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.

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: The present invention provides a method of performing a position measurement on the basis of a signal from a global navigation satellite system (GNSS). The method includes: receiving initial position information; estimating an initial value of a multipath error through a measurement of the GNSS signal on the basis of the received initial position information; estimating a multipath error from the initial value of the multipath error on the basis of a change in the measurement; removing the estimated multipath error from the measurement of the GNSS signal; and performing the position measurement on the basis of the GNSS measurement from which the multipath error is removed.

Abstract: The present invention relates to a multi-input and multi-output communication method in a large-scale antenna system. An MIMO transmission method according to the present invention includes: obtaining statistical channel information on at least one terminal, dividing terminals into a plurality of classes and a plurality of groups based on the statistical channel information, wherein the groups depend on the classes; determining a group beam-forming matrix for each of the divided groups; performing a group beamforming transmission by group based on the group beam-forming matrix to obtain instantaneous channel information; and scheduling terminals based on the instantaneous channel information. Thus, it is possible to decrease the complexity in a scheduling and precoding calculation without an increase in the amount of wireless resources that are required for providing feedback for a reference signal and channel status information.

Abstract: Disclosed is a method of sensing illegal flight of a low-flying drone. Here, the method of sensing illegal flight includes: changing a direction of a beam on the basis of a preset period; and detecting an object by using the beam changed on the basis of the preset period. Here, the direction of the beam is changed on the basis of a first direction and a second direction. The first direction is changed on the basis of conversion of a center frequency, and the second direction is changed on the basis of a phase and a particular value.

Abstract: A dynamic channel assignment method includes receiving, at a ground control station (GCS), assignment of a first communication channel set from a spectrum authority before takeoff of the unmanned aircraft; receiving, at the GCS, assignment of a second communication channel set when the unmanned aircraft is to move from a first area using the first communication channel set to a second area using the second communication channel set due to a flight plan of the unmanned aircraft after takeoff of the unmanned aircraft; and after the unmanned aircraft enters the second area, maintaining, at the GCS, the first communication channel set when the unmanned aircraft reenters the first area due to the flight plan, and returning, at the GCS, the first communication channel set to the spectrum authority when the unmanned aircraft does not reenter the first area due to the flight plan.
