In E-UTRAN multiple co-located carriers will
typically be deployed requiring efficient inter-frequency (IF)
handover procedures and algorithms for retaining service
quality, better coverage and load balancing between the carriers.
Five IF handover criteria using RSRP, RSRQ or combination
thereof are investigated in synchronous and asynchronous EUTRAN
deployment scenarios. The results depict that an IF
handover solely based on RSRP significantly increases number of
handovers. Conversely the handover criterion based only on
RSRQ reduces handovers but it slightly increases the packet loss
rate. The overall best performance is achieved with the combined
handover criterion, which uses both RSRP and RSRQ and thus
guarantees that the received pilot strength as well as the signal
quality stays within the desired limit after the handover.
