In LTE (Long-Term Evolution) networks, PUCCH (Physical Uplink Control Channel) and UCI (Uplink Control Information) are essential components that facilitate the transmission of control information from the User Equipment (UE) to the base station, known as the evolved NodeB (eNB). Let’s explore in detail what PUCCH is and how it is used to carry UCI: ... Read more
LTE (Long-Term Evolution) is referred to as having a “flat architecture” due to its streamlined and simplified network structure compared to previous generations of wireless networks. The term “flat” signifies a departure from the more hierarchical and complex architectures of previous generations like 2G and 3G. Let’s delve into the characteristics that make LTE a ... Read more
