METHOD AND BASE STATION FOR TRANSMITTING DOWNLINK CONTROL INFORMATION

摘要

Provided is a method for transmitting downlink control information, and said method includes: a base station sends the downlink control information (DCI), which is used for scheduling the physical uplink shared channel (PUSCH) and is carried in the DCI format, to the user equipment (UE); wherein said DCI format is used for scheduling the PUSCH transmitted in a single-antenna-port in a component carrier, and the payload of said DCI format used for scheduling the PUSCH transmitted in single-antenna-port in a component carrier is the same as that of the DCI format used for scheduling the PUSCH transmitted in multiple-antenna-port in a component carrier. The present invention also provides a method and base station for transmitting downlink control information. The present invention enables the single-antenna-port and/or multiple-antenna-port to transmit PUSCH during the scheduling of a component carrier of the long term evolution-advanced (LTE-A) system.
