Abstract
The present invention provides a method and apparatus for transmitting uplink control information (UCI) with user equipment in a wireless communication system. The user equipment performs channel coding on information bits of UCI to generate encoded information bits; modulates the generated encoded information bits to generate complex modulation symbols; spreads the complex modulation symbols blockwise into a plurality of single carrier frequency division multiple access (SC-FDMA) symbols on the basis of an orthogonal sequence; and transmits the spread complex modulation symbols to a base station.
Claims15
A method for transmitting uplink control information (UCI) by a user equipment on a physical uplink control channel (PUCCH) in a wireless communication system, the method comprising:
- performing channel coding on information bits of the UCI to generate encoded information bits, wherein the information bits of the UCI include hybrid automatic repeat request (HARQ)-ACK(acknowledgement) information bits for serving cells, and wherein a number of information bits of the UCI is determined based on a number of the serving cells and a number of codewords for each of the serving cells, which is based on a transmission mode of each of the serving cells;
- modulating the encoded information bits to generate complex modulation symbols;
- block-wise spreading the complex modulation symbols on the basis of an orthogonal sequence;
- and
- transmitting the spread complex modulation symbols to a base station.
A user equipment in a wireless communication system, the user equipment comprising:
- a radio frequency (RF) unit for transmitting or receiving a radio signal;
- and
- a processor connected to the RF unit, and configured for:
- performing channel coding on information bits of the UCI to generate encoded information bits, wherein the information bits of the UCI include hybrid automatic repeat request (HARQ)-ACK(acknowledgement) information bits for serving cells, and wherein a number of information bits of the UCI is determined based on a number of the serving cells and a number of codewords for each of the serving cells, which is based on a transmission mode of each of the serving cells;
- modulating the encoded information bits to generate complex modulation symbols;
- and
- block-wise spreading the complex modulation symbols on the basis of an orthogonal sequence.
