METHOD AND A DEVICE FOR SENDING AND RECEIVING DOWNLINK CONTROL INFORMATION

摘要

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 present invention, the diversity effect of sending physical downlink control information is improved.
