Method for transmitting control information in a wireless communication system, and device therefor

摘要

The present invention discloses a method for a terminal to transmit control information in a wireless communication system. The method includes encoding a plurality of pieces of control information and transmitting the plurality of encoded control information and data information through a data channel. During the encoding of the plurality of control information, a channel quality indicator (CQI) and a precoding matrix index (PMI) for an entire frequency band are encoded jointly or separately, and each piece of the plurality of pieces of encoded control information and the data information is mapped into a resource block of the data channel, and is then transmitted.

1. A method of transmitting information by a user equipment (UE) in a wireless communication system, the method comprising:
coding a plurality of control information including a precoding matrix index (PMI) for a whole frequency band, ACK/NACK information and a rank indicator (RI); and transmitting a plurality of the coded control information and a data information mapped to a data channel on a subframe including a plurality of symbols, wherein the PMI for the whole frequency band and the rank indicator (RI) are separately coded, wherein the RI is mapped to a 2nd, 6th, 9th and 13th symbol in the subframe, the ACK/NACK information is mapped to a 3rd, 5th, 9th and 11th symbol and the data information is mapped to 1st and 14th symbol, wherein the separately coded PMI, the ACK/NACK information and the data information are mapped to at least subcarriers having a same frequency location as specific subcarriers to which the RI is mapped, and wherein the separately coded PMI is mapped to only a 7th and 8th symbol in the subframe.
