METHOD AND DEVICE FOR TRANSMITTING UPLINK CONTROL INFORMATION IN WIRELESS COMMUNICATION SYSTEM

摘要

Disclosed are a method and a device for transmitting uplink control information (UCI) by a terminal in a wireless communication system. The UCI transmission method comprises the steps of: generating an encoding information bit stream by performing channel coding for a UCI bit stream; generating complex modulation symbols by performing modulation for the generated encoding information bit stream; spreading the complex modulation symbols in block-wise on the basis of an orthogonal sequence; and transmitting the spread complex modulation symbols to a base station. The encoding information bit stream is generated by a channel coding for circularly repeating the UCI bit stream.

1. A method for transmitting hybrid automatic repeat request (HARQ) acknowledgement (ACK) information on a physical uplink control channel (PUCCH), by a user equipment (UE), in a wireless communication system, the method comprising:
obtaining encoded information bits by circular repetition of a sequence, which is generated by encoding HARQ-ACK information bits for a plurality of serving cells, if the number of the HARQ-ACK information bits is less than a specific value M; generating modulation symbols by modulating the encoded information bits; dividing the generated modulation symbols into a first slot and a second slot; discrete Fourier transform (DFT) precoding the divided modulation symbols; and transmitting the DFT precoded modulation symbols to a base station.
