<h2>RX
Level Statistics per TRX (RXLEVEL)</h2>

<p>This measurement shows the RX level in six classes per
RX quality band in both the uplink and the downlink directions.</p>


<p>The measurement consists of 96 counters. There are 48 counters
corresponding to the RX quality bands defined in both the uplink and the downlink
directions.</p>


<p>The incrementing is made according to the number of each
RX level class received by the BSC in the radio link measurement messages.
The RX level is divided into six subclasses in both the uplink and the downlink
measurement and the ranges of classes are set by the user, for example, 0-10,
11-15, 16-20, 21-30, 31-40, 41-63. In the RX level counter incrementing the
missing radio downlink measurement reports and the BTS measurement averaging
parameter are taken into account. If the downlink measurement is missing,
the latest downlink measurement is used. This way the counters will be updated
every 480 ms. Table 1 presents an example of data presentation.</p>

<h2>Link
Balance per MS Classmark Per Cell (LINKBAL)</h2>

<p>This measurement provides the network operator with the
path balance, that is, the imbalance between the uplink and the downlink path
evaluation.</p>


<p>The path balance difference between the uplink and the
downlink path evaluation is divided into 11 subclasses, that is, five subclasses
for negative and positive imbalance and one for balance. The class ranges
will be closer to one another near the balance value 0, and the size of the
class will be 2 dB while at the edge of the path balance range the size of
the class will be 5 dB. The balance values &lt; -20 dB will be considered
as -20 dB, and the balance values &gt; 20 dB will be considered as 20 dB. If
either the mobile station or the BTS reports a RXLEV of 63 (-47 dBm), the
measurement report containing this information should be discarded from use
within this evaluation. The path balance is calculated as a difference between
the signal levels. Path balance = RxLevDL-RxLevUL-Correction. The correction
is calculated as a difference between the sensitivity levels of the BTS and
the MS. Correction = ms_sensitivity - bs_sensitivity. The measurement counters
are incremented every 480 ms. In the statistical report the path balance is
displayed to an accuracy of one BTS or one BSC.</p>


<p>The sensitivity of the MS is:</p>
