Abstract: A random access method in a beam division multiple access (BDMA) system including: receiving, by a terminal, a reference signal of at least one beam sector transmitted from an access point (AP) device; estimating, by the terminal, whether the terminal is in a center area of the beam sector provided by the AP device or in the boundary area of the beam sector by using the strength of the reference signal; transmitting, by the terminal, a different preamble to the AP device in accordance with location information of whether the terminal is located in the center area or in the boundary area; and determining, by the AP device, a target beam sector for transmitting information about uplink resources to be used by the terminal, among a plurality of beam sectors on the basis of the received preamble.

Abstract: A receiver of a wireless power transmission system may include a capacitor-and-inductor configured to receive power from a transmitter using a resonance, at least one capacitor configured to connect to an output node of the receiver, and a plurality of switches configured to control current flow within the receiver. The plurality of switches may be controlled so that the capacitor-and-inductor may be disconnected from the at least one capacitor and the output node at preset periods. Current resonating in the capacitor-and-inductor may increase during disconnection between the at least one capacitor and the output node. The plurality of switches may output the increased current to the battery by connecting the capacitor-and-inductor to the capacitor and the output node after the period, connect at least one capacitor and the output node in series after the period, and operate to reduce root mean square (RMS) current within the receiver.

Abstract: A coordinated transmission method based on beam division multiple access and an apparatus performing the same are disclosed. The coordinated transmission method in a beam division multiple access environment, which divides a service target region into a plurality of beam sectors through a plurality of antenna arrays having at least one of a pattern characteristic and a polarization characteristic, includes receiving a coordination request from a user terminal located in the service target region and performing any one among a macro diversity operation, a coordinated silence operation, and a coordinated beamforming operation for the user terminal based on an interference level included in the coordination request.

Abstract: A method and apparatus for improving the performance of voice recognition in a mobile device are provided. The method of recognizing a voice includes: monitoring the usage pattern of a user of a device for inputting a voice; selecting predetermined words from among words stored in the device based on the result of monitoring, and storing the selected words; and recognizing a voice based on an acoustic model and predetermined words. In this way, a voice can be recognized by using prediction of whom the user mainly makes a call to. Also, by automatically modeling the device usage pattern of the user and applying the pattern to vocabulary for voice recognition based on probabilities, the performance of voice recognition, as actually felt by the user, can be enhanced.

Abstract: The present invention relates to a thermoplastic polyurethane composition imparted with crosslinking sites, which comprise a thermoplastic polyurethane containing crosslinking sites incorporated into the molecule of a polyol and/or a chain extender. The thermoplastic polyurethane composition has an easy-to-process viscosity at a processing temperature of about 130° C. or below in a low-temperature foaming process that is performed using an existing EVA crosslinking/foaming system. Thus, the thermoplastic polyurethane composition may be easily mixed with a crosslinking agent, a foaming agent and various additives, and when it is press-molded or injection-molded to provide a crosslinked foam, foam cells are easily formed by the crosslinking sites incorporated into the molecule of the polyol and/or the chain extender.
