Can it be Rubus paniculatus ?

This is how the plant is described in FLOWERS OF THE HIMALAYA by Oleg Polunin and Adam Stainton,

“A RAMBLING CLIMBER DISTINGUISHED BY ITS LARGE SIMPLE OVATE-HEART-SHAPED FINELY TOOTHED LEAVES, AND TERMINAL BRANCHED CLUSTERS OF WHITE FLOWERS WITH NARROW PETALS WHICH ARE MUCH SHORTER THAN THE PALE SILKY-HAIRED CALYX-LOBES. FLOWERS 1-1.5 CM ACROSS. LEAVES 8-15 CM. INCLUDING LEAF-STALK OF 2-3 CM. ALL PARTS PLANT EXCEPT THE UPPER SIDES OF THE LEAVES AND OLDER STEMS COVERED WITH A DENSE MAT OF WHITE OR BUFF HAIRS; PRICKLES ABSENT OR FEW.”
