This paper studies the online Orthogonal Variable Spreading Factor (OVSF) code assignment problem with resource augmentation introduced by Erlebach et al. in [8]. We propose a (1 + ε)-competitive algorithm with help of (1+⌈1/ε⌉) lg*h trees for the height h of the OVSF code tree and any constant 0 h trees, which substantially improves the previous resource of 3h/8 + 2 trees shown by Chan et al. in [2].
