Abstract

Embodiments of the present invention provide a method for sending control information and a communication device. The embodiments of the present invention can solve the problem that the user equipment and the base station equipment have inconsistent understandings of the total number of original information bits of the HARQ-ACK of multiple downlink carriers.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular, to a method for sending control information and a communication device. Background technique [0002] Long Term Evolution (LTE for short) is a long-term evolution of the Universal Mobile Telecommunications System (UMTS) technical standard formulated by The 3rd Generation Partnership Project (3GPP for short), which introduces Key technologies such as Orthogonal Frequency Division Multiplexing (OFDM) and Multi-Input&Multi-Output (MIMO) have significantly increased spectral efficiency and data transmission rate, and have been extensively developed in recent years. . A Long Term Evolution-Advanced (LTE-A for short) system is a further evolved and enhanced system of the 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 Aggre...
