摘要:
A method of transmitting data using hybrid automatic repeat request (HARQ) is provided. The method includes transmitting an initial data, receiving a retransmission request for the initial data, generating a retransmission data by shifting the phase of the initial data on signal constellation and transmitting the retransmission data. Inter-cell interference or intra-cell interference can be mitigated.

A method of selecting a modulation and coding scheme (MCS) index in a wireless communication system is disclosed. More specifically, the method includes measuring a frequency selectivity of a receiving channel, selecting a MCS index having a coding rate below a prescribed coding rate threshold value if the measured frequency selectivity is greater than or equal to a specified frequency selectivity threshold, and selecting the MCS index having the coding rate above or equal to the prescribed coding rate threshold value if the measured frequency selectivity is less than the specified frequency selectivity threshold.

A transmitter for reducing time selectivity and/or frequency selectivity in a wireless communication system includes a plurality of transmit antennas, a phase shifter which is disposed for each transmit antenna and is configured to shift a phase of data transmitted through the transmit antenna by a phase shift value, and a channel selectivity processor configured to obtain the phase shift value by using a channel phase value fed back from a receiver.
摘要:
A method for transmitting a voice over Internet protocol (VoIP) packet includes allocating a radio resource for VoIP packet transmission to a user, transitioning a VoIP service from a talk period, in which the VoIP packet is transmitted using the radio resource, to a silence period in which the VoIP packet is not transmitted, releasing the radio resource during the silence period, and transitioning the VoIP service to the talk period by reallocating the radio resource. Limited radio resources can be further effectively used.

A liquid crystal display has touch a sensing layer disposed above an image forming part. The liquid crystal display includes: a lower panel including a first substrate and a plurality of gate lines and a plurality of data lines formed on the first substrate; an upper panel including a second substrate, a first sensing unit formed on the second substrate, a source voltage line, a bias voltage line, and first and second sensing data lines that are respectively formed on opposed longitudinal sides of one of the source voltage line or the bias voltage line; and a liquid crystal layer interposed between the lower panel and the upper panel, wherein the first sensing unit includes a switching transistor electrically connected to one of the first sensing data line and the second sensing data line and a sensing transistor electrically connected to the source voltage line and the bias voltage line, the source voltage line and the sensing data line extend longitudinally in the same direction as a plurality of data lines, and the source voltage line or the bias voltage line overlaps directly above a corresponding data line among a plurality of data lines.
摘要:
The present invention discloses a molded article with an antimicrobial property, and a manufacturing method thereof. The molded article can prevent contact of bacteria or viruses by combining the Kimchi lactic acid bacteria culture fluid having antibacterial and antivirus effects with a raw material. The molded article needing the antimicrobial effect is provided with the antimicrobial property, by incorporating the Kimchi lactic acid bacteria culture fluid with a wide antibacterial spectrum singly or in combination with nano metal particles. The Kimchi lactic acid bacteria culture fluid is combined in the molding step of the article, for reducing the manufacturing time and simplifying the manufacturing process.

A method and an apparatus for transmitting control information for multicast broadcast service (MBS) is provided. The method includes configuring one cell specific control channel for carrying cell specific control information; configuring at least one non-cell specific control channel for carrying non-cell specific control information; and transmitting the cell specific control channel and the non-cell specific control channel to a mobile station.
摘要:
A method of transmitting an interference information signal in a wireless communication system is provided. The method includes receiving a neighbor sounding signal from a mobile station (MS) in a neighbor cell, obtaining an interference information signal based on the neighbor sounding signal and transmitting the interference information signal to a neighbor base station (BS), the neighbor BS which is a BS in the neighbor cell.
