A vector generalization of the system of equations (0.1) first obtained by one of
the authors (V.G.M.) is studied. The vector generalization of the system (0.1) is derived
from the multicomponent XXZ Heisenberg model. The Hamiltonian structure is discussed.
We obtain some exact single-soliton (regular and singular) solutions to the
$U(p, q)$ system (0.1) and associated $U(N)$ nonlinear Schrödinger equation and Zakharov
system of equations. For the case of $U(2)$ and $U(1.1)$ versions, existence regions of
one-soliton solutions in the $(\alpha,\beta)$ plane are found. Finally, we get a generalization of
the $U(p, q)$ system (0.1) taking into account the spin-spin interaction and obtain its
exact soliton-like solutions. For certain solutions obtained the energy spectrum is calculated.
