Abstract:
A method and apparatus for transmitting a synchronization signal in a talk-around direct communication network is provided. The method includes: determining one of a plurality of second windows included in a first window as a synchronization reception window; selecting one of a plurality of synchronization slots included in the second windows as a first synchronization slot; transmitting a first synchronization signal through the first synchronization slot included in the second windows, excluding the synchronization reception window; detecting a second synchronization signal transmitted from other terminals using the first synchronization slot included in the synchronization reception window; and determining that a collision from amongst the synchronization signals has occurred based on the detection result.
Abstract:
Provided are a display apparatus and method based on an SSPB. The display apparatus includes a panel configured to play a 3-D image, a parallax barrier configured to include liquid crystals placed in the front of the panel and configured to transmit or block light emitted from the panel and pairs of transparent electrodes obliquely arranged to cross each other in a symmetric form in the front and rear of the liquid crystals based on the liquid crystals, and a driving unit configured to apply driving voltages to the parallax barrier. The parallax barrier can transmit or block a specific part of the played 3-D image through the panel in response to the applied driving voltages.
Abstract:
An operation method of a terminal in a communication system includes transmitting a measurement report message of each of one or more neighbor base stations to a source base station, the one or more neighbor base stations satisfying a handover (HO) preparation event; receiving, from the source base station, a conditional HO command message of each of at least one of neighbor base stations among the one or more neighbor base stations; determining a target base station based on priority of a neighbor base station which satisfies a HO execution event among the at least one of neighbor base stations; and performing a handover with the target base station.
Abstract:
Disclosed are a method and an apparatus for providing low-latency services in a communication system. A downlink communication method may comprise receiving downlink control information (DCI) including resource allocation information from a base station through a control channel of a subframe receiving downlink data from the base station through a data channel of a subframe #n+k indicated by the resource allocation information included in the DCI; and transmitting a first hybrid automatic repeat request (HARM) response for the downlink data to the base station through a control channel of a subframe #n+k+l. Thus, the performance of the communication system can be improved.
Abstract:
Disclosed is a mobile communication network system and a network configuring method. The communication network system includes: a common control access network; at least one access network slice added according to a service type requested by a device; a common control core network; and at least one core network slice added according to a service type requested by the device. The access network slice and the core network slice are determined by the service type requested by the device.
Abstract:

Abstract:
A method of providing cooperative communication to a terminal through a plurality of base stations is provided. A plurality of base stations each transmit a midamble to a terminal, and the terminal measures a channel through a received midamble. The terminal transmits information about the measured channel to at least one of the plurality of base stations.

A data relay method includes receiving a relay request from a BS, and when the relay request is accepted, relaying data between the BS and at least one external terminal, or the data relay method includes determining relaying between a first terminal among a plurality of terminals, and other remaining terminals excluding the first terminal among the plurality of terminals, and relaying data between the first terminal and the other remaining terminals.
Abstract:
A display panel based on a segmented parallax barrier according to the present invention includes the segmented parallax barrier disposed in a front or back of an image panel and configured to block a specific part of an image displayed through the image panel and wherein the segmented parallax barrier is configured to connect fine transparent electrodes belonging to an identical group through a transparent electrode, from among fine transparent electrodes grouped in specific patterns, so that voltage is supplied to the fine transparent electrodes without an additional feed line assigned to each fine transparent electrode. Accordingly, the production cost of a TN-LCD panel based on a segmented parallax barrier can be reduced, and a TN-LCD panel having excellent barrier pattern characteristics can be easily manufactured.
Abstract:
A signaling method for a terminal that performs direct communication between terminals terminal is disclosed. A transmitting terminal transmits a link establishment request message for establishing a link to a receiving terminal, and the receiving terminal transmits a link establishment response message responding to this message to the transmitting terminal. The link establishment request message includes a field indicating a flow to use if the receiving terminal acquires a token.
