This paper investigates Gabor frame sets in a periodic subsetof. We characterize tight Gabor sets in, and obtain some necessary/sufficient conditions for a measurable subset ofto be a Gabor frame set in. We also characterize those setsadmitting tight Gabor sets, and obtain an explicit construction of a class of tight Gabor sets in suchfor the case that the product of time-frequency shift parameters is a rational number. Our results are new even if.
