摘要：
The embodiments herein relates to a method in a user equipment (305) for enabling a base station (301) to schedule the user equipment (305) in a wireless communication system (300). The wireless communication system (300) is in Multiple Input Multiple Output, MIMO, mode and comprises four transmit antennas. The user equipment (305) is connected to the base station (301) via a radio carrier (302). The user equipment (305) determines Channel State Information, CSI, based on information about a Common Pilot Indicator CHannel, CPICH, which CSI comprises Channel Quality Information, CQI, a Rank Indicator, RI, a Precoding Channel Indicator, PCI, and an Hybrid Automatic Repeat reQuest ACKnowledgement/Not ACKnowledgement, HARQ ACK/NACK. The user equipment (305) transmits the CSI to the base station (301) over a plurality of Transmission Time Intervals, TTIs, enabling the base station (301) to schedule the user equipment (305).
