2.3.3 Guided Hard Handover (Pilot Beacon Functionality)
The RRH has to be able to generate a pilot beacon signal in order to guide the hard
handover.
The guided hard handover is accomplished by a pilot beacon generated by the RRH.
A typical realization of the guided hard handover from/to 5 outdoor carriers to/from one
dedicated indoor carrier is shown in Figure 11.
Figure 11 Illustration of a typical in-building deployment scenario with pilot beacons
One RRH is able to provide up to 7 adjacent pilot beacon signals simultaneously.
The RRH can either generate one or more pilot beacons or operate on a
communication channel; the switch between the configurations is done by NMS.
The pilot beacon configuration is realized via NMS.
Output power level of the pilot beacon(s):
o The Nominal output power level per pilot beacon is: -20dBm ± 1dB.
o It is adjustable from +14dBm to -50dBm in 1dB steps composite.
o The beacon power level depends on the number of beacon signals.
Configurable parameters via NMS:
o CDMA frequency band and channel per pilot beacon.
o PN offset (0 to 512), same for all pilot beacons per RRH.
o Power level is the same per beacon.
