【资料目录和简介】:



List of detected preambles


The eNB shall report a list of detected PRACH preambles to higher layers. Higher layer utilize this info for the RACH procedure



Transport BLER


The ACK/ NACKs for each transmission of the HARQ process are reported to the MAC. Based on these ACK/NACKs the higher layers compute the BLER for RRM issues.



TA


The eNB needs to measure the initial timing advance (TA) of the uplink channels based on the RACH preamble.



Average RSSI


Measured in UL by eNB. It can be used as a level indicator for the UL power control. The RSSI measurements are all UE related and shall be separately performed for ( TTI intervals)


· UL data allocation (PUSCH)


· UL control channel (PUCCH)


Sounding reference signal (SRS)



Average SINR


In UL the eNB measures SINR per UE. The average SINR can be used as a quality indicator for the UL power control



UL CSI


Channel state information per PRB for each UE. The CSI shall be the received signal power averaged per PRB.
