Abstract

The invention discloses a method and a device for transmitting a response message. The method comprises the steps of determining the carrier number configured by user equipment (UE); when the carrier number of the UE is larger than a preset threshold, configuring physical uplink control channel (PUCCH) resources which are used for transmitting the response message for the UE according to types of carriers and the accompanying information transmission state, wherein the accompanying information transmission state is used for indicating whether a physical downlink control channel (PUCCH) of the main carrier is transmitted while accompanied by PUCCH information; and using configured PUCCH resources to transmit the response message. The method and the device solve the problems that the UE is required to feed back a large amount of acknowledgement / negative acknowledgement (ACK / NACK) information due to carrier aggregation in the prior art, at the same time when the ACK / NACK information is effectively transmitted and fed back, unnecessary downlink data retransmission can be effectively restrained, and the validity and the reliability of ACK / NACK information transmission are improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for transmitting response information. Background technique [0002] With the rapid development of the Long Term Evolution (abbreviated as LTE) system, the 3GPP has gradually carried out research work on technologies related to LTE-Advanced. Compared with the LTE system, the LTE-Advanced system has greatly improved in terms of key technologies, and successively introduced carrier aggregation technology (CA), relay (Relay) technology, Comp technology, enhanced multi-antenna technology and uplink multi-antenna technology and other technologies. [0003] However, the reason why the carrier aggregation technology is proposed is that in terms of system bandwidth, LTE-Advanced needs to support higher uplink and downlink transmission rates, and the downlink needs to support a data transmission rate of 1Gbps, so the bandwidth needs to reach 100MHz to meet the requi...
