Abstract
Disclosed are a method and a device for sending and receiving downlink control information. The method comprises: discrete user-specific search space is determined, control channel resources corresponding to the discrete user-specific search spaces being distributed discretely; and the downlink control information on the discrete user-specific search space is sent. Through the disclosure, the diversity effect of sending physical downlink control information is improved.
Claims19
A method for sending downlink control information, which is applied to an eNodeB, comprising:
- determining discrete user-specific search space, wherein control channel resources corresponding to the discrete user-specific search space are distributed discretely;
- and
- sending the downlink control information on the discrete user-specific search space.
A method for receiving downlink control information, which is applied to an user equipment (UE), comprising:
- determining discrete user-specific search space, wherein control channel resources corresponding to the discrete user-specific search space are distributed discretely;
- and
- detecting the downlink control information on the discrete user-specific search space.
A device for sending downlink control information, which is applied to an eNodeB, wherein the device comprises:
- a first determination module configured to determine discrete user-specific search space, wherein control channel resources corresponding to the discrete user-specific search space are distributed discretely;
- and
- a first sending module configured to send the downlink control information on the discrete user-specific search space.
A device for receiving downlink control information, which is applied to user equipment (UE), comprising:
- a third determination module configured to determine discrete user-specific search space, wherein control channel resources corresponding to the discrete user-specific search space are distributed discretely;
- and
- a detection module configured to detect the downlink control information on the discrete user-specific search space.
