RB and PRB in 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 resource allocation type in 5G?
Resource Allocation Type specifies the way in which the scheduler allocate resource blocks for each transmission . Just in terms of flexibility, the way to give the maximum flexibility of resource block allocation would be to use a string of a bit map (bit stream), each bit of which represent each resource block.
