METHOD FOR TRANSMITTING CHANNEL STATE INFORMATION AND USER EQUIPMENT

摘要

The invention provides a method for channel state information (CSI) transmission, wherein the method comprises: a user equipment (UE) sends, according to a transmission mode indication signaling, the cycle CSI of one or multiple downlink cells on a Physical Uplink Control Channel (PUCCH), wherein the transmission mode indication signaling indicates the information about the number of the downlink cells whose cycle CSI can be sent by the UE simultaneously. The invention also provides a UE. The invention effectively reduces the affection on the system due to the delay or discarding of the CSI report of the downlink cells, thus enhancing the performance of the system.
