Abstract

An embodiment of the invention provides a method for transmitting control information, a user device and a base station. The method for transmitting control information comprises of the steps of obtaining resource index of a physical uplink control channel (PUCCH), wherein the PUCCH is sued for transmitting uplink control information (UCI); obtaining sequence index of an orthogonal sequence of the PUCCH according to the resource index and obtaining the orthogonal sequence according to the sequence index; obtaining cyclic shift of a reference signal of the PUCCH according to the sequence index; and transmitting the UCI to the base station on the PUCCH according to the orthogonal sequence and the cyclic shift. The cyclic shift of the reference signal of the PUCCH for transmitting the UCI is obtained according to the sequence index, and the UCI is transmitted on the PUCCH according to the cyclic shift and according orthogonal sequence, and the UCI transmission performance can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of wireless communication, and more specifically, to a method for transmitting control information, a user equipment, and a base station. Background technique [0002] LTE-A (Long Term Evolution-Advanced, Advanced Long Term Evolution) is a further evolution and enhanced system of the 3GPP LTE system. In the LTE-A system, in order to meet the peak data rate requirements of the International Telecommunication Union for the fourth-generation communication technology, the carrier aggregation (Carrier Aggregation, CA) technology, also known as the spectrum aggregation (Spectrum Aggregation) technology or the bandwidth extension (Bandwidth Extension) technology is introduced. )technology. In carrier aggregation, the frequency spectrum of two or more component carriers (Component Carrier) is aggregated together to obtain a wider transmission bandwidth. The spectrum of each component carrier can be ...
