Please answer, thank you :)

Extracted text: 1. (True or False) The 5G air interface is based on the new waveform of F-OFDM, and uses a fixed subcarrier bandwidth of 15KHZ to resist stronger interference. True False 2. (True or False )5G NSA network architecture facilitates rapid deployment of 5G services based on 4G network by aggressive telecom operators. True False 3. (True or False) In the 5G EMBB scenario, the LDPC Code is used for control channel coding, and the Polar Code is used for traffic channel coding. True False 4. (True or False) 5G is a broadband communication system. Considering the variety of 5G service scenarios, the terminal types must also be very rich. For some service terminals with low rate requirements, you can use BWP (Bandwidth Part) technology to reduce terminal cost and power consumption. True False 5. (True or False) Based on the light coupling requirements of the operator's network, the 5G backhaul network and the 4G backhaul network are completely isolated, and no interconnection is required. True False 6. (True or False) In the 5G NR, the modulation mode is 256QAM for the physical uplink control channel PUCCH. True False 7. (True or False) If the EPC+ of the Option 3 of the 5G networking solution adopts the NFV-based cloud architecture, it can be upgraded to 5GC that supports Option 2 networking. True Flase 8. (True or False) The RAN centralized unit(CU) is also commonly referred to.as the RAN real-time processing unit. True False 9. (Single-choice) what kind of changes in the 5G network will not bring new demands to the IP transport bearer network? a. NFV in core network b. CU-DU separation in Base station c. Deploy MEC close to base station d. Baseband unit centralization in base station 10. (Single-choice) If you are making a slice design for the lot meter services, which of the following functions can be cut off? a. Billing function b. Mobility management function c. Session management function d. Terminal management function
