    摘要: A base station (BS) for a mobile communication system is provided. As for a user equipment (UE), the BS is a primary BS and connects to a secondary BS. The primary BS calculates the time synchronization error between the primary BS and the UE, and the time synchronization error between the secondary BS and the UE. These time synchronization errors are associated with the subcarrier spacings (SCSs) of the primary and secondary BSs, respectively. According to the calculated time synchronization errors, the primary BS transmits a synchronization indication message to instruct the UE to receive the reference time information of one of the primary and secondary BSs.

    摘要: In a wireless communication core network, an Application Function (AF) make an analysis request for a mobility analytics report of a UE, which includes first UE mobility information of the UE. In the wireless communication core network, a Network Data Analysis Function (NWDAF) obtains an identity of an Access and Mobility Management
    Function (AMF) serving the UE from a Unified Data Management (UDM), on its own or via a Network Exposure Function (NEF), based on the request. Then, the NWDAF obtains second UE mobility information of the UE from the AMF according to the identity of the AMF, and generates and transmits the mobility analytics report to the AF according to the first and second UE mobility information.

    摘要: A virtuality-reality overlapping method is provided. A point cloud map related to a real scene is constructed. Respective outline border vertexes of a plurality of objects are located by using 3D object detection. According to the outline border vertexes of the objects, the point cloud coordinates of the final candidate outline border vertexes are located according to the screening result of a plurality of projected key frames. Then, the point cloud map is projected to the real scene for overlapping a virtual content with the real scene.

    摘要: A feature determination apparatus and method adapted to multiple object sizes are provided. The apparatus individually supplies each of the object images to a convolution neural network having several convolution layers to generate multiple feature maps corresponding to each object image. The apparatus calculates a feature amount of each feature image of each object image. The apparatus determines an invalid layer start number of each object image according to a preset threshold and the feature amount corresponding to each object image. The apparatus determines a feature map extraction recommendation for each of a plurality of object sizes according to a size of each object image and the invalid layer start number of each object image.

    摘要: A base station (BS) and data transmission method thereof for mobile communication system thereof are provided. The BS transmits an ultra-reliable transmission parameter of a user equipment (UE) to a core network to make a user plane function (UPF) of the core network establish a first protocol data unit (PDU) session with the UE via the BS. The BS selects a secondary BS and transmits UE information to the secondary BS over a communication interface. The BS transmits a BS selection message to the UE to make the UE connect to the secondary BS. The BS transmits the BS selection message to the core network to make another UPF of the core network establish a second PDU session with the UE via the secondary BS.

    摘要: A user equipment (UE) and a base station (BS) are provided. The UE transmits a specific preamble on a random access channel and transmits an uplink data signal and a demodulation reference signal (DMRS) on an uplink transmission radio resource so that the BS receives the uplink data signal and the DMRS according to the specific preamble after receiving the specific preamble. The BS transmits a downlink data signal on a downlink transmission radio resource according to the specific preamble so the UE receives the downlink data signal on the downlink transmission radio resource according to the specific preamble.

    摘要: A film pressure sensing device and a pressure sensing system for an exercise equipment are provided. The pressure sensing system includes an electronic device and at least one film pressure sensing device. Each film pressure sensing device includes a film sensing module and a processing module. The film sensing module includes a plurality of film pressure sensing elements, each of which senses pressure on a specific position of the exercise equipment to generate a pressure sensing signal. The processing module connects to the film pressure sensing elements via a plurality of conducting wires to receive the pressure sensing signals. The processing module generates a sensing data according to the pressure sensing signals, and transmits the sensing data to the electronic device. The film sensing module is flexible to be tightly disposed on a component of the exercise equipment, where the component corresponds to a part of a user's body.
