A movable electronic apparatus is provided. The movable electronic apparatus includes: a display; a processor configured to: identify that the electronic apparatus is located in a first space among a plurality of spaces, display an image of a first content group including at least one piece of first content corresponding to the first space among a plurality of pieces of content on the display, identify that the electronic apparatus moves from the first space to a second space, and display an image of a second content group including at least one piece of second content corresponding to the identified second space on the display.

Identification of a room among plural rooms where a movable electronic apparatus is located and/or moving to and display of content group corresponding to the identified room

An electronic device including a plurality of microphones and a processor is provided. The electronic device includes a plurality of microphones disposed at different positions in the electronic device, a processor configured to collect input signals input to each of the microphones, acquire direction of arrival (DOA) information corresponding to each of the microphones from the input signals, calculate generation directions of the input signals using the DOA information, adjust a weight of an input signal for each of the microphones, based on the generation directions of the input signals, and generate an output signal for each of the microphones by reflecting the weight adjusted for each of the microphones, and a speaker configured to output an output signal for each of the microphones.

Embodiments of the present invention relate to a wireless communication system, and more particularly, to a technology for allocating a Channel State Information-Reference Signal (CSI-RS) in a wireless communication system. Embodiments of the present invention provides an apparatus and method for allocating CSI-RSs to resource areas, in which, under the condition of a subframe in which the CP is an extended CP, and the duplex scheme is TDD, if CSI-RSs for maximum 8 antenna ports are allocated, the CSI-RSs are allocated to the 8th and 9th symbols (symbol No. l=7 and 8), wherein each CSI-RS for every two antenna ports is allocated to the same RE while being discriminated from each other by an orthogonal code and neighbor CSI-RS allocated REs in the frequency axis are spaced by an interval of three REs.

Apparatus and method for allocating channel state information-reference signal in wireless communication system

A base station includes: an area information generation unit which generates information for a determined second area by determining an additional assignment of the second area different from a first area to a component carrier (CC) of the first area having a bandwidth smaller than a bandwidth of a maximum assignable CC; a mapping control unit which controls an assignment of a reference signal to a frequency band including the first and second areas by generating the reference signal for channel estimation in the first and second areas; a signal generation unit which generates the information for the second area and the reference signal as a wireless signal; and a transmission unit for transmitting the generated wireless signal and is characterized by transmitting data to a user terminal and receiving the data from the user terminal by assigning the resources to the first and second areas.

Method and apparatus for transmitting and receiving extension information of component carrier in wireless communication system

The present invention relates to an apparatus and a method for composing and transmitting/receiving a reference signal in a wireless communication system that uses a plurality of component carriers (CC). In a wireless communication system using a plurality of component carriers, the present invention can reduce an increase in cubic metric (CM) and peak to average power ratio (PAPR) which occur in the course of composing and transmitting/receiving the same reference signal for each component carrier, by composing and transceiving a distinctive reference signal for each component carrier.

Apparatus and method for generating and transceiving reference signal in wireless communication system using plural component carriers

A base station comprises: an area information generation unit which generates information for a determined second area by determining an additional assignment of the second area different from a first area to a component carrier (CC) of the first area having a bandwidth smaller than a bandwidth of a maximum assignable CC; a mapping control unit which controls an assignment of a reference signal to a frequency band including the first and second area by generating the reference signal for channel estimation in the first and second areas; a signal generation unit which generates the information for the second area and the reference signal as a wireless signal; and a transmission unit for transmitting the generated wireless signal and is characterized by transmitting data to a user terminal and receiving the data from the user terminal by assigning the resources to the first and second areas.

Disclosed are apparatuses and methods for transmitting and receiving control information, such as downlink assignment and uplink grant, to each CC through a DCI format of a PDCCH in a wireless communication system using a plurality of CCs. Exemplary embodiments include configuration and transmission of a CC indicator for the DCI format, in order to identify a CC to which the control information transferred by each DCI format corresponds from among the CCs.
