AB  - In this paper, as a continuation of our previous work on the low-lying heavy-light meson spectra, we systematically study the mass spectra and Okubo-Zweig-Iizuka-allowed strong decays of the higher 3S-, 2P-, 2D-, and 1F-wave charmed and charmed-strange mesons within a unified unquenched quark model. It is found that coupled-channel effects induce sizable state dependent mass shifts, which modify the relative level spacings and lower the predicted masses compared with conventional quenched calculations. The newly observed D_s1(2933)^+ reported by the LHCb collaboration could be identified as the low mass axial vector state D_s(2P_1) via the 2^1P_1−2^3P_1 mixing. For the broad structure D_sJ(3040)^+ observed earlier by the \emph{BABAR} collaboration, the D_s(3^1S_0) assignment seems to be favored over the high mass mixed state D_s(2P_1^′). Meanwhile, the D(3000)^0 signals reported by LHCb cannot be consistently explained by any of the considered 3S, 2P, 2D, or 1F assignments. Our predicted masses and decay properties of the missing higher D and D_s mesons may provide useful information for future experimental searches.
