Lte Eran7.0 Scheduling Feature

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.

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.

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.

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.

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.

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

UL scheduling is handled based on channel groups in order to save resources when sending BSR (Buffer Status Report). By grouping channels together, the eNB (evolved NodeB) can efficiently manage and allocate resources for multiple bearers. If each bearer were treated separately, it would require more resources and overhead to send individual BSRs. Therefore, by scheduling based on channel groups, the eNB can optimize resource allocation and minimize the impact on network performance.

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.

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.
