Abstract

A method and apparatus for transmitting and receiving control information in an SC-FDMA system are provided. Different orthogonal codes are generated for different slots each including a plurality of SC-FDMA symbols in a subframe. A control channel signal is generated by multiplying control symbols carrying control information by a sequence allocated for CDM of the control information. The control channel signal is multiplied by chips of the orthogonal codes on an SC-FDMA symbol basis and transmitted in the SC-FDMA symbols.

Description

technical field [0001] The present invention generally relates to mobile communication systems, and more particularly, to a method for transmitting and receiving control information randomizing inter-cell interference caused by uplink (UL) transmissions in a next-generation multi-cell mobile communication system and device. Background technique [0002] In the field of mobile communication technology, Orthogonal Frequency Division Multiple Access (OFDMA) or Single Carrier-Frequency Division Multiple Access (SC-FDMA) has recently been studied for use in radio channels. High-speed transmission. The 3rd Generation Partnership Project (3GPP), an asynchronous cellular mobile communication standardization organization, is working on the Long Term Evolution (LTE) of the next generation mobile communication system related to the multiple access scheme. [0003] According to data transmission or non-data transmission, the LTE system uses different transport formats (Transport Forma...
