Abstract

A method for transmitting uplink control information and an apparatus therefor are disclosed. In a method for transmitting uplink control information using a physical uplink shared channel (PUSCH) in a wireless communication system, the method is performed by a terminal and includes receiving downlink control information including an accumulated number of physical downlink shared channels (PDSCH) transmissions associated with a cell group configured for the terminal, coding the uplink control information using the accumulated number of PDSCH transmissions, and transmitting the coded uplink control information using the PUSCH.

Description

technical field [0001] The present invention relates to a wireless communication system, and more particularly, to a method and device for sending uplink control information. Background technique [0002] Recently, various devices requiring machine-to-machine (M2M) communication and high data transfer rates, such as smart phones or tablet personal computers (PCs), have emerged and are widely used. This rapidly increases the amount of data that needs to be processed in the cellular network. In order to meet such rapidly increasing data throughput, recently, carrier aggregation (CA) technology that effectively uses more frequency bands, cognitive radio technology, multiple antenna (MIMO) technology for increasing data capacity in limited frequencies, multiple Base station cooperation technology and the like have received attention. Furthermore, the communication environment has evolved such that the density of accessible nodes increases in the vicinity of a user equipment (U...
