Disclosed are a method and a device for transmitting and receiving an aperiodic reference signal. The method for receiving an aperiodic reference signal comprises: allowing a reference signal receiving device to determine a radio resource area that can be calculated by environmental information from a first reference signal transmission device, and to transmit an aperiodic reference signal to the first reference signal transmission device by including first instruction information which instructs the aperiodic reference signal to be transmitted in the radio resource area; transmitting the aperiodic reference signal by including second instruction information which instructs a second reference signal transmission device, to which a periodic reference signal is to be transmitted in said radio resource area; and receiving the aperiodic reference signal from the first reference signal transmission device in the radio resource area.

The present specification relates to a method and device for allocating uplink power in multiple-TA environments. The method comprises: calculating transmission powers of a PUSCH for subframe m of a first component carrier and subframes k and (k+1) of a second component carrier by using required powers of the PUSCH for the first half and second half of subframe m, which temporally overlaps with the second half of subframe k and the first half of subframe (k+1), available powers of the PUSCH for the first and second components carriers, and required powers of the PUSCH for the second half of subframe K and the first half of subframe (k+1) in a user equipment to which multiple TAs are applied; and setting the transmission power of the PUSCH for subframe m according to the calculated transmission powers and performing uplink transmission to a base station through the subframe m.

Method and device for allocating uplink power in multiple TA environments

The present invention relates to an uplink power control method and apparatus and an uplink signal receiving method and apparatus using the same. According to an embodiment of the present invention, there is provided a method of receiving an uplink signal, the method of including selecting receiving points in a CoMP (Coordinated Multi-Point) system, transmitting CoMP setting information to UE, and receiving uplink transmission from the UE, wherein uplink transmission power used for the uplink transmission is controlled based on an effective path loss calculated by using at least one of path losses between the UE performing the uplink transmission and points in the CoMP system. According to the present invention, when uplink transmission power control is performed in the uplink CoMP system, path losses for a plurality of receiving points are reflected so that power control may be exactly done.

A multimedia contents service system transforms original contents based on selected user preferences chosen by a user or automatic preferences generated from accumulated statistics on user's contents consumption. The system transmits the transformed contents to the user and provides services which perform rendering or storing according to user preferences. Therefore, the system provides contents transformed according to user's interests to thereby increase user's convenience (universal multimedia access) and satisfy a variety of user's demands.

System, method and storage medium for providing a multimedia contents service based on user's preferences

An apparatus and method for reproducing data from a recording medium includes a reproducing unit reproducing data from a medium, each data including an identification number corresponding to said each data; a decoder including an internal memory, storing the data from the reproducing unit in the internal memory, decoding the data stored in the internal memory, and generating a first signal indicating that the internal memory is full; and a controller receiving the first signal from the decoder, generating a jump signal to the reproducing unit based on the first signal to move a reader of the reproducing unit from the current position to a predetermined prior position on the medium, generating a second signal to the decoder for instructing the decoder to stop storing the data from the reproducing unit, and generating a third signal when the reader reaches the current position on the disc from the predetermined initial position. The third signal instructs the decoder to resume its storing process in the internal memory of the decoder.
