摘要： A method of a user equipment (UE) in a wireless communication system supporting a shared spectrum channel access is provided. The method comprises: receiving, from a base station (BS), a set of higher layer parameters including a subcarrier spacing of a physical random access channel (PRACH) preamble, a logical root index (ilog) for the PRACH preamble, and an index (zeroCorrelationZoneConfg); determining a sequence length (LRA) for the PRACH preamble based on the subcarrier spacing of the PRACH preamble; determining a physical root index (iphy) for the PRACH preamble based on the logical root index (ilog); determining a cyclic shift (NCS) for the PRACH preamble based on the index (zeroCorrelationZoneConfg); generating the PRACH preamble based on the determined sequence length LRA, the determined physical root index iphy, and the determined cyclic shift NCS; and transmitting, to the base station (BS) over the shared spectrum channel, the PRACH preamble.

摘要： In a time data display mode, a time data is displayed in at least one display block partially assigned to a touch screen of an electronic device. After the touch gesture or the drag gesture is detected in one of the display block, the current time data in the display block can be replaced with a new time data according to the touch gesture or the drag gesture. The new time data may be a following time data or a previous time data which can be determined according to a location of the touch gesture, or a direction and a distance of the drag gesture. In addition, the extent of a change in the time data may be determined according to duration of the touch gesture or a speed of the drag gesture.
