Re: PDCCH DL Grant
DL PDCCH Grant is time domain entity
1TTI in LTE =1ms
So in 1 sec we have 1000 TTI or 1000 DL PDCCH Grant which is being shared by multiple users.
While Drive Test if you are achieving grant close to 1000(which meant you are the only user) you will get higher throughput.
Cheers!!!

Re: PDCCH DL Grant
If it is low it means that other users are being scheduled on the same TTIs so the cell is loaded. In the case, you should offload the cell (add capacity, reduce cell coverage, ...)
