Problems solved by technology

[0007] In the study of the existing technology 2, it is found that under the carrier aggregation of the LTE-A system, there is a scenario where the channel correlation of the aggregated multiple downlink carriers is low, and the channel correlation of the two carriers is low when the two downlink carriers The correlation between right and wrong transmission of data transmitted on the Internet is low, so the probability of right data transmission on one carrier and

Embodiment Construction

[0087] An embodiment of the present invention provides a method for transmitting information on a physical uplink control channel, and an embodiment of the present invention also provides a corresponding device. Before describing the embodiment of the present invention, at first the nouns involved in this scheme are described as necessary, including as follows:

[0088]Channel State Information (CSI, Channel State Information) is used to support dynamic scheduling and MIMO technology. It is periodically fed back on PUCCH and can be divided into two types of feedback. The main feature of the first type of feedback is that only wideband channel state information is available. Feedback (the content reported in different reporting modes is different, for example, mode 1-0 only needs to report wideband CQI, mode 1-1 needs to report wideband CQI and PMI), usually called wideband CQI feedback (although it is referred to as wideband CQI feedback, but It corresponds to the feedback of ...

Abstract

The present invention discloses a method and a device for transmitting information on a physical uplink control channel (PUCCH). The method includes the following steps: a user equipment (UE) selects information from channel state information (CSI) to transmit (S1); the information selected from the CSI is transmitted on the PUCCH with one or both of hybrid automatic retransmission acknowledgment information and a scheduling request (S2), which enables a base station to obtain not only the information in the CSI but also one or both of the hybrid automatic retransmission acknowledgement information and the scheduling request from the PUCCH. The present invention avoids the problem of system downlink throughput degradation caused by dropping all CSI by the UE in the prior art, and avoids the problem that system downlink throughput is influenced by unnecessary data retransmission on a downlink carrier caused by ACK/NACK bundling among carriers.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for transmitting information on a Physical Uplink Control Channel (PUCCH, Physical Uplink Control Channel). Background technique [0002] Long Term Evolution-Advanced (LTE-A, Long Term Evolution-Advanced) is a further evolution and enhanced system of the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) LTE system. In the LTE-A system, a Carrier Aggregation (CA, Carrier Aggregation) technology is introduced to meet the peak data rate requirements of the International Telecommunication Union for the fourth-generation communication technology. In carrier aggregation, the spectrum of two or more component carriers (Component Carrier) is aggregated together to obtain a wider transmission bandwidth, where each component carrier can be configured to be compatible with the LTE system, and each component carrier Carriers have an indepe...
