LTE for UMTS - OFDMA and SC-FDMA Based Radio Access
For uncoordinated deployment (unsynchronized) on the same frequency band,
the devices connected to the cells with different timing and/or different uplink/
downlink allocation may cause blocking for other users. In LTE TDD the base
stations ...

These calculations help in defining the cell ranges along with the coverage
thresholds. Coverage threshold is a downlink power budget that gives the signal
strength at the cell edge (border of the cell) for a given location probability. As the
link ...

Digital Mobile Communications and the TETRA System
the downlink usage marker and the second field contains the uplink usage
marker. If the downlink is not assigned, both fields can be used for access fields
and so different access rights can be given for each uplink subslot. However, if
the ...

Handbook of Electrical Engineering Calculations
On the Ku-band downlink, heavy rain can cause significant attenuation. We can
calcualte the uplink and downlink margins from the overall C/N formula, by
allowing the uplink C/N and the downlink C/N to fall to a value which reduces the
...

Satellite Communications Systems Engineering: Atmospheric ...
The OBP satellite, also called a regenerative satellite or a smart satellite,
provides two essentially independent cascaded communications links for the
uplink and downlink. Figure 9.8 shows a schematic block diagram of the on-
board ...

UMTS Network Planning, Optimization, and Inter-Operation ...
The analysis of capacity and interference on the downlink side is significantly
more complicated due to the fact that the relevant coverage and interference
parameters would vary depending on the location of the mobile within the cell.
However ...
