Abstract
An uplink control information (UCI) transmitting method is provided. In this method, a user equipment (UE) receives a configuration signaling, determines a candidate physical uplink control channel (PUCCH) set corresponding to an acknowledgement (ACK)/negative acknowledgement (NACK) resource indication (ARI), receives a downlink grant signaling and downlink data corresponding to the downlink grant signaling, generates hybrid automatic repeat request ACK (HARQ-ACK) bits, performs processing for UCI bits including HARQ-ACK, determines the PUCCH used to transmit the UCI bits in the candidate PUCCH set according to an ARI in the downlink grant signaling, and transmits the UCI bits on the determined PUCCH. The present disclosure further provides an aperiodic channel state information (A-CSI) transmitting method. In this method, a UE receives an uplink grant signaling, determines whether an A-CSI report is triggered according to a CSI request field in the uplink grant signaling, determines a CSI process to be updated after determining that the A-CSI report is triggered, and transmits A-CSI on an uplink component carrier (CC) carrying the A-CSI report.
