Method and apparatus for transmitting control information in wireless communication system

摘要

The present invention relates to a wireless communication system. More specifically, the present invention relates to a method for transmitting control information through a PUCCH in a wireless communication system and an apparatus thereof, comprising the steps of: spreading modulation symbol sets to first slot, by using a first code; spreading modulation symbol sets to second slot, by using a second code, wherein the length of the second code is varied according to the number of SC-FDMA symbols for PUCCH transmission.

1. A method for, at a user equipment (UE), transmitting control information through a physical uplink control channel (PUCCH) in a wireless communication system, the method comprising:
joint-coding a plurality of control information to generate N1 modulation symbol sequence, wherein N1 is twice of a number of subcarriers in one resource block (RB); dividing the N1 modulation symbol sequence such that a first set of consecutive N1/2 modulation symbols of the N1 modulation symbols corresponds to a first slot of the PUCCH and a second set of consecutive N1/2 modulation symbols of the N1 modulation symbols corresponds to a second slot of the PUCCH; transmitting a first set of discrete-Fourier-transformed signals through a first set of single carrier frequency division multiple access (SC-FDMA) symbols in a first slot, each of the first set of discrete-Fourier-transformed signals including the first set of consecutive N1/2 modulation symbols; and transmitting a second set of discrete-Fourier-transformed signals through a second set of SC-FDMA symbols in a second slot, each of the first set of discrete-Fourier-transformed signals including the second set of consecutive N1/2 modulation symbols, wherein the first set of SC-FDMA symbols is covered by a first code, and the second set of SC-FDMA symbols is covered by a second code, and wherein the length of the first code is fixed irrespective of the number of the SC-FDMA symbols for the PUCCH transmission, and the length of the second code is varied according to the number of SC-FDMA symbols for PUCCH transmission.
