Abstract

Provided in one disclosure of the present specification provides a method for transmitting a physical uplink control channel (PUCCH) including uplink control information (UCI), when more than five cells are used by a user equipment (UE) according to carrier aggregation. The method may comprise the steps of: encoding UCI of K bits, which exceeds 20 bits, and outputting encoded bits of N bits; and mapping on resource elements (RE) in an uplink subframe, without applying an orthogonal cover code (OCC) to the encoded N bits, wherein the uplink subframe may include two symbols, and wherein each symbol may include 12 subcarriers on a frequency axis and six or seven symbols on a time axis. The mapping step may be carried out according to a symbol index and from among symbols remaining after excluding symbols for a demodulation reference signal (DMRS) and a subcarrier index.

Description

technical field [0001] The present invention relates to mobile communications. Background technique [0002] 3GPP (3rd Generation Partnership Project) LTE (Long Term Evolution), which is an evolution of UTMS (Universal Mobile Telecommunications System), was introduced in 3GPP Release-8. In 3GPP LTE, OFDMA (Orthogonal Frequency Division Multiple Access) is used for downlink, and SC-FDMA (Single Carrier Frequency Division Multiple Access) is used for uplink. 3GPP LTE employs MIMO (Multiple Input Multiple Output) with up to four antennas. Recently, discussion of 3GPP LTE-A (LTE-Advanced), which is an evolution of 3GPP LTE, is underway. [0003] As proposed in 3GPP TS 36.211V10.4.0, physical channels in 3GPP LTE can be classified into data channels such as PDSCH (Physical Downlink Shared Channel) and PUSCH (Physical Uplink Shared Channel), and channels such as Control channels of PDCCH (Physical Downlink Control Channel), PCFICH (Physical Control Format Indicator Channel), PH...
