  In the framework of the littlest Higgs model with $T$ parity, we study the
$W_H/Z_H+q_-$ and $W_H$-pair productions at the CERN Large Hadron Collider up
to the QCD next-to-leading order (NLO). The kinematic distributions of final
decay products and the theoretical dependence of the cross section on the
factorization/renormalization scale are analyzed. We adopt the PROSPINO scheme
in the QCD NLO calculations to avoid double counting and keep the convergence
of the perturbative QCD description. By using the subtraction scheme, the QCD
NLO corrections enhance the leading order cross section with a K-factor in the
range of $1.00 \sim 1.43$ for $W_H(Z_H) q_-$ production process, and in the
range of $1.09 \sim 1.22$ for the $W_H$ pair production process.
