Abstract: The present application relates to a method of generating a downlink frame. The method of generating the downlink frame includes: generating a first short sequence and a second short sequence indicating cell group information; generating a first scrambling sequence and a second scrambling sequence determined by the primary synchronization signal; generating a third scrambling sequence determined by the first short sequence and a fourth scrambling sequence determined by the second short sequence; scrambling the short sequences with the respective scrambling sequences; and mapping the secondary synchronization signal that includes the first short sequence scrambled with the first scrambling sequence, the second short sequence scrambled with the second scrambling sequence and the third scrambling sequence, the second short sequence scrambled with the first scrambling sequence and the first short sequence scrambled by the second scrambling sequence and the fourth scrambling sequence to a frequency domain.

Abstract: Disclosed are a polyamide resin composition that includes (A) a crystalline polyamide mixed resin including an aliphatic group and at least two different crystalline polyamide resins, (B) a non-crystalline polyamide resin including an aromatic group, and (C) a glass fiber, and a molded product manufacture using the same.

Abstract: A glass fiber-reinforced polyester resin composition including: (A) about 30 to about 80 wt % of two or more kinds of polyester resin; (B) about 20 to about 70 wt % of a vinyl-based copolymer including an acrylic-based graft copolymer, a rubber modified vinyl-based graft copolymer, a copolymer of aromatic vinyl monomers and unsaturated nitrile monomers, or a combination thereof; and (C) about 10 to about 100 parts by weight of glass fiber, based on about 100 parts by weight of the total amount of the polyester resin (A) and the vinyl-based copolymer (B), wherein the polyester resin includes polyethylene terephthalate resin having crystallinity of about 40% or more, is provided.
