10.3 Functions
10.3.1 Active Channel Measurements
By means of the basic measurement reporting procedure /
GSM:08.58:4.5.1/, the RBS performs quality and signal strength
measurements on all active uplink dedicated channels. Measurements
on channel combinations, (i), (ii), (v) and (vii) are supported, /
GSM:05.02:6.4/.
