Path loss in LTE

Hi Friends,

As we know, UE calculates DL path loss based on Ref signal power Tx’ed by NW (from SIB2, RRC setp/RRC reconfig). In similar way, is there a way NW calculates UL path loss? or NW doesnt need to know UL path loss? Thanks in advance

I guess in the Uplink, network use Power Control and Link Adaptation to accomodate channel condition.

@Rajendra_T - UL path loss or UL channel estimation is done by DMRS and SRS. SRS is optional but DMRS are always used with PUSCH/PUCCH.
With this ul channel estimation N/w find out how much ul signals is distorted/shifted/lossed.
