Abstract: A method and device are disclosed from the perspective of a second User Equipment (UE) to configure Sidelink (SL) Discontinuous Reception (DRX). In one embodiment, the method includes the second UE initiating or initializing a sidelink service with a first UE. The method also includes the second UE determining a SL DRX configuration based on association between sidelink service and SL DRX configuration, wherein the SL DRX configuration is associated with the sidelink service. The method further includes the second UE monitoring sidelink control channel based on the SL DRX configuration.

Abstract: A method and apparatus are disclosed. In an example from the perspective of a first device, a grant is received from a network node. The grant allocates a set of sidelink data resources. One or more sidelink data transmissions are performed on the set of sidelink data resources. A second feedback information associated with the one or more sidelink data transmissions is received and/or detected. An uplink resource is derived. A first feedback information is transmitted on the uplink resource to the network node. The first feedback information is set based upon the second feedback information.

Abstract: A method for detecting a vehicle type, a vehicle speed and width of a detecting area by a vehicle radar sensor is disclosed. A radio wave is transmitted to a tracked vehicle. Subsequently, the reflective radio wave from the vehicle is received. The Doppler frequency versus time distribution is generated from the reflective radio wave. Because the reflective radio wave is influenced by the Doppler Effect, a parallelogram or a shape close to a parallelogram of a consecutive motion diagram is shown in the Doppler frequency versus time distribution of the vehicle. According to the consecutive motion diagram, certain information, such as the length and speed of the tracked vehicle and the width of the detecting area, can be acquired.

Abstract: The invention provides a method for identification of traffic lane boundary. Firstly the microwave signal is received, and the noise reduction is treated for the microwave signal. Then the frequency domain information is employed to calculate the legal set of closed interval, in order to form the frequency span information. Finally, the probability density function model is employed to calculate the frequency span information in order to identify the traffic lane boundary.

Abstract: A retainer for a hanger frame includes an outer sleeve and an inner sleeve mounted in the outer sleeve. The outer sleeve has an inner diameter that gradually decreases from an intermediate portion thereof toward two ends thereof. The inner sleeve includes a plurality of sleeve pieces. An outer curvature of the inner sleeve corresponds to an inner curvature of an inner circumference of the outer sleeve. Inner ridges and outer ridges are respectively formed on an inner surface and an outer surface of each sleeve piece. Each outer ridge of each sleeve piece is in contact with the inner circumference of the outer sleeve. When a post is extended through the inner sleeve, each outer ridge of each sleeve piece presses against the inner circumference of the outer sleeve, and each inner ridge of each sleeve piece presses against the post.

Abstract: A self-adjusting oscillator for a universal-serial-bus (USB) connectivity interface includes at least a voltage controlled oscillator for generating USB synchronous frequency required by a USB connectivity interface and at least a frequency feedback calculating and adjusting unit for capturing synchronous signals, receiving the feedback of the USB synchronous frequency generated by the voltage controlled oscillator and calculating the ratio value of the feedback; the ratio value determines whether the synchronous frequency generated by the voltage controlled oscillator is too fast or too slow such that a frequency adjusting signal is transmitted to the voltage controlled oscillator to form a self-adjusting synchronous oscillator with non-quartz oscillating frequency.
