Abstract

A method for transmitting uplink control information in a wireless communication system according to an embodiment of the present invention, is performed by a terminal, may comprise the steps of: determining the number of coded symbols according to the payload size of uplink control information to be transmitted; and mapping the uplink control information to an uplink resource according to the determined number of the coded symbols, wherein the number of the coded symbols is determined by using a parameter selected according to the payload size of the uplink control information to be transmitted.

Description

technical field [0001] The present invention relates to a wireless communication system, and more particularly, to a method and apparatus for transmitting uplink control information. Background technique [0002] Various devices and technologies including smartphones, tablet PCs, and the like that require M2M (Machine-to-Machine) communication and high data throughput are emerging and spreading. Consequently, the amount of data that needs to be processed in cellular networks is growing rapidly. In order to meet rapidly increasing data processing demands, carrier aggregation technology for effectively using more frequency bands, cognitive radio technology, multi-antenna technology for increasing data capacity transmitted in a limited frequency, multi-base station cooperation technology, etc. etc are under development. Furthermore, the communication environment is evolving in such a way that the density of nodes to which proximate devices can access increases. A node corres...
