1/10 Questions

For what reason that UL scheduling is handled based on channel groups?
- To save resource to send BSR
- ENB cannot identify each bearer separate
- Admission control is done per logical channel group so scheduling needs to work in the same way
- To save UE battery power

About This Quiz

This quiz assesses knowledge on LTE eRAN7.0's scheduling features, focusing on UL and DL scheduling mechanisms, resource allocation types, and the impact of CQI on data rates. It is designed for learners to understand advanced technical aspects of LTE networks and enhance their skills in network management.

2.

In DL scheduling, MCS is defined based on reported CQI. It is a procedure to select how much data rate the UE can get which is again only depending on the CQI.
- True
- False
Correct Answer

A. False

Explanation

In DL scheduling, MCS (Modulation and Coding Scheme) is not solely determined by the reported CQI (Channel Quality Indicator). While CQI is an important factor in determining the MCS, there are other factors such as channel conditions, interference levels, and available resources that also influence the selection of MCS. Therefore, it is incorrect to say that MCS is only dependent on the CQI.

3.

Frequency diversity and frequency selective scheduling methods can use the same method for PDSCH resource allocationtypes.
- True
- False
Correct Answer

A. True

Explanation

Frequency diversity and frequency selective scheduling are both methods used for PDSCH (Physical Downlink Shared Channel) resource allocation. Frequency diversity is a technique that uses multiple frequency bands to transmit the same data, improving the reliability of the transmission. Frequency selective scheduling, on the other hand, is a method that assigns different frequency resources to different users based on their channel conditions. Both methods can utilize the same method for allocating PDSCH resources, making the statement true.

4.

Wideband CQI is better than subband CQI since eNB can learn the whole bandwidth.
- True
- False
Correct Answer

A. False

Explanation

Wideband CQI is not better than subband CQI because even though the eNB can learn the whole bandwidth, subband CQI provides more detailed information about specific frequency bands. Subband CQI allows for better resource allocation and interference management, as it provides insights into the quality of specific subbands. Therefore, subband CQI is more beneficial in optimizing network performance compared to wideband CQI.

5.

The worst resource allocation type resource utilization is PDSCH resource allocation type 2.
- True
- False
Correct Answer

A. False

Explanation

The worst resource allocation type for resource utilization is not PDSCH resource allocation type 2.

What factor does not help to define the number of RBs to be allocated to a UE?
- UE capability
- Data in buffer to be sent to the UE
- CQI reported by the UE
- DL PDSCH power that equals to -10log(Pb+1)
Correct Answer

A. DL PDSCH power that equals to -10log(Pb+1)

Explanation

The DL PDSCH power that equals to -10log(Pb+1) does not help to define the number of RBs to be allocated to a UE. The DL PDSCH power is related to the power level of the downlink physical shared channel, which is used to transmit data to the UE. However, the number of resource blocks (RBs) allocated to a UE is determined by factors such as the UE capability, the amount of data in the buffer to be sent to the UE, and the CQI (Channel Quality Indicator) reported by the UE.

7.

Frequency selective scheduling may result in not fully used resources.
- True
- False
Correct Answer

A. True

Explanation

Frequency selective scheduling is a technique used in wireless communication systems to allocate different frequency bands to different users based on their channel conditions. However, this technique can result in not fully utilizing the available resources because certain frequency bands may not be used efficiently due to interference or poor channel conditions. Therefore, the statement that frequency selective scheduling may result in not fully used resources is true.

8.

If UE has some data in its buffer but there is no UL resource assigned. Scheduling Request (SR) must be sent.
- True
- False
Correct Answer

A. True

Explanation

If a user equipment (UE) has data in its buffer but no uplink (UL) resource has been assigned to it, the UE must send a Scheduling Request (SR). This is because the UE needs to request the allocation of UL resources from the network in order to transmit its buffered data. Therefore, the statement "True" is correct.

Rate this question:
9.

MCS selection in both UL and DL is based on CQI reported by a UE.
- True
- False
Correct Answer

A. False

Explanation

The statement is false because MCS (Modulation and Coding Scheme) selection in the UL (Uplink) is based on the CQI (Channel Quality Indicator) reported by a UE (User Equipment), but in the DL (Downlink), MCS selection is not solely based on CQI. In the DL, MCS selection is also influenced by other factors such as channel conditions, interference, and the desired data rate. Therefore, the statement is incorrect as it implies that MCS selection in both UL and DL is solely based on CQI.

Rate this question:
10.

If the Min-GBR of non-GBR services is greater than the PBR, the service rate may not reach the Min-GBR.
- True
- False
Correct Answer

A. True

Explanation

If the Minimum Guaranteed Bit Rate (Min-GBR) of non-GBR services is higher than the Peak Bit Rate (PBR), it means that the non-GBR services are guaranteed a minimum rate of data transmission that is higher than the maximum rate they are allowed to reach. This implies that the service rate may not be able to reach the Min-GBR because it is limited by the PBR. Therefore, the statement is true.
