Channel Measurements
The measurements of signal strength are referred to the RX reference
point. An R.M.S. value is formed for each timeslot. The logarithm of
this value, expressed in dBm, is coded as defined for RXLEV in /GSM
05.08:8.1.4/. The average value is calculated from the RXLEV value,
After Initiation, a first average value is calculated after two completed
measurement periods. The second value is calculated when the first
averaging period is completed.
After this, a new average value is calculated after each new
measurement, that is a sliding window principle is used where the
oldest value within the averaging period is replaced by the new one.
The average value is classified into one of five Interference Level Bands.
Results from idle channel measurements are reported via the Abis
message RF_RESOURCE_INDICATION /GSM 08.58:8.6.1/. This is
done when the first value has been calculated and thereafter when the
calculated average value is classified into a new Interference Level
Band.
23.4 Operational Conditions
The measurements of R.M.S. signal level fulfil the requirements in /
GSM:05.08:8.1.2/. When applicable, exceptions are stated within the
context of Radio Reception.
The measurements of RXQUAL fulfil the requirements in /GSM
05.08:8.2/, that is for BER from < 0.2 % to > 12.8 %.
The MEASUREMENT_RESULT message and the
RF_RESOURCE_INDICATION message are sent during the following
reporting period.
