RBS load

The RBS load is defined as the percentage of available RBS power that is used.

The overall assumption for HSDPA dimensioning is that the RBS load is 100%, i.e. all cells are transmitting with full power all the time.

Cell capacity

Cell capacity is defined as the cell throughput in an individual cell.

In a network with inhomogeneous traffic distribution and non-hexagonal cells, the cell capacity may vary depending on amount of traffic in own and other cells and
inter-cell interference.

Cell border throughput

The cell border throughput is defined as the bit-rate a single HSDPA user would get when standing in the cell border area. The cell border throughput is obtained
for the case when only one user is active in the cell.

The cell average throughput is defined as the average expected bit-rate for one
cell. The average is taken for a whole cluster of cells, where the subscribers are
evenly spread over the cell area.
It is possible to take advantage of scheduling gain since there are many users in
the cell. The cell average throughput is the shared throughput for all HSDPA
users that are in the cell. The individual user throughput depends mainly on how
many other users that are connected to the same cell.
