METHOD AND SYSTEM FOR TRANSMITTING DOWNLINK CONTROL INFORMATION |
摘要 |
<p>The present invention discloses a method and a system for transmitting downlink control information, wherein when a base station is not configured with a carrier indicator field, the base station transmits a physical downlink control channel bearing the corresponding downlink control information on each downlink component carrier in a user equipment's physical downlink shared channel (PDSCH) carrier set, and the user equipment detects the corresponding downlink control information on each downlink component carrier in the configured PDSCH carrier set. When a base station is configured with a carrier indicator field, the base station transmits the physical downlink control channel bearing the corresponding downlink control information on each downlink component carrier in the configured physical downlink control channel (PDCCH) carrier set, and the user equipment detects the corresponding downlink control information on each downlink component carrier in the PDCCH carrier set. The PDSCH and the PDCCH carrier sets are configured by the base station. The present invention can avoid multiple times of blind detection and can implement the transmission and detection of multi-carrier downlink control information.</p> |
