UPLINK CONTROL INFORMATION TRANSMISSION ON BACKWARD COMPATIBLE PUCCH FORMATS WITH CARRIER AGGREGATION |
摘要 |
A method for reporting uplink control information (UCI) on a user equipment (UE) is described. A number of bits for a channel quality indicator and/or a precoding matrix index and/or a rank indication (CQI/PMI/RI) is obtained. A number of component carriers with hybrid automatic repeat request acknowledgement (HARQ-ACK) reporting is also obtained. A total number of HARQ-ACK bits is further obtained. A number of HARQ-ACK bits that can be carried on the physical uplink control channel (PUCCH) is determined. Bundling is performed on the total number of HARQ-ACK bits to be reported to fit the total number of HARQ-ACK bits to be reported into the number of HARQ-ACK bits that can be carried on the PUCH. A backward compatible PUCCH format is used to simultaneously carry the CQI/PMI/RI bits and the HARQ-ACK bits.
