Abstract The incremental redundancy type-II HARQ has been applied into the cross layer design. The closed-form expressions of the packet error rate and average spectral efficiency for the transmissions over Nakagami- channel have been derived. Numerical results show that the type-II HARQ with high complexity could achieve higher spectral efficiency and lower packet error rate compared with the cross layer design system with type-I HARQ. While the type-I HARQ has the lower spectral efficiency and the higher packet error rate, but its complexity is low.
