UMTS Frame Structure

UMTS Frame structure

Figure depicts UMTS frame structure for 3.84Mcps radio system. It is made of super frame, radio frame and chips. Each radio frame is of duration 10ms and composed of 15 slots. Each slot is composed of 2560 chips. Chip duration is about 0.26micro-sec (derived from 1/3.84Mcps). Slot duration is about 0.667ms.

Refer frame structure of other standards as mentioned below.
