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.
Abstract translation: 本发明公开了一种在物理上行链路控制信道（PUCCH）上发送信息的方法和装置。 该方法包括以下步骤：用户设备（UE）从信道状态信息（CSI）中选择要发送的信息（S1）; 从CSI中选择的信息是通过混合自动重传送达确认信息和调度请求（S2）中的一个或两个在PUCCH上发送的，这使得基站能够不仅获得CSI中的信息，而且获得CSI中的一个或两个 混合自动重传确认信息和来自PUCCH的调度请求。 本发明避免了现有技术中由UE丢弃所有CSI引起的系统下行链路吞吐量恶化的问题，避免了由载波之间的ACK / NACK绑定引起的下行链路载波上的不必要的数据重传影响系统下行吞吐量的问题 。
