- B. False
Answer: A
NEW QUESTION 12
LTE establishment cause when carrying terminal access network, which of the following description is wrong?
- A. The reason for the establishment of the service request carried by the UE is Mo-data.
- B. The reason for the establishment of the Attach request is Mo-signalling.
- C. The reason for the establishment of the TAU process is Mo-data.

Answer: C
NEW QUESTION 13
Regarding the scheduler, what are the correct descriptions of the following?
- A. Based on different types of business carried on the PPSCH, the scheduling modes on the PDSCH are divided into semi- static scheduling and dynamic scheduling.
- B. Semi-static scheduling is mainly used for VoIP services. Considering that VoIP services have high latency requirements, although they belong to data scheduling, they have higher priority than broadcast and paging.
- C. The semi-static scheduling resource configured by the PDCCH is required to be dynamically scheduled to ensure the quality of the service before the resource is released.
- D. The uplink can support TTIBUNDLING, and several bound TTIs are processed as the same resource to obtain the uplink HARQ combining gain.
Answer: A,C
NEW QUESTION 14
The eNodeB filters the edge UE according to the measurement report of which event that the UE reports?

NEW QUESTION 15
AS security procedures, MME issued key, view messages, in which of the following messages exist encryption algorithms and security key?
- A. None of the above
- B. Authentication information Answer (HSS sent to MME)
- C. Security Mode Command (MME sent to UE)

NEW QUESTION 16
Which of the following is wrong about the TDM eICIC statement?
- A. TDM eICIC is a HetNet interference coordination solution
- B. The microcell schedules interference UE in the normal subframe of the macro station
- C. ABS (Almost Blank Subframe) refers to not transmitting user specific PDCCH and PDSCH on certain subframes of a cell, because these two types of channels occupy most of the resources (CCE and RB) of each subframe, so Such a subframe is called an ABS subframe.
- D. The microcell schedules interfering UE in the macro station ABS subframe
Answer: D
NEW QUESTION 17
Which of the following descriptions is correct?
- A. If the user's default APN is signed as the IMS APN in the HSS, the data APN is non-default, which will cause the user to activate the first default bearer with IMSIPN in all scenarios.
- B. There are default bearers and dedicated bearers in LTE. Voices for VoIP must use dedicated bearers.
- C. In the Attach request, the UE will report the LTE voice capability (whether CSFB or VoIP is supported) to the MME.
- D. The attach type initiated by the VoLTE user is EPS-attach, and the attach type initiated by the CSFB user is combined attach.
Answer: C
NEW QUESTION 18
The "average number of uplink PRB resource usage" counts the number of RBs used by the uplink PUSCH.
- A. True
- B. False
Answer: A
NEW QUESTION 19
Which of the following messages contains UE history information?
- A. SN Status Transfer
- B. Path Switch Req
- C. RRC Connection Reconfiguration
- D. Handover Request
Answer: C
NEW QUESTION 20
About TDD and FDD contrast description, which is correct?
- A. LTE TDD is a time division system. When the terminal is allocated the same number of RB, the LTE TDD throughput rate is lower than the LTE FDD.
- B. For 20MHz bandwidth cell, the FDD uplink and downlink each occupy 20MHz, and the TDD uplink and downlink share 20MHz.
- C. Since the LTE TDD in GP present in such LTE TDD spectral efficiency slightly lower than LTE FDD.
- D. The subframe ratio of LTE TDD makes the delay of some information feedback (such as HARQ ACK/NACK, or CQI) less than the delay of LTE FDD. Therefore, the RTT (Round-trip Time) of LTE TDD is slightly smaller than LTE FDD.
Answer: B,C,D
NEW QUESTION 21

- A. Antenna height
- B. Antenna direction angle antenna downtilt angle
- C. Antenna type
Answer: C

- A. Time to Triger changed from 320ms to 640ms
- B. Time to Triger changed from 320ms to 120ms
- C. Set the value of Ocs in the A cell to be smaller.
- D. Set the CIO (Ocn) value of the B cell to be larger
Answer: B,C,D
NEW QUESTION 23
Regarding the NB-IoT downlink residual error rate, what are the correct descriptions below? (Multiple Choice)
- A. The greater the number of HARQ retransmissions, the worse the indicator
- B. The network management system can separately count according to different coverage levels.
