    Abstract: A stepping motor for optical pick-up devices is disclosed. In the stepping motor, a stator, having a coil and a yoke, is fixed to a first support plate. A rotating shaft is rotated by the coil of the stator, with a first end of the shaft being inserted into the stator and a second end being exposed outside the stator and being externally threaded to form a lead screw. The first and second ends are each domed. A first holder, having a trapezoidal dent, rotatably holds the domed first end of the shaft within the trapezoidal dent while being brought into point contact with the domed first end. A second holder, having a trapezoidal dent, rotatably holds the domed second end of the shaft within the trapezoidal dent while being brought into point contact with the domed second end. The second holder is supported by a second support plate while being normally and elastically biased by a spring means in an axial direction of the rotating shaft, thus elastically supporting the shaft in the axial direction. Due to such a simple support structure for the rotating shaft, the stepping motor has a reduced number of elements and is easily produced through a simple process while accomplishing improved operational reliability and improved productivity and reducing the operational noises.

    Abstract: In a relay based wireless communication system, a method for transmitting an uplink backhaul sub-frame of a relay node includes obtaining scheduling information for an uplink backhaul sub-frame through a downlink backhaul control channel from a base station, and performing a rate matching and mapping of data by regarding at least one predefined symbol as a blank symbol. The predefined symbol is located at a front part or a rear part of the scheduled uplink backhaul sub-frame. The transmitting method further includes performing a multiplexing of the uplink backhaul sub-frame, and transmitting the multiplexed uplink backhaul sub-frame. This method can eliminate an overlap of transmission and reception timing in a relay node due to an RF transmission/reception switching time delay. Also, the method can make better use of wireless backhaul resources and minimize an influence on conventional systems by offering the compatibility with conventional uplink and downlink sub-frame structures.

    Abstract: A base station in a downlink of a wireless communication system requires downlink channel status information of terminals to transmit link-adaptive transmission to the terminals. This channel status information is generated as a terminal receives a reference signal to be transmitted via the downlink, and fed back to the base station through a control channel of the uplink. Therefore, an increase in the transmission cycle of the reference signal and the feedback cycle of the channel status information may increase a difference between the channel status having been fed back from a terminal to the base station and the channel status at the point when data is actually transmitted to the terminal, thereby causing inefficient link-adaptive transmission and deteriorating the system performance. The present invention thus provides a method and apparatus for designing an uplink periodic feedback structure for reducing the channel status difference in case a reference signal for the estimation of a downlink channel status is transmitted over a prolonged cycle, and distributing a feedback overhead of terminals in terms of the system.

    Abstract: Coordinated multipoint communication is a technology for improving cell-edge performance for users in a cell-type mobile communication system. In order to enable a coordinated multipoint transmission/reception operation, a user equipment report of a local environment is required to select both coordinated communication modes and communication partners in evolved Node B (eNB) base stations. According to the present invention, a method is described for feeding back information from User Equipment (UE) to a serving base station to enable a coordinated multi-point transmission/reception operation. The information reported through the feedback is classified into two categories corresponding to received signal intensity information and received signal timing information. The UE may select one or both types of information from between the categories to provide feedback. In embodiments of the present invention, various overhead-reducing reporting formats are described.

    Abstract: In a wireless communication system a control channel is required in order to use limited resources effectively. However, the control channel resource is part of the system overhead, and thus reduces the data channel resource used for data transmission. In the long term evolution (LTE) system based on OFDM, one sub frame the consists of fourteen OFDM symbols wherein a maximum of three OFDM symbols are used for the control channel resource and remaining eleven OFDM symbols are used for the data channel resource. Therefore, the quantity of energy that can be transmitted for the control channel resource is extremely limited compared to the data channel resource. For this reason, the coverage of the control channel becomes less than that &; of the data channel, and even if a user can successfully receive the data channel, reception failure of a control channel sometimes˜results in failure of data recovery. In the present invention, in order to expand the coverage of the control channel to at least the coverage of the data channel, the time resource of the transmission resource wherein the control channel is transmitted is expanded and allocated for sending and receiving the control channel. By way of methods for extending the time resource are provided a method wherein a plurality of sub frames are used to transmit one control channel, and a method wherein a part of a data channel is used for the control channel.
