Abstract: The method for transmitting control information in a mobile communication system includes: determining a control channel resource for transmitting control information by means of the data channel region; and transmitting the control information using the determined control channel resource. A capacity for control information, which increases for multiple user multiple-input multiple-out (MIMOs) in a heterogeneous network environment, for heterogeneous network interference control using carrier aggregation, for frequent use of a multicast-broadcast single frequency network (MBSFN) subframe, and for a CoMP transmission control, may be satisfied. Further, an adaptive resource allocation based on a requested capacity for control information may be enabled, and the efficient utilization of resources may also be enabled.

Abstract: The present invention relates to a method for transmitting uplink control information in a mobile communication system; and, more particularly, to a method for effectively forming uplink control information transmitted through a downlink from a base station to a terminal in a mobile communication system for providing a packet service and transmitting the uplink control information with minimum radio resources occupied. The method includes the steps of generating uplink control information; allocating the uplink control information to a downlink-shared radio resource for packet data transmission based on downlink scheduling information; and transmitting the radio resource to a terminal. The present invention is applied to a mobile communication system.

Abstract: A signal transmitting method according to an exemplary embodiment of the present invention includes channel-coding broadcasting channel information by using a first scrambling code in a first frame within a broadcasting channel information updating period including a plurality of frames, and channel-coding the broadcasting channel information by using a second scrambling code in a second frame within the broadcasting channel information updating period. The second scrambling code is different from the first scrambling code.

Abstract: A positioning method using images and radio waves may include: estimating a distance and an angle from the positioning reference node to a positioning target terminal; identifying an obstacle or reflective object in a vicinity of the positioning target terminal or on a path between the positioning target terminal and the positioning reference node by using image information on the positioning target terminal at a position estimated by the distance and the angle; estimating an incident angle or a reflection angle of a radio wave signal reflected by the reflective object identified based on the image information; and estimating a position of the positioning target terminal based on the reflection angle and the distance.

Abstract: Disclosed is a wireless communication system using multiple transmission and reception points. In a wireless communication system having a first transmission and reception point and at least one second transmission and reception point belonging to the same cell, the first transmission and reception point has a wider transmission area than the at least one second transmission and reception point, and the first transmission and reception point and the at least one second transmission and reception point generate downlink transmission signals by using the same physical layer cell ID or virtual cell IDs allocated to each terminal, and then the terminals generate uplink transmission signals by using the allocated virtual cell IDs.

Abstract: When a plurality of terminals share the same resources in a wireless communication system, and when control information such as acknowledgement/negative acknowledgement (ACK/NAK) information or scheduling information is transmitted, a method of efficiently performing code division multiplexing (CDM) is required to distinguish the plurality of terminals. In particular, it is necessary to develop a method by which a code sequence of CDM can be selected and used according to each cell condition. Provided is a method of forming a signal in a wireless communication system in which a plurality of terminals commonly share frequency and time resources. The method includes the operations of receiving condition information in a cell; selecting one of a plurality of time domain orthogonal sequences having different lengths, according to the condition information; and allocating the selected time domain orthogonal sequence to a control signal symbol block.
