<h2>Power Control</h2>

<p>Uplink power control is managed with a formula</p>


<p>P<sub>CH</sub> = min(Γ<sub>0</sub> - Γ<sub>CH</sub> - α*(C
+ 48),PMAX) (1)</p>


<p>The operator is given cell specific parameters α and Γ<sub>CH</sub>
used in formula (1). </p>


<p>Γ<sub>CH</sub> ("gamma_ch" in the figure) determines the
minimum MS output power and α ("alfa") determines the slope by which the downlink
RX_LEVEL affects the power.</p>

</div>


<p>Downlink power control support is not supported by the
current BSS release. This is a feature candidate for a future BSS release. </p>


<p>The power of each block needs to be sufficient for two
MSs:</p>


<p>The MS receiving the data</p>


<p>The MS receiving the USF flag (Uplink State Flag, determines
uplink transmission turn in case several mobiles have been assigned to the
same uplink PDTCH.)</p>
