Dear Kanak,
you can do in two ways:

1) do a NSCF or band calculation with only one k-point, then do projwfc 
(repeat for each k-point)

2) do a NSCF or band calculation including those k-points (e.g. for a 
path in the Brillouin zone), then do projwfc.x with kresolveddos=.true.
The PDOS at each k-point will be saved in the *.pdos_atm* files. (see 
espresso-5.4.0/PP/examples/example02 for an example).

Hope this helps.
