Abstract
Subspace codes, i.e., subset of a finite-field Grassmannian, are applied in random linear network coding. Here we give improved upper bounds based on the Johnson bound and a connection to divisible codes, which is presented in a purely geometrical way. This complements a recent approach for upper bounds on the maximum size of partial spreads based on projective $q^r$-divisible codes.
