C. The RSRP received by the UE is increased by six dB.
D. The RSRP received by the UE is increased by three dB.

B. The AIR replaces the digital/baseband unit.
C. The AIR in an LTE system is directly connected with the MME using the SI interface.
D. The AIR can replace the standard RU/RRU and antenna.
Which two statements correctly describe Single Carrier Frequency Division Multiple Access (SC-FDMA) as used in LTE systems using uplink SIMO? (Choose two.)
A. SC-FDMA allows simultaneous uplink transmissions on the same physical resource blocks.
B. SC-FDMA is beneficial because it avoids (nter-cell interference.
C. SC-FDMA separates uplink transmissions in the time and/or frequency domain.
D. SC-FDMA is beneficial because it avoids intra-cell interference.
Review the exhibit.
A new residential area has recently been built showing a lack of 3G uplink coverage as shown in the exhibit. The terrain is flat and all the buildings in the area are 20 meters in height with no other relevant direct obstacles.

A. Increase the CPICH power.
B. Increase the electrical downtilt.
C. Reduce the antenna height.
D. Change the azimuth.
What are two benefits provided by the introduction of GPRS/EGPRS Downlink Power Control in a GSM network? (Choose two.)
A. reduced power consumption in RBS
B. reduced downlink Interference levels In the system
C. reduced uplink interference levels in the system
D. increased PS accessibility
