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…

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…

In UL, the UE has no dedicated resources to transmit directly when new data arrived in the buffer from higher layer.  It requests resources to transmit them.  It receives radio…
