Method for sending and detecting downlink control information
First Claim
1. A method for sending downlink control information comprising:
- a base station carrying the downlink control information in a physical downlink control channel, and sending said physical downlink control channel through downlink component carriers, wherein said downlink component carriers comprise an anchor component carrier and a prime component carrier, said anchor component carrier and prime component carrier are semi-statically configured by higher layer signaling, and said anchor component carrier and prime component carrier are UE-specific anchor component carrier and prime component carrier;
said base station bearing first type downlink control information on said anchor component carrier, and bearing third type downlink control information on said prime component carrier, whereinsaid first type downlink control information bears one or more types of uplink scheduling information, downlink scheduling information and uplink power control information of said anchor component carrier on which said first type downlink control information is borne, said third type downlink control information bears indication information of second type downlink control information, and said second type downlink control information bears the uplink scheduling information and/or the downlink scheduling information of one or more component carriers.

Abstract
A method for sending and detecting downlink control information is provided. A base station carries the downlink control information in a physical downlink control channel, and sends said physical downlink control channel through component carriers. Said base station bears first type downlink control information on an anchor component carrier, and bears third type downlink control information on a prime component carrier, wherein said first type downlink control information bears one or more types of uplink scheduling information, downlink scheduling information and uplink power control information of its component carrier, said third type downlink control information bears indication information of the second type downlink control information which bears the uplink scheduling information and/or the downlink scheduling information of one or more component carriers. A terminal detects the first type downlink control information on the anchor component carries and detects the third type downlink control information on the prime component carrier.

11. A terminal, comprising a detection module, wherein:
-
a base station carries downlink control information in a physical downlink control channel, and sends said physical downlink control channel through downlink component carriers, wherein said downlink component carriers comprise an anchor component carrier and a prime component carrier, said anchor component carrier and prime component carrier are semi-statically configured by higher layer signaling, and said anchor component carrier and prime component carrier are UE-specific anchor component carrier and prime component carrier; said detection module is configured to;
blindly detect first type downlink control information on said anchor component carrier, and blindly detect third type downlink control information on said prime component carrier;wherein said first type downlink control information bears one or more types of uplink scheduling information, downlink scheduling information and uplink power control information of said anchor component carrier on which said first type downlink control information is borne, said third type downlink control information bears indication information of second type downlink control information, and said second type downlink control information bears the uplink scheduling information and/or the downlink scheduling information of one or more component carriers.
