About the related concepts of carrier aggregation, which description are correct? (Multiple Choice)
- A . The primary cell is the cell in which the CA UE resides, that is, the PCell. The operation of the CA UE in this cell is no different from other R8/9 cells, only the PCell has the PUCCH channel.
- B . A secondary cell refers to a cell that is configured to a CA UE by using RRC connection signaling, and operates on a secondary carrier to provide more radio resources for the CA UE. SCell only has a down line and no uplink
- C . Component carrier refers to the carrier corresponding to different cells participating in carrier aggregation
- D . PCC anchor point, which refers to the high priority resident PCC selected by the eNodeB
About the statement of IRATHO, which are correct? (Multiple Choice)
- A . The HUAWEI eNodeB supports differentiating target system (UTRAN system or GERAN system) to set different event A2 parameters, so as to preferentially trigger the coverage-based switching purpose to the UTRAN system or the GERAN system.
- B . When the thresholds of the UTRAN and the GERAN are the same, the eNodeB sends down two different system events A2, which correspond to different systems. When the UE reports the event A2 of the corresponding system, the eNodeB sends down the heterogeneous system measurement of the corresponding system.
- C . When the threshold offsets of the UTRAN and GERAN systems are the same, the eNodeB sends down a distinct system event A2, which does not distinguish the system. When the UE reports the event A2, the eNodeB simultaneously sends down the UTRAN and GERAN system measurements.
- D . When the base station receives the blind A2 event of the different frequency system, if the sub-switch EmCInterFmqBlindHoSwitch in the parameter CeIIHoParaCfg.CellHoAlgoSwitch is turned on, the different system redirection process based on the measurement report is directly executed.
Which of the following types of mobile phones can support up to 2CC (two carrier aggregation)?
- A . Category 4

- D . Category 10
Which of the following can be considered as good for testing the wireless environment in an LTE system?
- A . RSRP=-90dBm, SINR=11dB
- B . RSRP=-95dBm, SINR=17dB
- C . RSRP=-85dBm, SINR=3dB
- D . RSRP=-75dBm, SINR=25dB
Regarding the description of RRC establishment success rate, which of the following options is wrong?
- A . Reflecting the UE’s admission capability of the eNB or the cell
- B . The successful establishment of the RRC connection means that the UE establishes a signaling connection with the network.
- C . RRC connection establishment can be divided into two cases: one is the RRC connection establishment related to the service; the other is the RRC connection establishment irrelevant to the service (such as emergency call, inter-system cell reselection, registration, etc.)
- D . Service-Independent RRC connection establishment is an important indicator to measure the call completion rate. The service-related RRC connection establishment can be used to investigate the system load situation.
