Uplink Power Control Calculation in LTE
Uplink Power Control Calculation in LTE Transmit power of PUSCH in subframe i is defined by PPUSCH (i) = min{PMAX,10 log10 (MPUSCH (i)) + PO_PUSCH ( j) +α ( j)…

X2 interface Function in LTE – A Connection between Two eNodeBs
The X2 interface is the interface between the eNodeBs. X2 interface protocol stack is described in Figure. X2 Interface performs the following functions: X2-UP (User Plane) X2-CP (Control Plane) LTE…
Open loop and close loop testing in LTE
Here I write short notes on how to test open loop and close loop testing in lte and what idea behind it. In open loop no any data send back…
Closed Loop Mode Transmit Diversity in UMTS
UMTS Closed Loop Mode Transmit Diversity Used in DPCH and HS-PDSCH. The closed-loop-mode transmit diversity can only be applied to the UMTS downlink channel if there is an associated UMTS…
Definition of Front to Back Ratio for LTE antenna
Front to back ratio is an important characteristic of directional antenna antenna. Is the ratio of power radiated from a corner with maximum radiation radiation levels at 180 degrees (the…
