Abstract: Disclosed is a communication method in a wireless communication system on the basis of a carrier aggregation. The communication method on the basis of a carrier aggregation comprises the steps of: receiving a PDSCH from a base station via a subframe n of a TDD cell; and transmitting, to the base station, a PUCCH including a response to the PDSCH via a subframe n+4 of an FDD cell. Accordingly, an HARQ process may be performed efficiently.

Abstract: Disclosed is device-to-device communication based on a cellular communication network. A method of operating a terminal capable of supporting D2D (device to device) communication based on a cellular communication network may include: determining whether to perform central control D2D communication or distributed control D2D communication; and performing the distributed control D2D communication, or requesting a setting for the central control D2D communication to a base station on the basis of the determination. With the D2D communication based on the cellular communication network, the cellular communication, the central control D2D communication, or the distributed control D2D communication may flexibly and selectively operate in the cellular network.

Abstract: Data transmission and reception is provided by configuring control channels in a wireless communication system using a plurality of carriers. User equipment (UE) may monitor physical downlink control channel (PDCCH) candidates within common search spaces (CSSs) and User Equipment-specific search spaces (USSs). If the UE is configured with cross-carrier scheduling, when two PDCCH candidates originating from a CSS and a USS, respectively, have cyclic redundancy check (CRC) scrambled by the same Radio Network Temporary Identifier (RNTI) and have a common payload size and the same first control channel element (CCE) index, the UE may interpret that only the PDCCH originating from the CSS is transmitted, thereby solving ambiguity of downlink control information (DCI) detection.

Abstract: Provided is a method of compressing an occupancy map of a three-dimensional (3D) point cloud, and more specifically, a method of compressing an occupancy map of a point cloud in which an occupancy map image of a point cloud existing in a 3D space is compressed based on a compression quality or a patch-by-patch inspection method of the occupancy map image so that compression distortion is minimized when reconstructing the compressed occupancy map image so as to remarkably improve the quality of a reconstructed occupancy map image.

Abstract: A reference signal (RS) transmission system to transmit a channel state information (CSI) RS for extraction of CSI to a relay and a macro terminal is disclosed. The base station transmits information on a sub frame containing the CSI RS to the relay or the macro terminal. The macro terminal and the relay receive the CSI RS using the information on the sub frame. The macro terminal and the relay extract the CSI using the CSI RS and transmit the extracted CSI to the base station.

Abstract: Disclosed is a method for signaling control information for coordinated multipoint (CoMP) transmission in a wireless communication system. The control information signaling method for CoMP transmission is performed by a base station and comprises providing, through RRC signaling, a terminal with setup information on each CSI-RS resource of a CoMP measurement group which is set in the terminal; and selectively providing, through DCI, the terminal with control information which indicates mapping of the PDSCH resource element corresponding to terminal and at least either pseudo-same positionality information of CSI-RS or pseudo-same positionality information of DM-RS. Thus, control information signaling for coordinated multipoint transmission can be efficiently performed.

Abstract: Provided are an uplink transmission method and downlink transmission method in a mobile communication network including a relay. In the uplink and downlink transmission methods, frame structures and transmission timings of a backhaul downlink and a backhaul uplink are determined in consideration of at least one of a time for the relay to switch between transmission and reception and a signal transmission time. Accordingly, in a wireless communication system including a relay, it is possible to effectively perform data transmission and reception between the relay and a base station.

Abstract: A type 1 system and a type 2 system are classified according to whether carrier aggregation is used. A shared component carrier is used for both a type 1 terminal and a type 2 terminal, whereas a dedicated component carrier is used only for the type 2 terminal. Also, a type 2 base station transmits broadcast information by using a shared component carrier. In this instance, the broadcast information includes the shared broadcast information used for both the type 1 terminal and the type 2 terminal and the dedicated broadcast information only for the type 2 terminal. Also, the type 2 base station indicates component carriers that are used by the type 2 terminal, by using a semi-static component carrier indicator or a dynamic component carrier indicator.

Abstract: A technology enabling a terminal to receive acknowledgement (ACK)/negative ACK (NACK) information about data transmitted from the terminal is provided. The method includes receiving cyclic shift information for a reference signal from the base station; transmitting, to the base station, the data and a reference signal which is cyclic-shifted using a cyclic shift value, the cyclic shift value being determined based on a dynamic cyclic shift value mapped one-to-one to the cyclic shift information for the reference signal; and receiving, from the base station, the ACK/NACK information about the transmitted data through a radio resource of a downlink channel, the radio resource of the downlink channel being identified based on a modifier mapped one-to-one to the cyclic shift information for the reference signal.

Abstract: A method of transmitting and receiving a control channel in a wireless communication system is provided. A base station allocates a data channel to a radio resource, adds start position information of the data channel into a payload of a control channel, and performs signaling for indication information on the start position information added into the payload of the control channel to a terminal. Accordingly, the legacy system and the enhanced system can efficiently transmit a control channel.
