LTE Control Plane and User Plane Latency Calculation (FDD)

March 31, 2019

LTE- is designed to support peak data rates of 300 Mbps in the downlink  and 75 Mbps in the uplink with 4×4 MIMO support along with C-Plane latency  less than 100ms  and U-Plane latency less than 10ms. Latency is defined as the average time between the transmission of packet and the reception of an acknowledgment. […]

Narrow Band-Physical Broadcast Channel (NPBCH)

January 31, 2019

NPBCH stands for narrowband physical broadcast channel similar to PBCH in LTE Technology. The Narrow Band-Physical Broadcast Channel (NPBCH) is used to deliver the NB-IoT Master Information Block (MIB), which provides essential information for the NB-IoT UE to operate in the NB-IoT network. Narrow Band-Physical Broadcast Channel (NPBCH) uses a 640 ms TTI, but within […]
