The main objective behind SRS-configuration is to get uplink channel estimation feedback from the UE for different region in frequency domain. This is mainly required by eNodeB to allocate the uplink radio resources in better region of frequency domain.

Hi harshita.

Thanx for the information .. So what I understood is using the srs from the UE, enodeB assigns resources(what does these resources mean - is it Resource elements/PRBs) in the frequency domain for uplink PUSCH .. Now wanted to know does this SRS has any relation to the PHR(power headroom report)sent by UE to enodeB .
