VIM remap Ctrl-w SHIFT-[h,j,k,l]

Question

I'm trying to remap in my vimrc the keys Ctrl+w Shift+[H,J,K,L] to Ctrl+Shift+[H,J,K,L]. I'm using gnome vim version 8.1

This is what I have

" Easy window positioning
"nnoremap <leader>h <C-w>H
"nnoremap <leader>j <C-w>J
"nnoremap <leader>k <C-w>K
"nnoremap <leader>l <C-w>L
nnoremap <C-Shift-h> <C-w><Shift-h>
nnoremap <C-Shift-j> <C-w><Shift-j>
nnoremap <C-Shift-k> <C-w><Shift-k>
nnoremap <C-Shift-l> <C-w><Shift-l>
" Easy window navigation
nnoremap <C-h> <C-w>h
nnoremap <C-j> <C-w>j
nnoremap <C-k> <C-w>k
nnoremap <C-l> <C-w>l

If I use the remap with the leader key works ok but is not really how I would like the mapping to be.

The navigation works but the window positioning doesn't.

I would like to be able, if it is possible, to press Ctrl+Shift+[H,J,K,L] to move the panes around the screen.

I've tried:

" Easy window positioning
nnoremap <C-Shift-h> <C-w><Shift-h>
nnoremap <C-Shift-j> <C-w><Shift-j>
nnoremap <C-Shift-k> <C-w><Shift-k>
nnoremap <C-Shift-l> <C-w><Shift-l>
" Easy window positioning
nnoremap <C-Shift-H> <C-w><Shift-H>
nnoremap <C-Shift-J> <C-w><Shift-J>
nnoremap <C-Shift-K> <C-w><Shift-K>
nnoremap <C-Shift-L> <C-w><Shift-L>
" Easy window positioning
nnoremap <C-SHIFT-H> <C-w><SHIFT-H>
nnoremap <C-SHIFT-J> <C-w><SHIFT-J>
nnoremap <C-SHIFT-K> <C-w><SHIFT-K>
nnoremap <C-SHIFT-L> <C-w><SHIFT-L>
" Easy window positioning
nnoremap <C-S-H> <C-w><S-H>
nnoremap <C-S-J> <C-w><S-J>
nnoremap <C-S-K> <C-w><S-K>
nnoremap <C-S-L> <C-w><S-L>
