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: A method for a base station to configure a channel state information (CSI)-reference signal (RS) is provided. The base station configures a CSI-RS antenna port for a terminal. The base station selects one of at least one port number mapping rule for mapping a port number on the CSI-RS antenna port for the terminal. The base station notifies the terminal of the selected port number mapping rule.

Abstract: A first terminal receives a first Timing Advance (TA) value from a base station and includes a second TA value that is obtained based on the first TA value in a Scheduling Assignment (SA) signal. The first terminal transmits the SA signal to a second terminal at downlink (DL) timing for receiving a downlink signal of the base station in cellular communication. When a length of a Cyclic Prefix (CP) that is set for the D2D communication and a length of a CP that is set for the cellular communication are different, the first terminal transmits data of the D2D communication to the second terminal at first timing that is obtained by applying the second TA value to the DL timing.

Abstract: Disclosed herein are a terminal and an operation method thereof in a MIMO system. The terminal may use a reference signal for channel state measurement from a base station to calculate a first value that is a ratio of a signal transmitted from the base station to noise and a second value that is a ratio of interference from the base station and the noise. Further, the terminal may generate bit information by comparing a ratio of the second value and the first value with a predetermined threshold value and feedback the first value and the bit information to the base station.
