Uplink data transmission in LTE The mapping of transport channels and UL control information (UCI) to physical channels is a task of the physical layer (PHY). Furthermore reference signals are…

What is SC-FDMA and how it works in LTE? One of the major drawbacks of an OFDMA system is, that the transformation of a complex symbol mapped sequence (e.g. BPSK,…

Radio Protocol Architecture in LTE The EUTRAN radio protocol model specifies the protocols terminated between UE and eNB. The protocol stack follows the standard guidelines for radio protocol architectures (ITU-R…

Physical Channel Types of LTE The physical layer uses resource blocks to transmit binary coded information in QPKS, 16QAM or 64QAM or OOK modulation form. Physical channels determine how data…

How Transport Channel Processing in LTE? Transport channels are block oriented transmission services and transmit one or more transport blocks per transmission time interval (TTI). The TTI is 1 ms…

Resource Block & Physical Resource Block in LTE What is Resource block in lte? :- A resource block is the smallest unit of resources which allocated to a user. The…

Benefits of SC-FDMA Receiver in LTE Low Peak-to-Average Power Ratio (PAPR): SC-FDMA (Single-Carrier Frequency Division Multiple Access) exhibits a lower PAPR compared to other modulation schemes, reducing the demand for…

OFDMA Principles in LTE Orthogonal Frequency Division Multiple Access (OFDMA) is a key technology used in Long-Term Evolution (LTE) to efficiently manage the transmission of data over the radio interface….

Single User and Multi User MIMO codewords in LTE Figure shows how the two codewords are used for a single user in the downlink. It is also possible that the…

What is the difference between 4G and 4G LTE? Many people use the terms 4g and 4g interchangeably, but they are not the same. Lets find out the difference…. Features…
